I SAY 370 ON A DYNOJET.
THAT CAM SEEMS LIKE IT WILL KILL THAT MOTOR.
My wife's 442RWHP 347 has a cam that measures 248/245 on a 110LSA....& it's small compared to Yellow94GT's. ![[Smile]](smile.gif)
& yes, it does kill power down low. She only made 395RWTQ...but you don't even notice it with 4.30's. ![[Big Grin]](biggrin.gif)
yea but you guys run ported victor stuff. not 185's and rpm 2's.

Well I took my car to Force Fed today and was able to put down 370rwhp and I believe 388TQ I might have some possible valve float issues and my Rockers may need to be adjusted because it looks like they are hitting the valve covers or are possibly not adjusted properly. peak power is at 5800rpm for some reason ![[Confused]](confused.gif) The car does feel pretty fun drive and it definately moves out! All in all not that bad for a fully loaded GT with A/C and all the other accesories. hell I don't even have an electric fan LOL! maybe when I take care of those issues power will increase a little. So it looks like I owe VPRKLR some nachos ![[patriot]](graemlins/patriot.gif)

nice #'s! if ur runnin the 185's out tha box, then for surely, u will experience valve float. upgrade them springs. that cam is too big for them. i think those springs are only good till .550 lift... also i'd run 1 3/4" long tubes & 3" exhaust
few q's for ya:
what compression is ur motor?
58cc heads?
stock computer or tuned?

They are upgraded valvle springs ( I have to ask what kind) I think their 917-918'2 not sure. Compression is 10-1 and it is tuned. My friend already mentioned I might need some 1 3/4 longtubes and 3 inch exhaust LOL! I guess I will just take care of those issues after tax time. Hopefully I can take it to the track and get an 11 sec time slip.

Port the heads, intake and run larger headers(1 3/4" shorties with 2 1/2" exhaust). Upgrade the valve springs and check for optimal pushrod/rocker geometry. Spin that sucker to 6700 rpm's! You need all the breathing capabilities you can get with an N/A motor.
Then we're talking like 418-425 RWHP!
If not worried about smog, AFR 205's with the Nitrous exhaust port and edelbrock victor 5.0 intake. We run those heads on 500 horse 302's built for circle track!
you buy the nacho's i'll bring some beer!

Thats not all that bad. I made 360hp 370TQ with my 331 we thinnk it is 10:1, XE 274 cam, Untouched box stock victor intake and Victors jr's. 1 3/4 headers and 3" exhuast, and I ran it through a 3550. Had valve float too. I will get it back together one day. Bigger cam, better springs, port matching, and maybe more comp.

Yeah, I know I can get more power out of it if i change out my 1 5/8 longtubes and go with a 3 inch exhaust. I do plan on checking my pushrods and rockers though. I will focus on all that stuff in a couple of months. i remember seeing your car at the track, It was a nice setup you had

We've seen 410/410 with un-ported AFR185's, a custom camshaft (reverse-split), & RPM2 intake.
You do need to think about an electric fan.
917 valvesprings are what we use on Yellow94GT's 347 & my wife's 347 & have no issues till MUCH higher than what you're seeing. AFR's 'upgraded' valvespring kit sucks ass...if that's what you have. & If you're using 917's you would have had to have the valve pocket the AFR's enlarged since they are setup for a 1.46" OD valvespring & 917's are 1.55" OD. 917's also have enough open pressure when setup at 1.900" installed height to collapse a stock lifter. 917's are for mild solid-roller camshafts.
If you have 3/8th rocker studs that will be another cause for concern. As are aluminum rockers unless they are large-body rockers (like scorpians), but nothing is better than a steel rocker arm like Comps Hitech & Pro-Magnums.
Valvefloat will kill motors FAST if you have tight Piston to Valve clearance. Seen it too many times. I'd highly recomend taking care of the issue before racing this car. According to Tony McCurty at Comp (really knows his valvetrains), if you've floated the valves more than 1 or 2 times, the heads should have a valvejob & you should replace the valvelocks. They get beat up FAST.
I'm actually in the process of upgrading the wife's valvesprings again. The 917's have seen better days & she needs a little more pressure (in the right area) with her new 4130 Chromoly .120" wall pushrods. (heavy)
BTW, Yellow94GT's cam card states 248/248 108LSA....but that is NOT what it degreed in at. ![[Wink]](wink.gif) LOL

1 & 5/8th primaries can not 'swallow' the width of an AFR exhaust port.....165 or 185.
Even when you port the crap out of the primary....just too damn wide.
Even most 1 &3/4 longtubes need porting to swallow the AFR exhaust port.

Yeah, I will call to find out what kind of valvsprings were put on the car. I know they are not the AFR upgraded valvesprings. The Rockers I have are the Ford racing 1.6 rockers. maybe I should change those too LOL. I was told electric fans are not very ideal for a street car and alot of cars can overheat with them. That is the only reason I did not install one. I am not running stock pushrods or lifters either. I am pretty sure I have some comp cams stuff. I was their when they ordered it.

The only time I've had an electric fan equiped 5.0 overheat is when the fan did not come on. (faulty relay)
I would highly recomend an electric fan. I'm even thinking about an electric water pump for the wife's GT which is worth another 10+hp....but at a cost of over $500 for the one that works with the heater core....but we're already stressing the stock block....the car doesn't really need more power. LOL
Definately upgrade to 7/16th rockers/studs. I'd recomend Comp ProMagnums or HiTech(expensive). Aftermarket lifters are no better than stock unless they've been modified. Some Comp lifters come modified correctly (like what we run in my wife's & Yellow94GT's 347's). If you have modified lifters, you can run VERY stiff valvesprings provided you do not go overboard on open pressure (the camshaft can only take so much pressure).
The first time my wife's 347 was strapped down to FFP's dyno it put out 422RWHP & 388RWTQ. We found another 20hp from maximizing the combination. (valvetrain & cam swap). You can pop up over 400RWHP from changing a few parts.....& still keep that killer 388RWTQ.

Thats some good advice. I just found out that I have Pro magnum pushrods and Comp cams lifters. I will find out the exact type next week along with info on my valvesprings. I will definately get the vavletrain checked before I take it to the track and upgrade the rockers since my ford motorsport ones might not be cuttin it LOL!
