    i see these on ebay alot. Just wondering what kind of performance/mpg gains I could expect by adding this to my rebuilt 350? Is it even possible to bolt it on...what else is involved?
    My truck is an 89 350 tbi
    thanks

    You'll see a slight gain in power and a noticable difference in torque. The intake should bolt to your stock heads with no problems. Just be sure to get an 87-92 intake to be compatible with the bolt pattern on your heads. I'm building new stand-alone TPI harnesses, so if you're looking for a good price on a harness, let me know.
