hey guy's i am in a bind with what to do over chooseing the right rotateing assembly for a 383stroker? here in the cold to bone north part of canada i have one place i can order all the performace parts i need.....

here it goes what i have looked at so far for the bottom end (3.75") stroker kit with a rod length of (5.7 kb dish) piston 10.3:1 copressoin with a /58cchead i imageine that it with what i see in the catalogue.the ratios change dramaticlly with chamber sizes for sure wow....

#2 assembly choice is a 6.0 rod length with a (srp dish piston )compression with 58 cc is 11.4:1 my question is whats the big difference with the piston heads?

you see this is the first stroker i have ever thought about building i am starting with a 4 bolt main LT1 corvette engine for this project it is going into a 80 chev siverado stepside short box.. i have the basics for the bore job and the die grinding and the cost but as per the norm i dont want to mess this up the first time out right.. I can get just about everything the parts shop order's most everything from the USA so i figured thta someone knows more about strokers that i ever will so thanks in advance.
