V8 swap gas mileage

[lifted_xj]

I'm just curious what everyone with a swapped v8 is getting for gas mileage.

Not me...but I'm sure the V8 used (e.g. 302, 350) will make a difference. It won't be good.

Whatever the original vehicle it was in probably got better mileage because it was likely not pushing a brick.

I was getting between 14-15 on my Comanche with a carb'd Chevy 350. That was running 3.55's and 33's. Hoping to get 15 on the new setup since the engine is basically brand new with 4.10's and 38.5's. I'm also running 2.5" off the mufflers into 3" with a high flow cat, straight through muffler, and only the essentials on the engine (alt, ps, water pump).
