I'm so excited - I recently picked up another good 261 (complete with the truck its in, original and un-molested). I posted on here a few years ago about TWO of them I had acquired - one in a '51 6100 and another I took out of a '55 6100. I ended up locating the original owner's family of the '51 and sold the truck back to them and then sold the other 261 a month later because I felt like I would never have a use for it. Boy was I wrong. I wish I had kept it. I'm planning to put this other one in my '50 4100 after I freshen it up. I need to post some more pics of my '50. Maybe I can remember to do that sometime this week.
1950 4100 - unrestored and driven weekly for almost no reason at all.
Do you know what year 261s were first built? My 261 is an early 1950s. It uses a short water-pump & no bars on the block. Do you know if early 50s 261s has a cast or steel distributor gear, or year they may had changed if ever?

Yea, I had this motor built back in 2005. I let it sit on the stand for all those years, I just put it in my 39 two door sedan. It has the original cam, but some time back I purchased a NOS distributor. The box disappeared & I don't remember what year dist. but I think it's late 50s/early 60s. I have started the motor a few times but not ran it yet. not knowing if the cam/dist material are same has wore heavy on my mind. Rebuilding the motor, I had a 1962 235 head machined to fit, & It's now a full pressure oil system. Electronic ignition with fenten two carb intake & fenten exhaust. It should be a fun motor to run.

Yes I had the head drilled to match the block water passages. Maybe I'm using the wrong word but like the 235 & 216 blocks, The oil still had a bypass. Only a percentage of the oil went through an oil canister mounted on the manifold. By adding a block in the oil gallery, diverting all the oil, using larger hoses out & into a spin-on type filter, all the oil gets filtered. It's been years now, I don't remember if it was Patrick's or Langdon's Stovebolt 6, I believe Landon had an article on building a 261 for performance. It's all over my head so I had a local engine shop build the long block.

If you are referring to the oil filtration systems, the 1958-1963 261 had the capability to be set up with a full-flow oil filtration system. Yes, 1/2" NPT lines (two rigid metal tubes and two flexible hoses) were used. This setup was not a spin-on type filter (like moder filters) - it was a paper cartridge inside a metal canister.
Just to complicate things, the 1958-1963 261s could also be set up with a by-pass oil filtration system (or, no oil filtration system).
216s, 235s, and 1954-1957 261s had only an optional by-pass oil filtration system.
It is possible to use a modern spin-on filter-head (like modern oil filters) on the full-flow 261s. I have done that on the 1960 261 that is in my 1954 Suburban.
I'm use an oldschool Toilet paper filter 1950s Bee-Hive spin-on canister. There is a photo of my 261 in my photobucket. The wrong side of the motor, but I do see the oil canister laying under the motor on the motor stand. "lower Right in the photo". I had to go full screen to see it.

I have not got to the dash yet on my COE project, but I'm sure modern gages will be no problem finding for your 1937 truck. I'm leaning toward Changing out my dash with something more classy? I like the front look's of 1959 & 1963 Chevy car dashes?

This 261 that I have came out of a '58 C60 Viking. The seller had it advertised as a '59, but it turns out the truck is a '58 model. I am certain the engine is original.

I will need to go out @ check, but it's a short water-pump block. But no II bars on block. So I would expect it's a very early model. I know it's a 261, it has more water ports & 3" pistons.
