My bad, I thought you mentioned in another post that you were thinking of doing some port work...
If you're happy with the cam you have now, switching to a hydraulic roller will be a cake walk....

I want to polish the intake and water pump maybe even the valve covers (those can wait till engine is back together) I will give Comp Cams a call and pick some brains there.
Been thinking for a long time about a solid roller again will talk to the cam people.

I would ask the guy on the other end of the phone how many BBF's he has built. It's easy for the "tech guys" to look in their catalog and read the descriptions, but they may not be familiar with that particular engine's pros/cons.
As an engine builder, I'd be happy to make a recommendation....I build a lot of big block Fords.

468.3 cubes, but you'll run out of breath with a 625 afb.
Would be a good street combo, topping out at about 5000 rpm, would be better off with a 750-850 carb.
