1. you have to learn to keep your foot out of it.

2. overdrive transmission.

like A.J said thats all i could think of.
you could always convert it over to a drawthru turbo setup. it gave me better mpg and power.

how much does that setup run my carb is a holley 4160 would i need to swap it

 

[80regal717]

would i have to modify my headers to equipt a turbo

 

[dr_frankenstein]

it would require all of the turbo parts to make it work, whats your experiance to turbos? I think a carb turbo would be a poor beginners system.

I would say a 700 or 200 overdrive trans would be your best bet.... not to hard where its impossible, but it still requires some skill.

whats your experiance?

[mat231v6]

you can most likely get the whole set up for $200 on ebay. you have to use the exhaust manifolds to make it work. its real simple to do. BEFORE BLACK - Turbo Conversion
BEFORE BLACK - Blow-thru Turbo Conversion
see links for more help

a 5 speed would be a waste of time in this car. stock, the buick doesnt much like having a manual behind it. been there, done that.

could change them, but it wouldnt be cheaper than the O/D unit.

This is easy!
2bbl carb.
cheapest route to better MPG's with least amount of mod's,tools,time,heartache.

I'm sure the metering plate in your 4160 is set up for a small block v8.

he is right that is the best route. i swiched to the draw thru turbo myself but you would get the best mpgs on a 2bbl.

1) Which intake and carb?
2) What tranny?
3) What kind of driving are you doing?

My old NA set up got 20+ MPG. If you're getting 10 then you're either stomping on the gas a lot or have an issue with the carb and timing. Give a little more info on the car and we should be able to help you better.

(in School now) i can barely afford to drive it there

Welcome to my world... I am using a 4bbl Edel carb/intake on a N/A setup right now and my MPGs are about the same as a 350 SBC But I have a few modes on it and I drive fast too, so that`s kinda my fault. I`m in collage too, so I hear ya there... plus, I haven't worked a day since Nov '08, on unemployment(welcome to MI)

A light touch on the throttle is a good things guys. Pretend that you have an egg under the pedal and it will save you some money.

 

[80regal717]

does a pcv valve do anything for gas cuz mine didnt have any vacuum so i spliced it with my vacuum hose to my brakes bad idea its still kinda driveable

 

[charlief1]

PVC can be spliced that but it shouldn't cause an issue like you're having.
