Wanted: 261 Chevrolet engine

[chris vickery]

No issues with hijacking Hanno, I just know how these threads start of one place and end up another.
I do suppose that in NL and the rest of Europe, the GMC is predominantly found.
Here in North America we have the luxury of the big 3 automakers who built before and after the war., often using what was on hand and even continuing onwards later.
The Ford flathead is another example that was used before and well after the war with modifications and improvements from the factory. Thats what engineers do.

Hi Chris, et al:
I have just got my rebuilt 261 back from the engine shop. It is a complete overhaul bored to .030. No problems getting parts but rear main seals leaking seem to be an issue, so some shimming and gooping required to seal this engine. With respect to engine mounting mine ( 1958) does not have the holes at the front base where a 216 bolts to the front cross frame but rather has side mounts about 3 inches back from that location on either side. There is also tapped holes on either side of the block back about 10 inched from the front where you could put proper side mounts if needs be.
In my case this is going in a 13 cab CMP and I had hoped to use the heavier (synchro) tranny that came on the engine but it is longer than the CMP tranny so I may have to go no synchro.
Frame is sandblasted and painted, springs rebuilt ready to go in, just need time!! B.P.

Well I have a couple leads but like Bob C mentioned it looks like finding one will be a challenge and at best likely a rebuild.
In the meantime, looks like I might have a line on a running 235 for now.

Don't be shy Bob....star a new thread and show us your cab 13...... pleeeeze!!!!

You may be able to drill your front plate in situ for mounting in the CMP typical location...... have you changed the water pump yet for the extra clearance???/

Hi Bob P

Best solution I have found for excessive oil leakage for any of the Stovebolt Series engines is to speed sleeve the front and rear crank seal locations.

Cheaper and better fix than having the seal surfaces reground.

Cheers Phil

Seems like this is the archilles heel of the 216/235 series of engines, leaky front and rear mains.
Last one I worked on I had to do the same as Phil recommends along with new seals.

Hi Chris

I have installed speedy sleeves on the front of the crankshaft to over come wear grooves in the crankshaft where the new seall would rub BUT......tell me how did you install the speedy sleeve on the rear of the crankshaft...

I have a small leak on the rear of my rebuilt engine but so is the tranny, T case and every other joint..... I regard it as my truck marking it's territory.... never enough to affect the level of the lubricant contained.
