Stock 360 Upgrades for Crusher Cuda?

Shouldn't be a problem. As your motor sits in the picture you posted, what will make or break the performance of it will be how the rings seal, and how the valves are sealing, and I'll throw in valve guides being in good shape.
Heads were replaced with remans shortly before the car was hit hard in the front. No damage to the crank pully. If the tapper isn't bad, then I may hone and re-ring it. I'm trying not to go down the rabbit hole of a complete rebuild right now, because in my history, that's where the project gets stalled. Just need a win with this project, and maybe it will push me to finish my Model A Hot Rod or make the Barracuda even better.
