Need cam guru thoughts/advice

Hard to know how the two cams really compare, ramp speed wise, without more data.
By what is posted, it certainly seems like the Bullet has faster lobes.
That isn’t always what the engine wants, but the better the heads are, the more likely it is that the engine can use it.

I’d also be curious as to why the Bullet cam was installed 4* retarded.
And, 4* retarded from where? The lsa or the recommended c/l(which might have been 100)?
It’s always best to specify exactly where the cam is(102, 104, 108, etc) instead of saying it’s “advanced” or “retarded” from some unspecified point.

Ultimately though, the only real way to know how they compare in that particular engine/car combo is……… to try it.

If the OP has the info, I’d be interested in knowing what springs and pressures the heads are set up with.

Not that this is good or bad, but the specs for the Comp look like it’s a 20-717-9.
