Comp Cams recommendation evaluation

Nothing like a Comp Cams variable cam recommendation lol. Unfortunately lots of the big name cam grinders out there have crappy tech lines. Call Bullet Racing Cams, they are one of the best at speccing cams. http://www.bulletcams.com/
Don't get hung up on that 6500 RPM number. Your compression will likely be too low for a cam of that size (ie makes power at 6500) to run happily on the bottom, especially if your converter is or near stock.
The Rhoads lifters might be the ticket here, but they carry a $275 price tag.
