Buick 400/430/455 Street Cam Selection Guide

These are a set of good performance cams for Buick big block engines. I am choosing one for my '67 GS400 which is about to receive a 455. The car is equiped with a M21 4 speed transmission coupled to a BOP 10 bolt with 3.36 gears. It also has A/C, and when I stop at a light and the A/C cuts in, I don't want it to stall!

I am not concerned about getting a lumpy sounding car, which seems the first concern of many camming up their motors. I want a car that runs nice with whatever top end I can get. I definitely don't even want to go over about 5500. I have had pretty good luck sticking a set of Rhoads lifters on relatively mild street cams and will almost certainly do it this time. I suspect that the Rhoads would like a cam ground on a tighter rather than wider lobe seperation.

The 455 is a very popular performance build, so I thought there might be some interest in the information by those builders.
