Yes. Try a custom cam from Ed Curtis. what Intake will you be running and what injectors?

where can i find out more about this guy ed curtis. i might just port out my cobra manifold as for injectors i have 24lb stock do you think i should move up to 30lb

I will see where i can find that info for you. I think you should get 30's. Once you get that cutome cam and heads get it Dyno tuned and that car should haul ass. [Wink] [burnout] [burnout]

I forgot to mention that the heads wont work with the stock 302 unles you notch the pistons.

yeah, about notching the piston im going to school (wyotech) and am taking high performence engines class next semester so i will be doing it all there about how much power do you think ill be getting. id be glad if you could get me more info on the cam

Unless you plan on stroking the motor, a lot of guys don't reccommend the 185's for a stock block, even Ed Curtis said so himself. There is a guy on WCF with the 165's, a cobra intake and a cam that dynoed at 265 I think. Why not go all Trick Flow? The best intake for the AFR 165's are the Edelbrocks right now, and for the 185;s the Holley Sytemax.

Go giants

AFR 185's on a 'race' 302 shortblock = perfect.
for the street, 165's make more sense (smaller cam, lower rpms, etc.)

How high do you want to Rev the motor? Ed has some stout performers out there. I can rattle off several of them in detail. I've talked to him about them and some of the ingredients. If you plan to stay under 6200 the 165's will be fine. Definitely use an Edelbrock intake. They work extremely well with these heads. Tell me the basic goals of your setup and weight and I can give you more specific info and examples to compare to. Is smog a concern? If it is then you can kiss big power goodbye NA.

Glenn, I dont think that stanger 91 has AFR 165's. Last time I heard, he had Edelbrock 6037's. You're right about him having a cam, but i'm pretty sure he still has the stock cam. So basically, crappy heads and crappy cam = weak numbers
 
Posted by AaronC (Member # 86) on :
 
I had 165's with 2.02 valves but still had a 165 port. Cam specs were 224/218 .555/.528, 111 LSA, with 10:1 compression. Standard performer intake. Car drove just a tad above stock, I loved it. Stepping up the cam, porting the heads, and lower intake to match. Also the RPM upper is going on with 10.5 compression this time

Iwas talking about stanger having the 165's I threw him in there just to show his numbers as well. I was talking about whiteGt's combo.

265 rwhp out of an AOD (if I think I know the car you're talking about) is pretty good.
Account for the AOD drivetrain losses, and that's probably 285+ rwhp in a T5 car.
 
Posted by MustangSS (Member # 1689) on :
 
I think those are great choices but why not go the whole 9 yards and get a new intake. The Trick Flow track heat is a great one. those are definately good choices though. [patriot]
 
Posted by venomous93 (Member # 1992) on :
 
i have thought about it and im just going to leave my cobra motor stock and i going to save up some more cash so i can buy a built motor any companies you guys recomend
 
Posted by 93PONY (Member # 60) on :
 
Unless there's something wrong with the stock shortblock, there's really no reason to buy a built one.
 
Posted by HungryHippo (Member # 537) on :
 
might i suggest a crane 2031 cam for a stock 302 cobra [Smile]
 
Posted by venomous93 (Member # 1992) on :
 
hey 93 pony what heads do you suggust i put on the stock short block
 
Posted by venomous93 (Member # 1992) on :
 
one more thing to say giants kick ass
 
Posted by 93PONY (Member # 60) on :
 
AFR165's, custom 'Ed' cam, & either a ported Cobra intake, or ported E-bock. Probably stick with the Cobra since it goes with the car.
That's what I'd do if I wanted to run 114+ in a full weight cobra....& pass smog.
 
Posted by jmcclesk (Member # 1355) on :
 
TEA- trick flow heads, track heat intake, trick flow stage cam 335hp to the rear wheels 12.04@113.4
 
Posted by 93PONY (Member # 60) on :
 
If you're going to buy high $$$ heads, might as well buy a cam to match.
Big heads + small cam does work for upper rpm HP, but a nicer cam would give more low end TQ for a street car. Not to mention more average power under the curve.

Ed also sells PS (pure street) heads that are comparable in price to TEA, yet flow significantly better.

I don't think you need to spend that kind of $$$ though.
 
Posted by venomous93 (Member # 1992) on :
 
everybody keeps telling me about the ed curtis cam and stuff but knowbody can give me any info on him or where i can get a cam by him can you 93pony.

send him an e-mail. if you're really interesed in getting the parts, try and call. he can be hard to get a hold of sometimes but is well worth it.

Posted by venomous93 (Member # 1992) on :
 
thanks alot ray ill look in to it
 
Posted by ray95 (Member # 752) on :
 
No problem....anytime. Good luck with everything.
 
Posted by 93PONY (Member # 60) on :
 
He's a LOT easier to get a hold of now.
He quit his job to work full-time in the shop.

Grab a pad of paper & a pen when you talk to him.....he'll be spouting off info so fast you'll forget most of it unless you write it down!

BTW, one of his customers has a 93Cobra, w/stock shortblock it's gone 120mph in the 1/4 I believe. Of course it's not a smog legal setup, but it does make excellent power!
 
Posted by shade-tree (Member # 298) on :
 
pure street racers (heads, cam , intake) are in the 130 mph range, just adding fuel to the fire.
plenty of racers out there designing cams.

hey 93pony one more thing i wanted to ask is, is he expensive and how much money should i be expecting to spend on the heads and cam
 
Posted by cobraman1994 (Member # 467) on :
 
the cams are 350 i belive. not sure on the heads.
and when i have the money, ill be going through him for my heads cam intake combo also [Big Grin]

SO THE CAM IS 350 DOES IT COME WITH LIFTERS AND ALL THE THE ACCECORIES

Ed's cams are $325 to your door....& WORTH THEIR WEIGHT IN GOLD!
Comp, Crane, Isky, AFM, etc are all 4-5 years behind Ed!
You can get box-stock AFR's anywere. I think most places sell them for ~$1300. Figure another $150 for a ported lower if you stick w/the Cobra. You'll be able to get by w/the 24's if you up the pressure, but 30's should be on the list....along w/a calibrated mass-air & idealy an A9L to replace the crappy Cobra computer. Probably need a 9-position timing chain...Ed sells them for $90. Misc. gaskets & stuff will also be needed.

You can use your stock lifters as long as they're in good shape. You could also use your stock 1.7 roller rockers & have Ed grind the cam for them.

I spent NO where close to what TEA charges retail. [Eek!] I bet what i spent on the heads is closer to the cost of a set of afr 185's

Right on! [patriot]
Dealers licence?
They're very nice heads, just too much for the average street car....with a price to match.
 
Posted by season'd 88 (Member # 169) on :
 
considering the mods listed in your sig, i would personally choose the edelbrock performers, the crane 2031 cam, and port the factory cobra lower myself. why not wait untill your motor wears out, then go with the wizz bang stuff on top of a healthy strocker. just an idea. btw, that 2031 cam was specifically designed as a performance replacment cam for the 93 cobra, using your factory 1:7 rockers. good luck either way.

Yeah, I'd say that's overly optimistic. Of course, every flowbench will be different.

Since the heads are coming off, you're going to notch those pistons (can't remember if you did that already... )& slap a nicer cam in there right???
I can recomend some healthy Comp cam lobes. [Big Grin]

Make sure you post dyno numbers and timeslips. After reading years and years worth of infomericals about these cams on corral.net, some of us are curious [burnout]

  • No one locally runs an "ed cam"
  • www.corral.net/forums is as cliquey as 7th grade.
  • For the past year, consistantly the fastest/faster stock bottem end all motor local 5.O's have run an off the shelf cam with "good" flowing heads. Jon, Scott, Drew, Jim, ect [Wink]
  • Only cool local 5.O owners run a 3 inch crank pulley, sorry I didn't make this fact up [dance] [Wink]
  • There are many other factors than the heads and cam you run to determine your ET. Look at shade-tree's stock bottem end/heads/cam 12 second combo.

What cracks me up is people doubting what these guys run on the corral for the pieces they have. Look at what Shadetree ran with the stock motor. 12.9's right? Now what if he had a motor that cranked out 320-355 RWHP and had a longer AVG power band to 6200-6500, now what would he run? All of a sudden those mid 11 cars at 118 don't sound so unrealistic now. Camara90's car is a perfect example of a street 347 at 3400 lbs. Now what would Shadetree run with that motor? 10's? Has a shot, I'd say. Wait till Nate's car hits the track with a tad more power and 200-300 lbs less weight than Mike. Lots of Ed's customers have run FMS cams/Edelbrock headed combo's before making the switch. What I find funny is you can call Comp Cams themselves and ask them what they'd recommend (custom wise) and have it not be far from their catalogue stuff. Then you call Buddy, Brian, Ed and they take Comp Cams lobes and make more power using Comps own stuff! I know of several grinds (from master lobe list) which lobes were used in these setups. After looking at the lobe profiles you can see what works with these setups.

I'm wondering what Dan's old '79 is going to run. The new owner picked up the car and his 13:1 331.

9's on motor? Thing only weighs ~2600 lbs. raceweight. I'd be surprised at anything under 400rwhp.
 
Posted by cobraman1994 (Member # 467) on :
 
2600 lbs????????????????????????????????? [Eek!]
that motor is designed for nitrous right, or was that another one he had for sale? oh boy [Eek!] [worship] [burnout]

Posted by shade-tree (Member # 298) on :
 
I don't know, you'd have to ask Dan or the new owner. Stock block, so I imagine 9's is the upper limit no matter how much N20 the rotating assembly can handle.
 
Posted by cobraman1994 (Member # 467) on :
 
i could deal with 9's NA. LMFAO
 
Posted by st5150 (Member # 51) on :
 
Aaron- I agree with what you're saying, but until I see it run down Sac raceway, it won't make it on my "fact list".
I think everyone here agrees "what-if" timeslip math, combo math, dyno math, ect is all kind of shady at best. In the mean time, I'm going to sit back and wait for the historical trend to change [burnout]
 
Posted by AaronC (Member # 86) on :
 
Sawson- My point is that it IS happening. Just hasn't happened in Sac yet. So these cars do exist, and aren't just internet myths. Just cause I haven't seen a pure street car run in person doesn't mean they don't run the #'s. Give it time and these cars will be popping up locally. That's all I'm trying to point out.
 
Posted by shade-tree (Member # 298) on :
 
hey according to my spectacular calculator (?)
340 rwhp in a 3600 raceweight car will go 12.2 @ around 111/112
not bad at all [worship]
 
Posted by st5150 (Member # 51) on :
 
Aaron- I don't doubt those guys run those times... heck, Bob Cosby use to run 12.5@108 mph with his stock motored 5.O LX, but lets face it, his stock motored 5.O with 4.30's, 28inch slicks and skinnies, ect was nothing like what our true-daily driver stocker 5.O's were. What I am saying is that many major and minor details are more than likely left out when talked about online [Smile] After 2-3 years of hearing about it, many of us can't wait to see an "ed cam" car run Texas type numbers here in Northern California [patriot]
 
Posted by AaronC (Member # 86) on :
 
I agree 100%. A perfect example of this but an LS1 analogy would be Raughammer from Houston Texas. Ran 10's with a stock bottom end LS1 with Heads, Cam, LS6 intake, Converter etc. People doubted it all over and then Mr. Jantzer popped up at Sac Raceway and lit off a 10.7 at 125. There it was a Raughammer Jr. at Sac Raceway, LOL. I agree there's several details that get left out and that's where you have to try to nit pick to find as many little things. As you do, I like to stick to facts as much as possible. I think Jon's and Shadetree's cars are both perfect candidates to lay some serious ET/MPH's down like these Ed cars do, and then some. I like racing but I picked the wrong car to go for optimum ET/MPH. I'll always need more Power to even contend with these guys. Maybe someday I'll pick up an LX and go all out.
 
Posted by Mr Paint Job (Member # 1708) on :
 
guess i'm not cool, i have a 7" crank pulley.

Shade-Tree, it was going to be a fast car but mike from ebr bought it so you can just forget about real hp. He plans on sticking a tfs stage III hydrolic roller in it with a two stage (100hp/100hp) nitrous kit on it. [Roll Eyes]

that's right, small hydrolic roller on a 13:1 motor.

it also has twisted wedge heads with a TEA 185 port job.

my guess, 550-600 rwhp on nitrous.
 
Posted by jmcclesk (Member # 1355) on :
 
TEA made a mistake on the heads. I had to make a .070 cut on the pistons (intake valve)to get everything to clear. I dont have enough clearance to do a larger cam. .080 exuast side and .080 on the intake side. All i need is one good 60'foot and i WILL get that 11 second pass. [burnout] [burnout]

Posted by jmcclesk (Member # 1355) on :

Hey Jon, what cam are you going with?
 
Posted by jmcclesk (Member # 1355) on :
 
I am not sure. AFM stuff looks good. The problem is P-to-V clearance. like i said, with the trick flow cam .080 clearance on the intake and exuast that is not a lot to work with. One part of me wants to call AFM and ask rick for his pick, then call ed and get one from him and then do a three way comparsion to put this debate to rest [Eek!] [Confused] my guess is that there would no more than a 15-20hp gain from the trick flow stage one. thats just i think i could be wrong [burnout] [burnout]
