    2/4 to a 4/6 Question

    I currently have a 2/4 belltech kit on my truck. I do not have the original spring hangers that I took off to put on the drop hangers. Is there anyway to get the 4/6 and use the drop hangers. I really hate to spend $100+ each on new stock hangers. I didn’t pay that much for the whole 2/4 kit...

    NV3500 to 700r4 swap.

    I have a 91 scsb that currently is 350/nv3500. What all would I need to do this swap. I’m trying to just find a donor truck to do it that way. Would the computer need to be messed with?

    TBI Cam Question

    So I’m thinking about putting a cam in my 91 TBI 350. It’s my dd but my daily commute is only about 5 min. My question is, has anyone had experience with putting a cam in these trucks without a custom chip? If so which cam worked for you and did it make a difference. The truck has a good flowing...

    LC9 91 5speed swap

    The truck is a 91 rcsb with 350/nv3500. I have a tb to pan LC9, but unfortunately don’t have harness or pcm for it. What type of pcm do I need to be looking for. I’m deleting the DOD and VVT. So I don’t have to worry about those in the pcm. But it’s a gen 4 and is a 58x. What will I use from my...

    Carb Size

    I’m doing a carb swap on my 91 tbi 350. I’m getting the parts together and have a question about carb size. I would like to put a 650 on it, but have access to a 3310 750 vacuum secondary Holley and also a 450 cam Holley. The truck is a daily and is stock for the moment. It will later get a mild...

    TBI fuel pump question

    I do believe my fuel in my 1991 has gone out. I still have some things to check to make sure, but that is where the facts are pointing. Here is my question. I plan down the road to do a 5.3 swap. With that being said. Could I swap in a vortec pump or a walbro 255 and it run ok with the stock TBI...

    Nv3500 to 4l60e conversion?

    I have a 91 2wd scsb. It was born with a 5spd which I prefer, but my wife doesn't like driving it and wants me to put an auto in it. I would like to go 4l60e, but know that the 700r4 would be a lot simpler. I plan to do an ls swap in this truck as soon as it's financially feasible. What would be...

    LS Swap Trans Question

    Im planning and piecing together a swap for my 91. I plan to get a 99-02 engine so that I can just use cable throttle and less electronics to deal with. The truck is currently a 5 spd but I plan to go automatic with the swap. Would a 4l60e that matches the engine as far as year be better or a...

    88-93 Painted GMC Grille

    Does anybody have any pictures of the 88-93 gmc grilles that are painted. It's the composite headlight grille. I'm debating painting the chrome body color, but haven't been able to find any examples of it.

    Wheel Question

    I'm got a 91 c1500. Does anybody know of any 5 lug 16 or 17 inch factory wheels. I know our trucks didn't come with them, but are there any common pull offs that would work. Reason I'm asking is my neighbor is a GM mechanic and can get me free pulloff tires from the dealer. I know Jeep is the...

    96+ cam in TBI truck

    I've got a 91 GMC scsb. 350/5spd. I've come across a 98 350 short block with a rod knock and I'm curious if the cam and lifters out of it would be beneficial to my truck. I know the TBI cam is complete junk. Would swapping it over to the hyd. roller help any. I've been wanting to do a cam, but...

    Speedo Question

    I have a 91 c1500 with a 5spd. I'm about to swap out the 3.08 gear for a 3.73. What do I have to do to fix the speedometer after this swap. Is it just a plastic gear that has to be changed or is it electronic?

    91 350 Tbi running rough

    I've got a 91 c1500 350 5speed. It runs great going down the road and even idles good. My problem is when you take off like turning around in the driveway or sitting in traffic or pulling up in a drive thru. If you let the clutch out without giving it gas like you would pulling away from a stop...
