    Tach options

    I use the factory tach option. It was found in a K5 at a salvage yard. It looks like but obviously not digital odometer or anything.

    400 to 350

    Rather than making a new thread, I'll add on to this one I pulled the 400, swapped over the fuel pump, valve covers and motor mounts/clamshells. I haven't put the manifold on yet because I'm using that section with the leveler. My problem is that as I'm installing the new motor (350) is...

    400 to 350

    I think I've done it both times, with the most recent being with all RTV. I was removing and installing it on a monthly basis it felt like. Ah, that clear it up. I've seen the term around while researching but wasn't sure. Thanks.

    400 to 350

    Clamshells should be the motor mounts right? How many of them should I expect to find and will they be on the bottom of the motor? I intend on doing a lot of part swapping with it on the stand, since I put a bunch of 350 parts onto it. It's running headers so I shouldn't need to worry about...

    400 to 350

    I made a thread awhile ago looking for help regarding an issue I was having in my 400. I never officially figured out the issue, but I am sure it is a main bearing that went bad. Anyway, I've decided to swap it out and picked up a 70's 350 a few weeks ago. I've never done a motor swap...

    Ticking/Rattle on acceleration

    The knocking I'm experiencing has been happening for a few weeks. It was a rattle (like I had a piece of chain link hanging loose) and when I tried merging onto the highway, it had a fast pace knocking like in the video from inside the cab. It remained at the knock even as I let down into...

    Ticking/Rattle on acceleration

    I will look into the valve lash. It's something I haven't tried yet so it won't hurt. I haven't touched the vac. advance yet. That would be done by moving the vac. cylinder(?) on the distributor right? What is confusing me is that it began as a rattle when the truck was giving a lot of load (3/4...

    Ticking/Rattle on acceleration

    While it is disappointing, I'm not surprised. I've did a lot of research before I saw your post and was thinking the same thing. I don't know how the u-joints are but the sound comes from the firewall region so I don't think it would be them. I still have a scheduled visit to the shop that did...

    Ticking/Rattle on acceleration

    I looked at the flexplate a bit since I've had one crack before. I didn't see anything noticeable. It's fresh off the rebuild too so I assume the shop would have seen any cracks. The oil pressure gauge never worked either so you're probably right. I'm assuming this is only repairable by rebuild...

    Ticking/Rattle on acceleration

    So to update the situation: I installed new exhaust manifold gaskets earlier this week, a mechanic friend suggested an exhaust leak as the cause. That wasn't the issue I installed a new mechanical fuel pump yesterday morning because I saw a video with a similar sound and that was their...

    Ticking/Rattle on acceleration

    I've installed the new oil sending unit, and filled the oil up a little today. Last night I switched back to the manifold vacuum and I've found that the truck will actually idle at a higher RPM than it was when the shop switched it. After getting it back from the shop, I've noticed some other...

    Ticking/Rattle on acceleration

    I found that the oil sending unit next to the distributor is broken, cause the bell housing is covered in oil. I'm going to install a replacement tomorrow.

    Ticking/Rattle on acceleration

    I don't believe the timing was readjusted from before today, so it should have been about 9 degrees. They mentioned the piston rings or valves possibly being tired and causing the compression issues. I was lied to when I purchased the truck so I'm unsure of the mileage (was told it was freshly...

    Ticking/Rattle on acceleration

    Sorry for replying late, been busy with school and work. I took it to a shop and it got diagnosed as detonation issues. The shop report says "Reset base timing to 8* BTDC and reworked vacuum advance to ported vac. instead of manifold vacuum. Has blow by and low compression which may cause...

    Ticking/Rattle on acceleration

    When I give the truck gas in the mid range it has this rattle like sound, to me it sounds like a chain is hanging loose and whipping around. When you get into higher RPM (4-5k), it's a fast pace, and very loud tick. My girlfriend has also described the sound similar to water gurgling. Earlier...

    2WD to 4WD TH350

    I decided to replace my 4WD TH350 after it stopped working, and I found a 2WD TH350 from a mid 70's chevy truck. The seller said it's a long tail shaft trans. So my question is how possible is it to make the 2WD trans into a 4WD? If it's possible, what will I need to do? and could I use...

    TH350 issue

    Yes. It'll move through drive gears without doing anything.

    TH350 issue

    In December/January, my truck started to not move when I shifted it into gear unless I gave it a lot of gas. The worst instance was one night, it wouldn't move but would go in reverse fine. I would give it about 1/2 to 3/4 throttle and it would barely move forward and then slowly work its way to...
