What kind of horsepower and 1/4 mile times could I expect from these things assuming all else was stock? What else would you change out for most power?

Heck better yet - what happens if I just drop in some forged low compression pistsons ? what kind of powere can i get?

 

Why would you want to run low compression pistons???

Anyway, the car will probably run somewhere in the 13's assuming everything else is stock. I have a stock 91 engine in my 86, it has SLP 1 5/8" headers and a shift kit (as if that makes any difference) and I ran a 13.8@104 first time out on a 2.2 60' time with 7psi. I've since tuned it and adjusted the blowoff valve so its running around 16psi today and its... fast. Without a blowoff, which is how the kit comes, its going to run probably 12-14psi so just make sure the tune is good and it'll return you with some good ET's. A good 60' and proper tune should send one into the 12's.
