A low deck 350 wont take a 4 inch crank(that I am aware of) The 3.875 crank just barely fits(unless there is a new crank Im not aware of.So,401 from some GM 350 blocks is the max. The 4 inch crank goes into a 400 block to make a 434(thats what I have)
Ive been trying to price out a boosted engine myself. So far I dont see building an LS 5.3(cheapest core) that makes decent power for less than 12k
some members here can piece meal used turbos for a lot less.I dont see how
hope someone will step up with a full parts list???
