hey i am looking at purchasing a 1993 camaro with a 1997 lt4 383 engine with a 6speed manual transmision. i am curious what kind of gas mileage i can get on highway and city? the engine is newer but the car has about 150,000 miles on it. please help me out.

if its 383 im guessing its modded. Depends on what is done to it. Have you asked the seller what he's been getting?

 

no i have not. but i intend on doing that. but what it is pretty much is a 350 with a new cam that gives it a 4 inch stroke i believe which makes it a 383.

 

It's still a 350. The seller sounds a bit shady...

 

Cam will not change the stroke of the engine nor change the displacement. Do you mean crankshaft?

 

isnt a typical 383 4.030 bore and 3.750 stroke? Either way i would just ask the seller what he has been getting.

 

sbc, yes. They were also a 4.25 bore and 3.4 (approx) stroke in Mopars

to the OP, both of your posts seem as if you are new to this. I would bring along a parent or uncle because you don't get to 383 CID on an sbc with a camshaft

Also, if you are looking for economy you are looking at the wrong vehicles

 

yes i meant crant shaft. excuse me. and i am very new to this my dad is an expert on cars i am not i am only learning so if i make mistakes dont judge please just help me out and i believe its a crankshaft with a 3.75 inch stoke.
and yes my dads been checking the car out.
also i dont have much problem with money at the moment im 17 making plenty of money for my age. so gas mileage wont be a huge issue as more of an annoyance.
so i am just curios what kind of gas mileage im looking forward to i have heard from people with the 383 they get from 15-25. thats personally hard to believe, but could be true

 

yes that is the range of mpg. i get at worst 15 and at best 22mpg with the build and gears i have now. stock i have gotten up to 28 highway and thats with a auto. manual trans will do a tad better. what gear ratio is the rear end, that will also effect mpg. going from 323 to 373 i lost 5 mpg

 

make sure you see the receipts for the parts i could put a car on craigslist and say its a 383 all day when really its just a factory lt1 also as far as fuel economy a lot depends on what cam what injectors the tune on the computer how heavy your foot is ect
