What are you all getting MPG wise on a 383 shortblock with heads, nice cam and intake?

Shouldn't be too bad with a good tune and the right set-up. But if you bought a Camaro.... you're not too worried about gas mileage. Just my .02

Going from a 350 to a 383 should not be that big of a difference but to give you a better idea of what to expect we are going to need to know what kinda transmission and gears your going to be running. Those will effect the MPG's more then just going from a LS1 to a 383

I doubt it will be much difference than any other heads/cam stock cube LS1.

It will depend on the combo and tune really.

What are the other mods?

I think he is trying to see what other people are getting with those mods.

I'd guess they'd be comparable to a standard stroke 346 with the same mods. Maybe 1-2 less, but that's a guess.
