which cam?

[SRT_DSTRHOLC]

Im going to be running the magnum heads and i wanted to know what cam to run. Xe274 or the 268. On Camquest it showed that the 268 made more torque and at a lower rpm, while the 274 made about only 10 max more hp and the heads will be ported later so im wondeing what i should do becasue i saw that mancini racing does offer a magnum head spring that will handle .525 plus up to 600 so im not that worried about the springs jsut want the best cam. More torque or HP

OUCH! Huge lack of info here. Start by describing the car and it's intended purpose.
Where do you want to cruise at on the Hwy.?

Compression?

If you are worried about making the cam last, buy the recommended springs from the manufacturer.

I have this in my 340, with nearly identical specs and it makes awesome power.

But I can't guarantee it will clear the heads with that much lift.

That one might work a bit better with your gears and compression though. (I have 10 to 1 Compression)
