Im thinking on getting a core engine and rebuilding it over time for my 71 RR. Currently has a 383 but may go to 440 depending on what extras I would need to get. My 383 currently has AC. If I go with a 440 what off my 383 wont fit other than the intake manifold? Will my exhaust manifold height be the same? Actually 440's seem to be more readily available than 383's in this area as cores. Suggestions? Thanks
With all the stroker kits around today, why make work? You have a 383 in there right now, and everything works and fits right. From what I see, you can stroke a 383 up to 496 cubes. Then all your brackets and pumps and pullys all still fit. And A/C is awesome on a 71 RR. Throw a stroker kit from 440 Source, or Muscle Motors, or even Hughes, in it and have a killer street car that looks stock and tell everyone it's just a little 383.

I was in same situation as you. I needed to rebuild the original 383 in my RR and intended to build it up a little but keep it stock appearing.
Long story short I found a deal on a 440 and spent exactly the same as if I had rebuilt my 383.
I cleaned up the old 383 accessories (air cleaner, manifolds, etc) and put them on the 440. Even kept a 383 pie tin on it to fool the brand x guys.
I don't regret it for a second! Runs way better than the 383 and looks more original than the 383 when I bought it!

Most people cant tell an RB from a B anyway, even a Mopar eye has to look twice to be sure. A stroker kit from 440source is what, 1800 bucks? And you really should have the rods checked anyway, you can buy a 440 rebuild kit for like 600 and if your rods check out alright, you dont have to spend anything extra on machining. The 440 winds up cheaper than a stroker. Although a 451 will rev up quicker. I still say unless youre going for all out as much HP as you can get go with a 440. With stock rods parts wont be too much and 450 horse is easy.
