    95 GMC C1500 with L29 454 and 4l80e

    I found the answer for the mess of pass through wires on this forum. Heat from a heat gun turns the block of wires into sticky goo. Let it sit a few minutes and the goo turns into putty. The wire separator is reusable and the wires don't have to be cut if you are needing to reuse them. Wear...

    95 GMC C1500 with L29 454 and 4l80e

    The more I look, the more hokey stuff I find. The shifter linkage is from a van (so was the 454 engine and trans). The cable comes out from the firewall and the cable gets all turned around to end up where its supposed to go. I saw on youtube where its supposed to route in the trans tunnel. The...

    95 GMC C1500 with L29 454 and 4l80e

    The painless l29 swap harness and the hacked up 95 engine harness are removed from the truck. The rectangle passthrough hole under the coolant bottle, the stuff inside the plastic housing is tough. I dont think its RTV, more like some specialty glue to bed the wires. I was able to carefully...

    Yes, this is not a "snap together" job. That's a minor hurdle.

    95 GMC C1500 with L29 454 and 4l80e

    I finally started working on this the last few weekends. The painless (painful) l29 swap harness is now removed and the factory harness is pretty hacked up too. I have a lead on another uncut 95 harness to start fresh and combine with the reworked swap harness. I ordered a 2002 Express van pcm...

    275/60/15 8" wheel backspace?

    1/2" or so too far out to clear the inner fender lip. Its OK as long as I dont go any lower. For $67 each from Jegs, its OK

    275/60/15 8" wheel backspace?

    4-1/4" backspace is not ideal on a 8 inch wide wheel even with a 4" drop in the rear . It needs to be around 4-3/4. With the 4" drop in the rear its OK with the inner lip tapped up. I knew better but the $67 each price and free shipping from Jegs was attractive. My other wheels were 3-1/2...

    275/60/15 8" wheel backspace?

    Ok good to know, I did search here but the only backspacing reference I could find was a recomendation for 5" on a 15x8 wheel with a 275 tire.

    275/60/15 8" wheel backspace?

    I have a 95 short bed 1500 that needs a lot of work. It has newer 275/60 15s in the rear. One in front wheel is cracked. The 10" rear wheels are in good shape but the wrong offset by a long shot, so they rub at times. I have found some steel 5x5 15x8 wheels with a 4-1/4 back spacing reasonable...

    95 GMC C1500 with L29 454 and 4l80e

    The wiring is a mess! I can fix it but I need to find a good wiring diagram for the 1995 year c1500. They took a painless wiring L29 harness and tried to hack it into the 95 harness. The Painless harness is pretty well documented by color and location. The fix is to strip out all both harnesses...

    95 GMC C1500 with L29 454 and 4l80e

    I wouldnt have any other transmission behind a 454. The 4l80e is just fine, for cruising or a trip to the drags. With a ten bolt, not sure the rear could take the abuse of a stick.

    95 GMC C1500 with L29 454 and 4l80e

    Thanks, but 95 and up had air bags. I would rather put an early wheel on it if I can find one in good shape. I like the look better and my airbag wire is already removed.

    95 GMC C1500 with L29 454 and 4l80e

    Can I put a 1988-1994 steering wheel on the 95? Its got a tiny 13" grant wheel that I am not in love with. I see where someone's already removed the air bag wire when they did this. I don't want an air back back but like OEM steering wheels better than the Grant.

    At some point, I may switch them. They seem to be the same style era as the paint. The old 90s style paint I am not crazy about either, but its not falling off. There is a lot on the truck I do not personally like, but there are more pressing issues.

    95 GMC C1500 with L29 454 and 4l80e

    Yes the struts work. I am not sure if I am going to keep that cover on there. Sort of hard to use the bed for anything big.

    95 GMC C1500 with L29 454 and 4l80e

    I purchased this today. Its got a lot of minor to medium bugs, but the price was right and I figured I might like the truck with a bit of TLC. Its a V6 manual truck that someone has dropped a 454 L29 and 4l80e but a lot of it is sloppy. One of my biggest complaints is they swapped in an auto...

    Rare special towing Cam, anyone bought a Oregon Cam Grinding, Inc. 1006?

    I used to order from Oregon cam grinding and Delta Cams a lot years ago. The part about "not having any records" That is normal for those two especially for Delta cams. Camshaft timing is CRITICAL, so I learned not to have sloppy people with no records grind my cams. I can tell you story after...

    Wow...saw my old 1994 GMC on facebook marketplace

    Nice! I tend not to get worked up with what owners do or don't do after selling. It's their problem now. I toss seat covers on my drivers to protect the upholstery also.

    Towing with sbc 350!!!

    I had a 5.7 1995 G30 van I used to tow a 6,000lb enclosed trailer up the mountains here in Oregon. It was tbi like yours. The ram jet cam woke it up along with vortec heads. The engine required tuning with tuner pro. It was a fun project. The engine was not that bad after I got done, it was the...

    Worth upgrading to GMT800?

    Thanks, the 8.1L with 3.73 is close to the towing power of the Vortec 7.4L with 4.10's. Towing a 6000 lb enclosed trailer. Even after a few weeks of using both, its a roll of the dice, I could keep or sell either one and be very happy. One stops and goes a little better, the other is much...

    Worth upgrading to GMT800?

    I figured out why the 8.1 felt so similar to the 7.4 when towing a trailer, power wise. The 8.1 has 3.73 and the 7.4 has 4.10. They are rated to pull the exact same weight trailer from the factory even. The 8.1 felt slightly better. I asked the seller before purchase and just assumed it was the...

    Worth upgrading to GMT800?

    Not going to tune either one at the moment. Whichever one I keep may get more done to it. It's not a big priority as they both pull well as is. I like switching up vehicles, so they both could be gone tomorrow if I find something else I like better. I just messed with the 350 van a lot because...
