    I got to thinking the other day (first mistake) about putting Tbi on my stepside but every thing I've read says you can't do it cuz the stock computer won't handle it ...... What about using a stock big block tbi setup ??? computer, harness, sensors, throttle body ETC. would it work ?? or am I missing something important??? I'd use my current intake (performer RPM airgap) with the adapter for the throttle body

    whats the motor in your step side? Most likely you will want a custom chip. I'm gonna guess you have a 383 or something similar. No factory computer would give you optimum performance for such a motor.

    It's a 377 destroke. 400 block ,350 crank ,6.0" rods vortec heads ,about 9.8 to 1 comp., crane energizer cam 272 duration .454 lift, full msd ignition ,Flowjunk headers, RPM airgap intake ,600cfm edelbrock carb ,jesel belt drive, J.E. flattop .040 over piston, and 2-1/2" exhaust with 12" glass packs . It works great here but when ever I drive to Tucson It runs way to lean to the point of pinging under normal accelaration and dieseling when I shut it off I have to retard the timing alot to get it to stop pinging or at least not as bad and richen up the carb quite a bit With TBI I wouldn't have to mess with it . It's not as big a deal an more now that I have my 86 K20 but I'd still like to take this thing on some more road trips once I get it fixed

    you should read in the truckin mags they usally have good tech stuff in them bout doing swaps such as this/ Yes most of the trucks in there are 2wd and lowered/ Yes some of them look good/ Yes they are almost all chevys in there b/c chevys kick arse. b/c most are chevys with TBI or TPI they have a lot of upgrades for them and computer mods and whatnot check it out.

    You can do anything you want. Burning a custom chip would be a necessity though, at least for it to run at maximum potential.

    To be honest, I don't know who provides this stuff. Perhaps check someplace like www.thirdgen.org and see if they have links, or forums that cover this stuff.

    I'm going to get into burning the chips myself, check out winALDL for yourself. Lets you interface with the ECM, then you buy the PROM burning stuff (looks like you can do it for under $200) and go to town. It takes a bit to get the PROM's "right", so multiple tries seem to be the norm before it's perfect. Which makes me think that buying "custom" PROM's online isn't the best approach. IMO
