Hummm, a 502 would be nice, since your already replacing the engine anyways.

It is an easy swap. Everything is design to be a direct bolt in, including my old headers. The only difference I found was the bolt holes on the front of the engine were one size larger. I had to drill out some of the accessory brackets, but no big deal. The huge advantage of going with a 502 is that you get the GEN VI block, which has roller lifters, and significant changes made in the oil delivery paths. This made the engine tons more reliable. The 502 is bullet proof and is designed to scream all day long if you want to. Gobs of torque and effortless acceleration.
If you plan to keep the coach, its a no brainer. Stock 454 is not really compatible with modern oils.
