Is there a specific reason you are looking at going with this hyd. roller cam? If its max power you are looking for I would go with a solid roller instead of the hyd. But anyway, if this were the EXACT ZZ502 cam and lifters, you would have to drill and tap the lifter galley for the lifter retainer setup due to the factory hyd lifter setup, which doesn't have connecting bars like aftermarket roller lifters. I also believe that the ZZ502 cam doesn't have a provision for a mechanical fuel pump, but you wouldn't need a 502 timing cover as the Gen V and VI big blocks have a different timing cover bolt pattern all together. This is all I can think of right now, maybe someone else will chime in with a response.
