I seen a large truck in the wrecking yard, the guys told me it is a 56 Chevy truck and the motor ran dam good , too I know I could get it and the radiator for next to nothing. And since my last attempt for a good motor went to **** I thought this would be a better choice. But this a large truck and I don't know if its a 235 of something larger, I couldn't get close enough to the block to see the numbers because the truck sat so high.
I think it's a 261. Looks like the captains bars just above the starter.You can google for casting #s. Looks clean for it's age too.
You have a winner !! Chevie 261 Fourth picture shows two bars on the block just above the starter. Holy grail of early Chev motors. That can be your Christmas present. Cheers Rod
If you can get the casting numbers off the block and or the stamped numbers from just behind the distributor it would help. . Got knowledge on mine that way here with a bunch of other help.
I layed on the ground and there wasn't any #s on the lower front part of the block, so the only way is for me to clime in the motor from on top of the fender and hand down --- that's gonna ****. The truck ran and even has a PTO or something , there's another kinda like of drive line with a chain sprocket on the frame behind the cab. If it is a 261, is it the same lenth as a 216 or 235? Will it fit in to my 41 or 50?
they call these engine the stovebolt six....one of the best 6 cyl engines chevy ever did... sold the patterns to( oh! what a feeling TOYOTA.)...back in the 60's showed up as metric version in about 1972/1973 range rovers of toyota fame........
So this is it then, get it with no hesitation then.LOL The good thing about it is the owner of the yard is a friend of mine and we trade all the time, so its mine no matter what , I just got to get back with him and let him know if I wanted it or not.
The engine goes straight in where a 216 or235 mat have come from. External dimensions are the same, Extra cubes come from stroke and not bigger motor. Maybe a small issue with engine mounts, (sometimes). Uses same bell housing. You aint gonna get an easier swap. Ive got one in my 41Chev Pickup and one in my 52 Chev coupe.The head from a 235 is exactly the same as for 261.If the head has casting #848, then you have really cracked the jackpot. Patricks in Casa Grande Az is your best man. Dont even think again about Toyota, cause NOTHING is interchangable Good luck with it. Rod
O yea, I have the aluminum goodies , to the chrome goodies down to the dual carb to fenton split manifold to the PerTronix ignition for it , just needed a good motor. LOL
Thanks Im glad to get a lucky break once in a while, even tho I got a bad deal on the last motor, I guess mybe this is why.
Just an fyi. If you do get it, you will have to either move the radiator forward or put a "short" water pump and pulley on it to fit into the earlier cars. I found out the hard way...
looked at the pics again... this is a high capacity motor... heavt duty air cleaner, extra capacity oil filter can heavt generator... lots of good stuff here... man this sounds like a good deal for you... wanna sell it???kidding...your too far away... get it , set it up ,enjoy it.. it wont let you down... remember .....they dont make em like this anymore....keep it as close to stock as possible.......k
The cab looks saveable too. TCI make a new ch***is for those so you could build a new truck out of it. Has it got a ***le? I'd be a real shame to see that cab go to the crusher.
The inside is almost 100 percent original, I'm sure it wont be waisted, the owner even has some model A or T frames I think thats what are, with rear ends and some had trans and one had a motor but this stuff was rusted but some parts still usable. Don't know about a ***le, but even if it did, it might have been killed and then you'll need a salvage ***le. Im gonna try to get back there tommrow and take pisc and post them up for people to see, mybe someone would want or need this stuff.
The casting numbers IIRC are above the starter. That's the only positive way to ID it, but the captains bars are a good sign. There's an article in the tech section of Inliners.org on ID-ing a 261 A 261 is dimensionally the same as a 235. It shares most parts with a 235, but has bigger bores and a different stroke, I think
It's most likely a 261 pairing it with the size of truck and is definitely a pre 58' block. The later 261's 58' - 62' are preferred because of the full pressure oiling and 1/2" filter lines.
Actually Kevin the Toyota F engine started in the early 50s It looks like a Chevy but bore centers are larger. almost nothing enterchanges.
Just a little more on casting #'s, a block casting # ending in 340 or 813 should indicate a '57 261" block. The head casting # ending in 848 was a late '50's ('58-'62) 235 head, often used to up the comp. ratio about a 1/2 point or so for a little more power. A late '50's 261 head would usually end in 850, and earlier ones were something like 813 or 913, but I wasn't able to check that just now. If you do use the 235" 848 head on the 261", check that there are two "steam pocket" holes in the 261" head that have to be drilled in the 848 head. They are between the #3 and #4 cylinders. I gotta go to a meeting, can someone else go over the pin in or out for the full-flow oil conversion? Later, *****6
I take it you are not familar with the adapter plate that allows for mounting the 216 style pump on later engines eliminating the grief you are familiar with. More info here: http://pugetsoundvintagechevrolet.org/Programs/6 cylinder engines with photos.pdf More info on the coolant holes here: http://www.inliners.org/ubbthreads/...60&PHPSESSID=956e2ccbb99e62dfdab67a39d29d91ef
I believe that engine is a 58 or later model that has been swapped. Note the side engine mount location.
Definitely not. People confuse "full pressure" with "full flow". All 261s have a fully pressurized oiling system, but only some of them have a full flow filtering system.
The only way to tear a 261 up is to much RPM - Get it - Speed Parts for them are always on the market.
