thanks for the feedback so far.
walt... i was looking at the hei and the headers at stovebolt. the offy intake was another one i was thinking of. now it looks like the offy wins.
orange...thanks for the info on the cfm. the tbi holley 670 is rated for up to 275 hp. that is why i thought that would work. i like your choice of cam. i have seen people talk about "sm465", what is it? trans i guess, but what kind? also what kind of gas mileage do you get?
