    Coversion from Carb to Tuned port injection - worth it?

     



    I have a Holley carb on my mildly build Small Block 355. I don't like it because it is too big for my application, and the fuel bowls drain when I am on angles offroad.

    I had planned to switch to a quadrajet carb, but I have come across a full TPI setup for $500 (yes it's checked good, 350 injections, and comes with everything I need including gaskets).

    Is it worth it? I will get better fuel economy, more response and driveability, no stalling on steep hills, and if I'm lucky, a few more HP.

    I ask because I just don't see spending $150 on a quadrajet, just to do the FI in a year or so. I would like to hear your opinions.

    Yes to driveability, but I bet you spend double that by the time it is installed and running. Especially if you don't have a wiring harness and computer yet. One place to look at is www.jimsperformance.com for good info.

    I've got an entire tpi setup laying around that came off an '86 Camaro with a 305. The car was running, though not real good. The car is getting a brand new LS engine and I don't need it. I'd sell you the whole works for less then half that including the computer. I don't have the wiring harness...

    I appreciate the offer, but I am planning to get a complete, tested system with proper chip and correct injections. Plus the wire harness is a huge deal.

    Yes but,

    My '86 TPI Z28 had to have the injectors floated every 4 months. It would start a sputterin' and missin' and crud ..... I don't really know why either, just FYI ...........

    TPI works really well,I have it on my 355.
    Make sure the fuel pump and tank are right.
