Aight, well its come the time for me to go ahead and get another engine built..so i came here since the advice thus far has been helpful.. i want to know which engine is quicker stock...and i want to know which one is a better motor to build on... the only motors that ive been familar with so far are 355,and a 400... so when i heard about a 327 block i was just wondering what exactly i was getting myself into.. thanks in advance for the responses...
