I would think if running manifolds you'd want a split with a bias on exhaust duration. The brand isn't going to make a difference so much as the cam timing that you get.

Does a summit mopar grind give you a profile that works with the bigger mopar lifter? many don't, and you lose a bit.




what? the cam comes with lifters....
AND FWIW 3 friends have run the same cam w/ logs and had good results.




You can buy it without lifters, I bought 2 last month on sale 57 each.

I was going to run it with a 383 but decided it wasn't the best choice for this one.

To answer the other question , I doubt it was ground to take advantage of the mopar .904 lifter.


pretty sure its a crane profile, hp280/hp290. looking at trying to bleed a little cylinder pressure with the extra duration and wider LSA vs the mopar 272-.455.
