whos runnin a carbeurated 350.......

[micus]

hey guys, well i just bought my first vehicle, 1967 chevy short box fleet side, and its got a 350 in it, carbeurated, its an auto tranny, but its got an edelbrock 600cfm carb, headers, to straight pipes with glass packs on the pipes to make em legal, and a performance cam on it, im just wondering what kind of gas milege i can expect from this truck, i kno its not gonna be pretty, but im just curious as to what other ppl with a similar setup to mine are getting for fuel economy,


also, since this is my first truck/car ever, i have no prior driving knowledge so when i do drive it i will have nothing to base weathers its fast or not on, so id also like to kno, do u think it will be fast? like fast enough to be abel to pull up beside a civic and not worry about it beating me fast?

You didn't say tonnage, but being that its a short fleet, I'll guess half ton 2WD. Expect 11-12 if you're good at keeping your foot out of the gas, 8-10 if you have a heavy foot. You also didn't state the transmission or gears, if you have 3.07's you can probably get away with some pretty descent mileage (for a truck) where as 4.56's will get you off the line fast but limit your top end and kill your mileage.

If you want to make a descent sized dent in that mileage, I would highly recommend an overdrive transmission instead of what your truck currently has (probably an SM465 if a manual or TH350 if automatic). That and fuel injection would also be a wise idea. Having put TBI on my '72 Cheyenne/20, I really really really hate carbs and don't ever think I'll go back. Next summer (when I have money) I'm going after a set of aluminum heads and an LT1 intake.

Any chevy truck owner that can't hold their own against a riced honda civic should be shot and dumped in a shallow grave.

That said, if your truck has been modified it should do descent against the hondas, but racing stoplight to stoplight your problem will be hooking up - if your truck doesn't have some sort of positraction or locker in the rear, you will have a difficult time (at least with stock width tires) getting proper traction to put your modified engine's power to the ground.

ok im pretty sure the transmission is a turbo 350, or 400, i have no idea about gears, it also has an aftermarket ignition, which is blue, , im not sure who makes it,

my truck is in a barn with no electricity in it, and weve had but loads of snow lately, so i really havent been able to do any work on it, but when i do, ill fill u all in on the specs of the truck, and maybe take a few pics while im at it, anyway, thanks for the reply,

A 600 isnt a huge carb so but with a non-overdrive tranny i wouldnt expect it to get great mpg if you drive it on the highway but it depends on the gear. I also wouldnt expect it to be very fast, the truck is heavy, but you should be able to take most riced-out civics. If you do lose, dont worry, your truck will always be cooler than a civic.

geeze who worries about gas millage any more haha. its no race truck but it will be alright against them little ricers. like greenbuggy said traction will be ur biggest issue.

[Myrmidon]

Traction ceases to be an issue when one applies 12" wide street radials to the back of the vehicle... but then you have to start worrying about your back glass, or more appropriately, not letting your head go through it on launch!

Let' see some pics of that truck, eh?
