Camshafts and Compression

As to your Rhodes lifters. IIRC you can tune them with oil viscosity and/or oil-pump pressure/volume.
IMHO, I think if a guy worked with them, they could make an excellent street-strip combination; like a poor-man's VVT.
I shouldda tried them on my 292 cam but I wasn't smart enough back then. (1999)
Yeah, I was thinking along those lines at the time - like a simpler VVT.

Possibly with a lower compression street engine (maybe 9.5:1 or so?) they would be more suitable.

I probably should have put a solid cam in this engine.
