Im about to swap a B body LT1 in my 92 Z28 while the engine is out I want to put some parts like .030 pistons,cam shaft and aluminum heads about the pistons I cant find LT1/LT4 pistons but I was told in Thirdgen.org that the old chevy pistons will fit but they are heavyer and I found Speed pro pistons they got alot of pistons but I want to raise the CR the stock CR is 10.5:1 is that right? If I want to raise the CR do I need to use dome pistons? are these gonna work (http://store.summitracing.com/partde...0&autoview=sku or http://store.summitracing.com/partde...0&autoview=sku ) I got no experience about pistons so I need help with this and about the cam shaft I will go with CC306 and dual springs,about the heads I will port them and it will be a carburetor engine not FI I guess 650cfm is enough I will finish the set up with LTs,3.73,3000 stall(or suggest the best stall) I got another question is the 700R4 will fit direct to the LT1 or not?if not what do I need to do to make it fit?

The 700r4 will bolt up perfectly. I have a question though, why go carb? If your car is a 92 it's already injected, It would be cheaper to keep it injected rather then buying a new intake, carb, distributor, fuel system, etc. Just my 2 cents.

l2256-f piston is what i a running in my lt4.. and if you use the gm impala head gasket with the stock fbody aluminum lt1 heads and you will raise the compression.

The LT1 is already carburetor all I need is a 650cfm carb and fuel pressure regulator and Im done with it if I want to run it stock but I was thinking of something no one did it before a TPI on LT1 hows that sound? I guess impossible loool

joshh123 the pistons you are using got low compression ! I want to raise it not lower it I will go with .030 over and flat top
