Solid flat tappet cam

The solid lobe ramps are able to be a bit more agressive. They not only RPM higher but quicker in most cases. RUmblefish nailed it about the adjustability. As long as you get a good high quality rocker arm, adjustment will be something that is seldom done. It's probably hoestly now become a toss up in the flat tappet department. Because technology has allowed hydraulic flat tappets to almost catch solids in power. It really becomes more of a personal preference I guess. "I" would think a solid camshaft would be more of a match woth what you are building. Old school tunnel ram through the hood kinda thing......I don't know if that's how you're thinkin or not.
