My old pump gas 511 C.I. pump gas 400 stroker motor had a Comp Cams solid roller cam in it that had 260 degrees at .050 on the intake with .420 lobe lift and 266 degrees at .050 on the exhaust with .409 lobe lift ground on a 108 LSA angle installed at 106 to 107 on the intake lobe. I used a set of Harland Sharp 1.65 ratio rockers on it also
That cam was very noisy and rumpity out the exhaust at 1400 to 1800 RPM, so much so that I had some young hot rodders lean out there window going down the road at 30 MPH in town one afternoon and ask me how much it cost to get my cars exhaust to sound that mean
I built that car and motor for street racing, not cruising in 2nd gear at light part throttle cruise that slow
Be careful on the cam duration at .050 and the lobe separation angle if you want it to idle nice and not be running in the rumpity and loping a lot RPM range at lower cruising speeds
