your best bet is to ask Brian about the cam, but i would go solid, i have the same rockers with a mild solid comp cam 244/252 @.050 520/540 lift in a 3400 lbs demon, stock stroke 360 running low 12's, i would guess with the heads, the "small" 390", and the lowish 10.2cr, maybe something in the 248 to 252 @.050 range. Also as stated above sell the 650 and go to the Holley 950 HP.
