Super tuning car runs good shooting for great

That's good you got it straightened out. The decks on factory chrysler blocks are horrid. Unfortunately many shops don't take the time to really measure things and get them right unless there using something like a rotter machining center. I switched careers and half to farm out my machine work now instead of doing it myself. It's been a complete headache. I plan to start picking up equipment in the near future, may take several years to get everything I need but that's my plan.
I always thot Chrysler blocks were way closer to being right than chevys. I had two hemi`s and they were perfect, my 67 440 block only reqired .003 to make sure it wasn`t warped. the chevys I`ve had, took a bunch of everything to get right.
