I ran a 396/325 combo and will be running the same motor in my 65 Impala. I thought it ran pretty good pushing my 4100 lbs 68 Impala to 11.70's . Checking out the specs compared to the 402/315 they are pretty close except I run 290 heads which have a little more intake port volume. Cam intake lift same at .398 but more for 402 on exhaust at .430 Then I did notice the intake manifold for the 402 really a "low riser" compared to the 396/325 which is a more of a "high riser" design. Makes sense than that manifold is the problem. Just wanted to throw my thoughts in.
