Highest lift cam on stock pistons

[Unit 5302]

What MAF are you going to run?

If you are SD, I don't think the car will run for crap with the X cam.

At .542/.542 lift 224*/224* the X-303 makes the F cam look puny.

It's way, way, too much cam for stock heads. The X cam is made for power up to 6500rpm, your intake isn't the best for it, and your heads won't come close. Even fully worked stockers won't make more than about 220cfm intake. That's with bigger valves and everything you can do to them. A decent port job with stock valves will probably put you into the 170cfm range.

Not to be the voice of dissent here, but even an F cam is overkill on stockers.

If you want the X cam, throw a set of serious heads on it. Or N20, since from what I've seen posted, it's a good nitrous cam.
