i know bigger is usually better, and ive had good luck with my old 306 in the last car i built..now eleanor is facing another decision... i like the 331's, but the stroked smally to a 427 interests me, either one is definately getting a blower, also not sure if i want a kenne bell, or whipple up on top,, i would love to hear some input on combo setups that have worked for you guys, plus and pros or cons about either idea....thanks...cant wait till this part gets going....
