    Putting a gas 350 in a 6.2 diesel frame, quick input please.

    The 6.2L uses the same engine mounts as the SBC. Should be a direct bolt-in, much as I hate seeing a 6.2L truck adulterated with a gasser. :oops: :p I put a 6.2L in a Scout II years (decades) ago, and used SBC mounts.

    700R4 no engagement any gear, ATF over-full

    Thanks... Was kinda hoping it was the torque converter and the trans was OK, especially since it only has around 75K since the last rebuild. I may look for a used transmission just to get the truck back on the road, then rebuild this one myself and put it back in. It's going to take time to...

    700R4 no engagement any gear, ATF over-full

    Finally getting back to this after way too long... :oops: Need to get this thing back on the road before too much more time passes. I got a pressure gauge kit and got some numbers: P-N-D-3 70 psi 2-1 170-180 psi R 110-115 psi FSM says to check pressures at 1000 RPM, but pressures didn't...

    Fuel change over valve Vs twin electric pumps

    No reason it wouldn't work, but you'd want to make sure the pumps have check valves to prevent backflow. And of course, you'd have to deal with the fuel return lines. The fuel return can go just to one tank. Use that tank first, then when you switch, a lot of the fuel will go to the first...

    Tire pressure

    Unless I'm misunderstanding you, it seems like you may be thinking backwards. More pressure will make a rougher ride and more impact on bumps. If you want to soften the ride, you want less pressure, but the problem with that is those low-profile tires. When there's that little between the...

    700R4 no engagement any gear, ATF over-full

    Thanks for the reply. I don't have a way to do a line pressure test, but when it happened I did feel the cooler lines to see if it was circulating fluid. The cooler's input was much warmer than the output, so apparently fluid is circulating. I brought it home today. The transmission worked...

    700R4 no engagement any gear, ATF over-full

    Hi all, 700R4 in my '83 Suburban, was rebuilt around 75K miles ago and has been trouble-free, except for an occasionally sticking throttle valve. Until today. I drove a half hour, it briefly disengaged while driving at low speed. I stopped and checked the ATF, and it was over a quart above...

    Fuel filter puzzle

    It's tiny, and 15 GPH is going to restrict fuel flow at high power, even when the element is new. And I don't really like mission-critical parts being made of plastic of unknown quality and composition that may or may not stand up to under-hood conditions. And it's not a standard-size element...

    Fuel filter puzzle

    My '83 has a factory spin-on primary filter/water separator, which I'm glad to have, considering all the problems I've heard of with the box filter. If I had a box filter, I'd change it to a spin-on. I wasn't aware the box filter had a heater, but I live in Idaho and have never needed one. I...

    Where to find transmission lines

    LMC Truck lists the lines for the diesel. https://www.lmctruck.com/mechanical/drivetrain/cc-1973-87-pre-bent-transmission-lines If that doesn't work out, as has been mentioned, it would be simple to get a cheap flaring kit and tubing bender, and make them yourself.

    Bad alternator bearings

    I know the thread is a bit old, and I didn't read through the whole thing, so someone may already have suggested this, but just in case... It's really easy to replace the bearings in an alternator. So if you have an alternator that's otherwise good, it makes sense to save a lot of money and...

    "Oldsmobile Diesel" Conversion to gas

    I did a lot of research on the 350 diesel before buying one. Its reputation is a lot worse than the reality. Its biggest problem is caused by GM's decision not to use a water separator, because they didn't want drivers to have to think about the fact that it's a diesel any more than necessary...

    Where to find transmission lines

    Another option would be to use transmission cooler hose. If you have old hard lines with good ends, you can cut those off leaving a couple inches, or the bend plus a couple inches, and use those instead of buying hose nipples/barbs. I always double up the hose clamps when doing that, just as...

    Barn find 6.2 precautionary measures

    Do you know, or can you find out, why it was left to sit 20 years ago? If there was some kind of problem, that would be the place to start. Otherwise, here's what I'd do: I'd recommend leaving the injectors & lines alone unless you know there's a problem there. Put batteries in it and bump...

    Any tricks to getting your SB doors to close easier?

    I did a couple of mine with PEX. Works great, but you have to remove the striker to get the PEX on, then make sure it's adjusted correctly when you reinstall. So I did a couple more with chunks cut from an old 1/2" garden hose. Works just as well. It probably won't last as long, but so far...
