i have a bbk cold air intake, bbk shorty headers, bbk full exhaust... it is a 4.6 gt and i was wondering if it was worth keeping the 4.6 block and changing all the parts in the engine for racing, not for professional racing just a serious hobby... Or should i buy a bigger block and get all racing parts put the time and money to get the bigger block into the gt... ANY ADVICE IS WELCOMED... plus i plan on a supercharger

get an mmr block with a forged rotating assembly.

I have built my own motor for 1900 with labor. That includes WAP block,Forged Assembly and a good reputable machine shop labor. If you wana go serious you could go with the MMR blocks and their assemblies. Its a good company.

+1 for mmr, but sure is fun doing it yourself
