Well i have a 97 Silverado(350) and was wondering what are some good starting off mods. I want to keep it as quiet as possible but fast as hell. I just installed an air intake. Any help would be much appreciated :smile: .

is it a vortec? probally a stupid question but im sure they make a supercharger for it. vortec or not

If its the stock engine its a Vortec. They came out in 96 with 250 hp, 335 lbs-tq. For 97, they got a hp bump to 255.

As for some mods, well you got a good start with the air intake. Just the usual bolt-ons will do (headers, exhaust, throttle body spacer,etc.).

If you want to go radical, you can do a cam swap, along with new roller rockers.

yea i wasnt sure what year they put the vortec in.
thx

Throttle body spacer, and a flowmaster 50 will do some good. The 50 isn't as loud as lower numbers. If your really extreme, a new set of exhaust headers will do you good. Consider a port tuner and computer chip.

Thanks guys for the responses.I have been doing some research and came up with this list: shorty headers, TB spacer, pulley, and bigger MAS. I want a good 300hp, would i be close the these mods?

I wouldn't do the headers unless your doing your exhaust. They'll still have the same amount of pressure through the same restrictive exhaust. Headers with a good catback exhaust, along with the other mods you listed will give you close to 280hp or so. I agree with Rbraczyk, a chip will give you even better HP.

i would change the gearing in your rearend, it doesnt had hp but it does effect acceleration and shit

...and the gearing in the front end if it is 4wd!!

The things you listed are good. I, as well, would do a full exhaust system and not just the headers. I agree on changing the chip too.

Thanks guys, i will keep you updated on my mods to come

Wait i have one more question. Are there any bolt on heads i can use, like LT1 heads off a camaro

Yeah. You can check out Edelbrock, I'm sure they make a set of heads for the truck.

I don't know about using LT-1 heads, but your Vortec and the LT-1 are both 2nd gen block designs.

If you upgrade your ring and pinion to a higher gear ratio it would give you better off the line power.
