I need a goal for my next engine and so far Ive already planned on a roller cam and AFR 195 heads, BUT what I cant decied on is if I want to go a 383 sb with 6 inch rods or a 391 ( 3.835 stroke ) with 5.7 rods. the 6 inch rods wont fit on the 391 otherwise Id do that. I figure the 391 will give me more grunt but the 6 inch rods will feel smoother ( more like a new truck/ Ls1 ) or am I just being retarted. what do you guys think. P.S, a big block is kinda out of the question cause its way exspensive and not really legal in CA in a halfton.
