I'm not a cam expert, i'm sure someone will chime in with a suggestion for a substitute though

I'm the farthest thing from a cam expert, but cylinder pressure was a concern when I built my engine because it replaced a 400 with 100-105 PSI. That thing would start and sounded good but was pitiful otherwise. It needed over 20* of timing to even start to act right.

I replaced that with a 360 +.030, speed pro pistons, e-heads, RPM air gap, Doug's headers. The car has a 4spd w/ 3.91s.

I used a Howard's 711451-08 with the intention to preserve cylinder pressure. Ordered from Jeg's, shipped direct from Howards, arrived sooner than predicted.

The fellow who recommended it ran my numbers through some software and convinced me the Whiplash is not going to help unless you just want the engine to sound good. He has a little bit of a hate-on for them (many do) but everything he explained made sense.

Alternatively, Howard's recommended this one
