    SM465: Difference between 2wd and 4wd

    I have a 1988 C30 with SM465, 2wd. Something's broken inside and I have a chance to pickup another SM465, but it came out of a 1987 4WD K series. Research indicates that while the later versions each had a 35 spline output shaft, the 4WD version is longer. Can someone confirm whether or not I...

    Painting plastic parts

    I have never had any success painting plastic parts. I have followed the guidance found everywhere: scuff sand, clean with grease remover, prep with adhesion promoter, etc. and there are always portions that just don’t take the paint just right. I guess it doesn’t help that I was trying to paint...

    454 original value add for a square body

    Did for me, but mine's a tow rig, so the added torque ought to be meaningful.

    Squarebody Holy Grail? Hmmm... maybe a 454, SM465 1 ton dually with an 8 ton crane on the back-

    No gas to carb

    Vapor lock is caused by the fuel in the lines turning turn to vapor because of excessive heat, essentially boiling it. This happens when you may have the line too close to a header, perhaps; but that's not what's happening here, because you're not getting fuel under any circumstances. An engine...

    Quadrajet from hell will not give me peace

    I'm in a G-body group for my '87 El Camino, which came stock with a 305 with a Rochester Quad. I have seen many people comment that Mountain Man Fuel Systems is the guy to send your Quadrajet to for a professional rebuild: https://www.mountainmanfuelsystemsllc.com/

    SM465 / Clutch

    Turbo4whl, thanks. I haven't installed any clutch parts other than the master and slave cylinders, and I don't know how old or worn any of the rest is. I actually have begun to think the clutch is probably OK, because I can shift into and start from a dead stop in granny, 1 or 2, it just won't...

    SM465 / Clutch

    Thanks. I feel better about the slave cylinder travel now, i appreciate you verifying on yours. I verified that the plunger does move the PTO cable which moves a lever on the side of the PTO, but of course I don't know what's actually happening inside. And I don't have a spare plate cover...

    SM465 / Clutch

    So, my new to me 1988 1 ton with a Holmes wrecker body on her, and shifting issues continue. Here's what it's doing, and here's what I've done so far: At rest, you can put it in any gear, however once moving, when it's time to upshift the stick doesn't move, like it's locked in place. Not...

    So, what's this emblem signify?

    I have these on my C30 tow truck. Looks like a teepee or tent?

    '88 Tow Truck Clutch issues

    OK. Had some time to get back in it tonight. Was able to align the forks and get the shifter back in, can find the gears in each position. Test drive, still doesn't want to shift once up to speed. So, my regular mechanic actually still uses his squarebody tow truck at his shop (same tranny)...

    '88 Tow Truck Clutch issues

    OK, Just got the truck, 454 SM465 tranny. Will not shift, shifter seems locked in place. I've done 2 things: 1, drained and replaced tranny gear oil with Sta-Lube 85W90 GL-4 gear oil; 2, replaced and bled clutch master cylinder and slave cylinder. Suspected MC / SC thinking it's defective and...

    New to the site from NC

    I'm over in the Ghent neighborhood. Can't miss a tow truck in the driveway, though some of my neighbors might want to. That woodwork in your Suburban looks a lot like a Mark III conversion, like they had been doing for the G20 vans for years.

    New to the site from NC

    Welcome from another new member also from New Bern. I'm working on an 88 1 ton dually with a wrecker bed that I hauled home from Durham a week ago.

    SM465 Gear Oil

    So, back to the '88 tow truck. I described in my earlier post that the ol' girl wouldn't shift (SM465) during my test drive. At rest, you can put it in any gear, however once moving, when it's time to upshift the stick doesn't move, like it's locked in place. Not grinding, just won't move. Once...
