I have a fairly stock 83GT. I already have a newer and recently ran Edelbrock 750Cfm laying around. I dont want to spend money so, If this carb is rejetted and ran lean would it be ok to run? Or is it out of the question.

Im thinkin that tha carb is gonna be way too big for a stock 83.

you car will be drowning if you stick anything bigger than a 600cfm carb on there

I agree stick with a 600 vac secondary and youll be fine thats what I run on the 82 and its just right!

I really DO NOT want to spend money on another carb though. Carb guys, can I make this work with smaller jets and even a very lean fuel setting?

Dont think so... you'll just end up washing your cylinder walls down with gas an that is not a good thing... there is much more to a carb than the jets...

sell it so you dont have to spend much money. or maybe you can trade it straight up for a smaller one

It's a common misconception that a carb that is too big can be "jetted down" to work on a smaller engine or one that does not require that size carb. Without getting overly technical, jet size will not affect the amount of air that the carb flows.. Carbs work on air flow, if the carb is too big there will not be enough velocity (air speed) for the circuts to work properly. Sell it or trade it for a smaller carb.

This is exactly what i needed to know thanks. Anyone want to make a deal on an edelbrock 750cfm? Ran pretty recently.
