Not a lot of big farm trucks around here, so I was wondering what else to look for. | | | | | Joined: Sep 2001 Posts: 29,270 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,270 |
Depends on the year.
In 1954, the 261 would have come as an RPO in 5000 and 6000 series trucks.
In 1960, various 60 series trucks might have come standard with a 261 (or a 283): C60, L60, T60, CLT60H, S62, S64, and S67.

I would think all Pontiac 261 would have hydraulic lifters.

The engine was in a 2 ton 1962 truck. Really worth the time searching for the engine. | | | | | Joined: Apr 2005 Posts: 122 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 122 | My 55 6500 dump has a 261.

I'm excited yet nervous as I near a time where I could possibly crank it up.

Only a military 302 and a couple of 270 Jimmies. Probably all sold by now. | | | | | Joined: Apr 2011 Posts: 181 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2011 Posts: 181 | There is a 261 block that has been recently checked advertised in the "Inliners.org" site. The heads can be obtained from many sources.
