    1985 K20 350ci Engine Swap Choice

    Well, it looks like you live in Montana, so I dont think that emissions sticker is an issue, (its not an issue here in southern NM), so I would do the standard stuff. Aluminum single plane intake, good 4 barrel carburetor, nice valve covers, roller tip rocker arms, probably a good fitting set of...

    1985 K20 350ci Engine Swap Choice

    I am a do it yourselfer. I would pull out the 350 that is in there, myself, so I know how it all goes when I put it back together. Either rebuild the original or have somebody do it, then put it back together the way that it came apart, with the bolt on stuff that I wanted, with all new...

    Sm465 clutch fork has massive amount of play

    Something is probably bent. Maybe the fork. Or maybe the throwout bearing is riding on the pressure plate or something like that. There is a lot of pressure on the spring on the pedal mechanism under the dash that seems to bend things over time. It makes adjusting the clutch kind of tricky. That...

    GMC vs. CHEVROLET

    What, if anything is the difference between GMC and CHEVROLET trucks? When were they different, before they became the same? Why do they continue to make both? Just something to chat about that has to do with SQUARES.

    Compression test

    If its just a "yard dog" and sits in your yard most of the time, then you can just swap the heads out, but if you ever use it, then this would be a good opportunity to freshen the whole thing up. It sucks doing all that work changing heads and then it still runs like crap or has 10 lbs of oil...

    Window Felt Replacement

    I did mine a while back and don't remember them being too difficult, but definitely a challenge. I remember that there was a little tab on each one that you had to insert into a hole on the top of the door as a starting point. Yes the windows are tight and slow going up and down, but it seems...

    Making headers fit

    Wrong hole. Hopefully you didn't ruin those headers. If Hedman built those for a SBC and they fit that poorly, in the correct holes, I am sure they will exchange them.

    New 350HO issue

    Maybe it needs high octane gas. Sounds like a ping under acceleration.

    Delay wipers

    Sounds like a wiring harness/plug issue in the steering column. Those turn signal switches and modules are a PITA. Not much help here.

    Let's talk vehicle security...

    Nobody wants to reveal there "secret switch" locations! Thats like asking to publish the combination to the safe on the WORLD WIDE WEB!!

    New oilpan + one piece gasket help

    I had the same problem on the last engine that I built. I wound up using the old 4 piece style with no problems. The one piece wouldnt go into the ends. Maybe it was just the gasket that I had, it came on a blown up motor that I bought that had a chrome oil pan, (with a big hole in the side of...

    Transmission ID.

    Maybe Brewers. They are the Mopar transmission specialist.

    Brothers Truck is now Holley.com

    Haha, I thought he was talking about his brothers truck. I thought that Holley bought it and put it on its website.

    Normal operation of 4wd

    I just do it "just to be sure" at the end of the day, after using 4wd. Thanks.

    Normal operation of 4wd

    I suggest that you inspect and service the entire system. Make sure that the transfer case has enough of the correct type of fluid, maybe even drain it and put new Dexron type fluid. The linkage is pretty simple, make sure it is not bound up, etc. 2H to 4H can be shifted on the roll, but to get...

    Compression test

    There is a lot of variables there, but I just put together one that has "stock" pistons and large chamber heads and it has 115 lbs. of cranking pressure.

    Welcome from NM. We will take you in... if you show us some pictures of the old '70.

    Compression test

    I would pull out all of the spark plugs and do a complete dry test first for a base line then the same with the wet test.

    Holy Grail of Squarebodys

    Its missing the front grille, but looks like a nice truck. Is that a center bolt 350 engine?

    Correct timing and which vacuum port

    So, hook the vacuum line to the port that has vacuum at idle. The one that increases the idle speed when you plug it in, whatever carburetor you have. That is what is factory on all the stock GM carbureted motors that I have had.

    Correct timing and which vacuum port

    That is the vacuum accumulator. The vacuum advance canister is the cone shaped thing on the bottom of the distributor.

    What rpm should a 454 4speed

    Whatever feels good, around 900 or so. Maybe a little more if it has AC. Just my opinion.
