cam i use in many builds is erson cams 620/620@050 236/242 on 112 have one with a 4/7 swap if your look for a cam . they sound good and seam to work good for street strip use .the rolling thunder edelbrock cam looks good to. very close to the ersons grind .i have used all of howards hyd rollers and alot of there solids rollers. there is 3 grinds that i use in ersons for most of my BBC builds . if you have a mark 6 block you have to watch the lift of the cam hi lift cams push up the lifter s up to hi and bleed off the lifter at full lift
