I don't think anyone has really conclusively showed that a short stroke LS-based engine is worth doing over say a 3.622 stroke based engine. Is your main reason to do this because of a weight break for the smaller cubes or something else? I have zero experience trying to build an LS-based combo for a class, but I 'hear' about folks running 9.5:1 - 10:1 for classes, though I have also heard of NMRA SSO guys running up to 11:1 for that class.

Tim meagher tried the 310cu with junk parts and went faster that had ever gone but the motor only lasted 6 runs used stock bottom end to see if would make more power
I am willing to try it
I think that i will put the 6.0L together because I have everything to do so
then I think I will try stock 4.8 short block to see if it could be fast
then if it is I will put together forged 4.8 short block
I am just trying to see what other think about the small cu because of limited turbo size
thanks to everyone that posted reply
