Suggestions and experience on engine combos

Hi everyone,

I've got a 1994 GT that I picked up a few months ago with 46K on it and without any mods (which I consider a find because I'm anal about good work and I'd rather have a car w/ no mods that w/ ones done poorly). Anyway, like most of you guys, I want more than what detroit gave me I already have plans on a Griggs setup for the suspension, 3.55 rear, and a T-56 to replace my T-5. My question is for suggestions on what block to run in front of all of this. Keeping in mind that this car is primarily a driver that I want to get healthy times at the track (and meet MA strict emissions )

Run a serious 302? 347? 351W? 393W or 408W? any problems w/ certain combos? Please be as detailed and techincal as possible.

Oh yeah, last and pretty important. No turbo, supercharger, or NOS suggestions. I prefer to be old school and naturally aspirated "All throttle, no bottle!"

Anyone? Anyone? (Bueller? Bueller?)

Ok, if I simplify my question (and yes I had checked other posts 89Sleeper, but none of them told me much because no one seemed to have a stroker w/ any miles on it in the 50K+ range) maybe I'll get a better answer. How much HP or torque is required to get into the 12's in the 1/4 (and am I dreaming to do this and keep the car a daily driver)? Can I do it with a 302 w/ a built up bottom end, 10:1 comp, Twisted Wedge heads and intake?

My main concern is that I had heard rumors about 302's getting alot of cylinder wear due to their relatively short skirt on the pistons, therefore, I was a bit hesitant to build up one. Is this just car show B.S.?
