You are right the old 30-30 cam makes a very poor bower cam.
Made that mistake once.
Many of the other GM SBC cams work very very well thou.

The GM 350-290 crate motor comes with a high perf cam in it.
222-222 .450-.460 114...
Works bet when you degree it and advance it some.


The 327-300hp is a different cam Its basicly a baseline low perf "stock cam"

195-202 .390-.410-112. It will tend to limit the performance and power of this motor, with a blower.

Clairify which cam you have.
For the purpose you re seeking here are few that do work vey well.

Summit cam 1105
Crane HMV278-2 113801
Comp CS 268AH14 11-404-4
Crane H 288-2 113821
Anything of a similar nature. Use one of these with a 750 and 6 to 7psi boost and give the stock crate motor heads a home port job and you will add well over 100hp to your 350 with a 144 blower.
I am being very conservative.
Adding a 144 blower is a great way to wake up this low compression crate motor.
