I run the voodoo 60303 and it's very tame/driveable in my 8:1 compression smogger 440 wiht 3.55 gears. Really, the MP .528 solid cam has proven to be the best all around street/strip cam for a mild 440 like yours with hp manifolds. But if you want to stay hydraulic you should look at the comp xe275hl or the lunati voodoo 60303. The 303 is a hair milder than the comp grind, by about 4* @050. The 268 will be too mild for you, especially with the 4-gear. For the intake, you should consider stepping up to a used edelbrock ch4b. Grind off the edelbrock letters and it looks like a stock intake but flows a bit better. Even the CH4B will be holding you back with those aftermarket heads though.
