500EFI cam equivelent
 
Did a search but most threads are older. Now that Crane is no longer, what camshaft the closest to the 500EFI cam? Been searching and figured it may be better to ask here as it could take hours!

Each of Comp Cams Extreme Marine EFI cams are close copies of the Merc blue motors 3 cams.
look for the one near 230,236 at .050” 114 lsa and .610 or so lift.

Thanks Scott. I'll look again but the Comp Cams website isn't very user friendly. You have to click on each cam to see the lift and most of the cams I saw at the 230/236 range had lift in the mid .5 range.

This is one I found with a little more duration and overlap.

Okay, thanks. They have close copies of the 731 and 741 cams, but not the ‘in-between’ 500EFI one.

I looked at EVERY Gen VI cam on Comp's site and didn't see the 2 Griff posted. Maybe they are special grinds for CP and Hardin?

Those 2 are there.
Again, Comp Cam Extreme Marine EFI.

Not just the Comp Cam Extreme Marine
