Can you tell what color the block is?

Bucky
Well, maybe not so much. You could almost pick your favorite. But maybe originally red???

Also, there's a huge stumble when the throttle is pressed. I thing I need an accelerator pump. I don't want rebuild the carb, it runs great....on jack stands, in the driveway.
Any suggestion on where i can get the pump for this carb. believe it's a Carter, rebuilt by Holley at some point, according to the sticker on it.

You're doing good with the uploading of pictures. But I can't tell from that shot what T-case it might be. Appears to be missing most of the parking brake components.

I would say red too. That puts it 61-later.

Mopar used Silver, Gold, Turquoise in other years & applications.

I'll dig into it a lot more in the weeks to come, and some better shots.
Thanks

Those engines mostly came with Carter BBD ( Ball-ball dual) but I have seen Strombergs. I will look more closely at the pictures in the upcoming days.

Didn’t the earlier poly have a third bolt near the middle of the valve cover also?
yes some did.

Mostly because curiosity killed the cat. What year did they go to two bolt covers?

I'd like to replace the thermostat. What make, model truck is going to have this engine, so I can find parts.

The rake on this Jeep cracks me up. That's with extended shackles in the front to try and level it out. Guess this Poly is a bit heavier than the stock engine.

Thanks again.

I have seen 59-later with 2 bolt valve covers. But keep in mind there were dozens of different displacement V8 engines used by Chrysler Corp in the 1950s, some Hemi, some poly, some wedge. I'm not always certain of exactly what engine is in any given picture.

For ordering a thermostat or other parts I would try to use 1962 D100 as the basis.

I'll give '62 D100 a shot.
Here are some pics of the trany. Any thoughts on what it might be? The shifter cover is steel.

Thanks again.

That tranny and the transfer case shifter are not factory sweptline issue.

What could the trany T-case combo be? Since it's mated to the 318.

Seems like the next step for me is to get some casting numbers off the tranny and T-case.

I'm not familiar with the Dodge issue parts prior to 61 so I can't rule that out.
But, that bell is not sweptline era either!

Check with a magnet to see if the bell is aluminum. Does the clutch have a mechanical linkage?

It appears to be mechanical & approached from the REAR. As PwrWgnDrvr stated the bell doesn't resemble anything from a 61-68 TRUCK.
Now I am wondering if the engine & bellhousing are from an early 60's CAR & mated to an oddball 3 speed truck transmission. Unlikely that someone could cobble that together though.

Or as he mentioned, pre 1961 Truck.

Looks too archaic to be 69 & later.

I had an aluminum bell on an LA318 that resembled your photo. If I recall correctly, it came off a 70s vintage Challenger.
That's why I mentioned the magnet test.

If you do take off the trans, do check the runout on that bell. They can warp. I torqued one to the point that it needed the offset dowels to recenter the A833 trans I had. But gad that Dart wagon sleeper was fun!

I've been out for a few days. Just before I left, a buddy stopped 'cause he saw the Jeep in the driveway. He took one look at the tranny and said, that's a T-90. Told me where to look and sure enough it is. He also said the T-case is a Dana 18, but I haven't confirmed that with casting numbers. It likely is.

Bell housing is steel. My friend also did not know what the bell housing was. It is mated to the engine without an adopter.
The flywheel cover is missing, and I was hoping to replace that. So ID'ing the bell housing would still be helpful.

Thanks.
