Ok, it's like this...
I don't want to keep the original engine in my 93. Simple as that. I know I'm on borrowed time as it is, pushing the amount of boost, coupled with the junk 93 Pistons...so it's like this...
If you had "X" amount (less than $2k) what shortblock would you build? Keep in mind it must be 302-based (I wanna use the same distributor, headers, etc) but I'd be getting a new balancer and flywheel...so strokers are in. I am SOOO on the idea of a 347, but a simple 306 sounds good too. I've got Heavily-ported RPM heads (2.02) and the cam will be the Stage 1 Trickflow (possibly different if the combo would warrant the change). The Blower stays. ![[Wink]](wink.gif)
What's your opinion?

Go to your local junkyard and pickup a nice $100 302 shortblock. You can make just as much power with it as any other stock block based 306/stroker and it's much more economical. Then you can take that $2000 and put it towards a REAL shortblock down the road.

You have a powerdyne blower right? I'd keep the 302 and use that $2K towards a S trim once the powerdyne blows up.

the 331 and 347 posts here are cracking me up. If his car was n/a id say go for it but since he is a poweradder car it dosent matter if he has a 331 or a 347 or a stock 302 the block will split at 550hp so lose 100 bucks when this happens or 2500 bucks its your call. So save the money for a r302 and run the hyperutectic cobra shortblock i have seen well tuned hyperutectic shortblocks take 500 boosted hp easy as long as there is no detonation.
with the heads he has a good cam and 10-12lbs of boost 500 rwhp easy.

Call me crazy here, but I don't see any combo listed here that will even come CLOSE to 550 rwhp. With those heads and cam, and for damn sure that stock cobra manifold if that what he's planning on going with, he wont make block breaking power.
From what I've seen, he is going to need the extra cubes just to make the thing run half way strong. JMO

I wasn't aware he had a Powerdyne but ported Edelbrock heads a TFS stage 1 cam and a Cobra intake will make 500rwhp eaily with boost.

As it sits, it was a solid low 12 sec car. I'd just slap the cam and heads on, but from what I've found, the 2.02's won't clear on the stock pistons. (note: I have not physically checked) If anyone has run this setup, and didn't have clearance problems, lemme know. As of now, I'm favoring a .030 302, Probe pistons with a 9-9.5 to 1 CR and a good set of rods. Basic rebuild throughout, with quality hardware. As for bustin' the block, I don't think I'm quite there yet.. ![[burnout]](graemlins/burnout.gif)
Edit: it's a Paxton SN-93. Pushes 10-11 lbs of boost.

imo maybe you should go for a sportsman block, if you can swing the extra cash, just so the thought of splitting the block isn't in the back of your head. But if not, GOOD LUCK. BTW, how much rwhp do you think your combo is going to make?

oh and were you saying that you were going to slap your heavily ported rpm heads on and stage 1 cam in? with 10lbs of boost on a completely stock bottom end?

Yes, I've been running 10+ lbs for about a year now on a completely stock 302. Daily driver, over 7k miles.

I found keith craft set up that is the most comparable with my stroker short block, and am I supposed to be offended that they refer to it as the "econo-stroker"?

The SN-93 isn't known to be too reliable either.... I'd still save the money for something else down the line. As for "stage 2" ported performer heads, they probably flow what AFR165/Trick Flow Twisted Wedges flow box stock, so along with that cam and 10ish psi of boost, you're looking at ~450 rwhp. I'm all for the stock bottem end. Your '93-95 short blocks can take 425-450 rwhp with no problem. I think Corbramanphil on here has put 50K+ miles on his 420rwhp 10psi boosted '94 short block and its still going strong.
