Thanks Randy & I was thinking of switching, but Summit's cam is only $54 & that's hard to beat & made by Crane, too. But if I ever decide to swap the 383 for my 451, maybe a 3 bolt setup would be a better selling factor if I decide to turn it loose. But being in a truck, I think the one bolt would be fine.
Hope you've been able to enjoy some top down crusin w/ the Chally.



The number of bolts in the cam has to do with the valve action of the cam.

I really don't think a 1 bolt vs a 3 bolt would be a deal breaker in selling an engine .


Thanks John. Summit's 6400 cam has a power band of 1500 - 5K, lift @ .050 is 214 int/224 ex & advertised duration of 272/282. Lift is 442/465 & has a 112 centerline. Do you think this would be a good
cam for the truck? (3.55's w/ 35" tires.)
