    383 question

    I built a 383 (actually mine was 385) in the early 80's, before any of the kits were available for this. My machinist had the internals from a 400sbc that was in a boat, that had frozen and broken the block. We used the stock 400 5.57' rods, the 400 crank, .040 over cast replacement "rebuilder"...

    Putting A Chip In A TBI Truck

    Hey, that's good news! are you noticing better response and power over the original motor??? Just for giggles, I did the "ultimate tbi mods" and put a kit in my tbi over the weekend. I bought a parts truck last summer that has a stuck motor, but it had a tbi spacer, a "Tornado" air...

    Putting A Chip In A TBI Truck

    I didn't go back to see what Gavin's combo is, but I am going to be replacing the original 350 in my 94' K1500 with a 1999 vortec 350, and put my original tbi back on it. It will have the Chevy marine cam, and a bored (46mm) tbi on a GMPP carb intake, with an adaptor. EGR is required here. I...

    New Crate Vortec L31 into 94' Sierra 4X4. Any tips for the newbie???

    Thank you Gramps. I do plan to experiment a bit with the TBI, after its running and broken in. I have read some on what that requires. I may put a new Vortec fuel pump in while I'm doing the rest, then tweaking on the TBI as I go. Bottom end torque and economy are my goals. From my...

    New Crate Vortec L31 into 94' Sierra 4X4. Any tips for the newbie???

    Hi everyone. I know this has been done thousands of times, but I would like some input before I forge ahead and have to start reinventing the wheel! My 94' Sierra has @ 207K miles on it and is tired. It runs fine, but is weak. And the trans is definitely going south! But I will fix that...

    94’ TBI EGR swap

    I have a 94’ K1500 that’s about due for a new motor. My question is: Have any of you swapped an earlier 4 barrel intake and put the TBI back on? And if so, How or what did you use for an EGR valve? I’m wondering if I can use an intakeI’ve had great luck with in the past on my fresh motor. Thanks...
