Default Crane Hydraulic Roller #169651

Refreshing from mechanical solid to hydraulic roller.
Combination is 572ci, 12-71, intercooler, Dart, big stellings, dominators, etc.
I would appreciate comments regarding performance from anyone running this cam in a similar combination.
Good choice...or..?
Thank you.

Bob's comments were all positive.
He thought a bit more lift would be the only change he would recommend, but agreed that for my use, (heavy boat, mostly cruising at 4200-4800, and no constant "hammer down" for all-out mph) the combination would work great.
Maximum torque at 5600-5800 sealed the deal.
No stud girdle required, no reversion.
Install at 114.

Do you mean max HP? Peak torqe is lower than HP.

Do you think that cam would be too big in a 540 n/a?
