sbc 383 expected gas mileage?
Ive got a 1987 camaro irocz with a swapped in 383. Ita got a 600 cfm eldebrock carb and is running a t5 tranny with a stock rearend which I believe are 3.23's. I could be wrong. I was just wondering what I could expect for city/hwy driving if i drive it nice not getting into it very often
Thanks for your time

city: 12-14
highway: 15-20
just a guess, i'm probably off. It's not a hard thing to figure out though, next time you're at the pump.

that wouldnt work for me, i dont have cruise and with 4.10's it sucks on the hwy. i built the car to go,and be fun to cruise around in, not get good mileage. that was kind of my point, you put a 383 in it now you are worried how much fuel you are going to use after the fact?

14mpg combined city/highway. Just driving in town nets me around 10-12.

Re: sbc 383 expected gas mileage?
3.73's with a 700r4 is going to be alot different than mine, i got no lockup and 1 to 1 third. its about 3500 at 60. i wish i had built the 700 in hind sight but i traded a guy for my th400 which i didnt think i was going to have to build significantly for my engine. i was wrong. to the OP if the t5 doenst hold up dont get a turbo 350 or 400, get something to retain your OD if you care about mileage
i would guesstimate in the 10-14 range for mine but like i said i dont take it easy and take back roads because highways are not very comfortable rpm for cruising
