you better check with the guy's that made the cam ..you have to check for coil bind ..piston clearance..rocker centering ..pushrods and other stuff if you dont want things colliding ..the hot rod shop will have books on cams and how to set it up...you have a heck of a project in front of you ...514 sounds damm big ..what are you aiiming for ..can't you go back and exchange it ?? most cam manufactures want you happy ..to big is not gonna make you happy ..ask them an see what happens..

Gotta agree on this. Lots of work. You may also need different pistons with valve reliefs. The truck may not run as you plan too. To much cam can lower the vacuum amount below what is needed for the engine operation also. I would get it swapped.

No matter what, you need to verify that the valve train will operate properly without hitting pistons and such. If everything has the clearance, then get the system set up properly.
