"...im seriously considering getting comp to grind me a 305 magnum on 114, then putting rhoades on it..."
Back in the late '80's, Comp made a cam with the 292H Magnum lobe on the intake, and the 305H Magnum on the exhaust. I put one of these in our 2nd gen 455 bracket engine. With Rhoads lifters, it would still idle good enuff and make enuff low end power to leave from an idle, with a stock converter. But, the engine had 72cc iron heads on it. So, I don't know how that cam would have done with less than 10:1 CR.
Anyhow, if your gonna buy a custom cam anyhow, you may wanna get 'em to make it a dual pattern.
