You could subtract 20 degrees of overlap Int & Exh and it would be a much better street cam. Especially with low CR.
Ran an Engle in a 406" SB street motor - 214/224 @.050, .470/.504, 110 CL - and it ran great: perfect throttle response even with stock converter, 3.23 gear, 28" tire, handled AC, pulled 17 MPG, but still sounded pretty rumpity.
Rarely have I seen a street car where the rumpity idle was the main build consideration actually run well @ lower RPMs.
I scaled that SB Engle up 1 lobe spec Int/Exh for a 446" RB street build, and got the same results in a 4-speed early-B wagon.
