Asked by wjm22400 Jan 29, 2017 at 06:33 PM about the Chevrolet Silverado 1500

Question type: Car Customization

I would like to know what some good upgrades on my 94 chevy would be
its a 5.7 350.

Im lookinfg for better mpg and a little more power and a nice purr.

I have heard of running headers into flowmaster super 10 and then through
a high flow cat to dual pipes is good for sound.

What else can I do?

Thanks for the help

I doubt that you would get any better gas mileage than you do now, but it sound like you want to do some. The exhaust would all be good, in-which you are talking, Holley makes a better TBI with bigger fuel injectors you could put on, and you could get a performance chip to install. But if you want to spend some money, then check this out, I built for my '95 Silverado,

You covered about 1/2 of what I put into that motor...It sits there at 400 hp. I just wish I would have put a 4-barrel fuel injected throttle body, with a stand alone computer on it when I had the money. Extra $2500 for that, probably why I didn't do it. lol.

If you have low gearing in the truck now, changing the gearing could add some MPG if that is your main concern.

What do I change the gearing to? also what type of K & N filter? Then for the last question if i change injectors and get a chip am I going to need to get a different transmission
