I only plan on sending the block in to get machined, my father owns a shop and is very experienced in building engines, but he's a chevy guy and refuses to help me with what I should get, on the other hand he will help me build the engine becuase he's my dad after all.
Sounds like your dad is doing you a favor by staying out of your parts decisions. As Dirty Harry once said 'A good man knows his limitations'.
You have come to probably the best place on the planet for sound, experienced Mopar information. Post your budget, desired power level, and intended use and you will get plenty of responses.
Good luck with your build.
