do you guys think a holley 465 would be enough for my engine. i plan on doing a big street port with other small mods like removing the rats nest, exhaust, ect... should i get the 465 or go for the 600 cfm?

take it from some one who has been there. don't use the 465 if u do it will not make power in the top end. it will fall on its face and sputter at like 5000-6000 rpm's go with the 600. Switch to larger fuel lines like 3/8 or some thing and ur gonna need to run a fuel pump with at least more than 7 psi
