Power Adders

I have an 87 GMC and I would like to know if there are any cheap power adders i can do. The truck is a 350 and it has TBI too.

I already have an K@N filter and a cat back exhaust.

what rear end gears ya got? that makes all the difference in the world

i just went from factory 3.08's in mine this week, to 3.42 posi, and it was night and day on my 87

you might also check out www.tbichips.com (at least i think thats the website)

oh, almost forgot, also check out www.thirdgen.org those camaro guys got there crap together, theres a whole section on how to get your tbi's to run like a slapped cat

thats the truth.. i had big tires and 2.73 gears.. and it wouldnt get out of its own way.. swapped to 3.42s and it moves right along.. gear ratio swaps make all the difference in the world. if your looking for speed, id try to find a 3.73

Re: Power Adders

x2 on the nitrous. A small shot can be done on the cheap without any major modifications. Just be warned that the juice will be addicting, so on down the road be prepared to start budgeting in major component and fuel system upgrades, because you will want to increase the shot eventually. Here's some info that may help........................

Re: Power Adders

i figure you would be better building a motor that is set up for juice and THEN spraying it then the other way around..
