I don't really know which i should choose.

No the comp cam is identical but it is so close it would be hard to see any performance differences between the two. Both great marine engine cams

I think comps are cast cores?

Hardened steel billet with a cast distributor gear pressed on.

good point talking about cast cores.i would never use a hyd roller cam made from a cast core,espically in a marine application.

Are you looking at kits where the Comp Cams uses factory style dogbone lifters and the crane uses retrofit link style ?

Bang Bang 06-14-2019 02:55 PM

Yes.... comp cam refers his dog bone lifter for $218.
crane refers lifters for $880. they might be better, but do i really need them? Is there an improvement over the comp cam set???

how much lift can you put in motor??
i have isky cam 710 lift,,red ball series lifters (no needle bearings, was told the best market)about 1000$$for lifters

personally,, i would not want to pull a motor to change a cam. (unless its easy job..hahaha)

just had to pull my motors again to address and change water pump set up. dont ever want to pull motors again....!!!!!

Bang Bang 06-16-2019 01:14 PM

.710 is a lot lift....
i gave johnson lifters an email to get the right part number for my project, but did not get any response.
Lifters seems to be a neverending story in my build.
Perhaps i should take the comp cam set to come to an end.
