Can you tell if this is a 292 ?

Trying to order some parts for my sons new 68 and I’m not close enough to check it out.
Thanks

SPID shows it came with a 292.

Re: Can you tell if this is a 292 ?

Are the motor mounts staggered on a 292 as opposed to a 194/230/250 which are across from each other?

Re: Can you tell if this is a 292 ?

292 side covers are 6 inches tall, all others are 4 inches tall....

that one looks like a 292.

Here I am. I had school yesterday. [24 hours of State-required EMT Refresher lectures, then practicals and tests].

Anyway, the ''tell'' is the taller side lifter cover plates.
Also fuel pump is midline, not forward.
Passenger side motor mount is forward.
Above mount also different from Driver side. [230, 250'S are same both sides]
L-25 [292 L6's RPO #] sits taller, so there's less headroom under the arch of the firewall.
SPID may state ''L-25'' and/or ''292 cu in'' in options.
The water pump has more outlets than a 250's.
Whole block is a couple, three inches taller.
Oil pan takes a full 6 quarts.
Heavy duty trucks had 3 studs on the exhaust manifold donut.
Usually WON'T have Power Steering or A/C. Majority of L-25s were in fleet work trucks. No frills.
Dress numbers stamped in block behind distributor mount may end in UH or XAE.
Referred to as ''HD-TD'' by Leo Santucci, author of ''Chevrolet Inline Six Cylinder Power Manual.'' Meaning heavy duty - tall deck. He referred to the 230/250 blocks as ''STD - LD'' for Standard duty - low deck. His reason for the terms was that after boring-out to .030, .040, .060 - over, the stock displacement volume numbers were no longer valid as a type identifier. A .030-over block is now at 296 CuIn, and .060 is a 301.
OP's carb looks like a Rochester Monojet. The 250 Monojet would look identical from the outside. I don't remember much about the single bbl carb. I went Four Barrel over 40 years ago.
Hope this helps...

Surely looks like one, tall 6" side covers, along with fuel pump mounted behind right motor are dead giveaways. The hose below the top radiator hose pictured here is a 292 giveaway also.

Re: Can you tell if this is a 292 ?

Here are pictures you might want to keep on file.
I borrowed the pic of the 292 from a forum page somewhere and added the text. So it’s not my engine. The other 2 pics are/were my engines.

Re: Can you tell if this is a 292 ?

Nice 292. It's a '63 to '66 vintage engine, going by the color [Alpine Green], PCV routing, and the upper radiator hose/thermostat housing.
Do you have pix of the 292 piston tops?
Might also mention that 292 pistons have 4 rings, not 3 like the 230/250 series.

Re: Can you tell if this is a 292 ?

OK. Nice pix anyway.
I have 3 292s. One running in my '68 Stepside, it's the OEM block that was in my Orange truck when I bought it in 1973. In '77, we rebuilt another 292 from a '67 Forest Service Long Stepside. I ran than engine for 25 years and 250.000 mile. Started a rebuild on the '68 block in 2002 and was on the road by 2005.
Also picked up a model year '63 292 from a guy at Checker Auto. I've been using that one for parts, but I might rebuild it someday. It came in that dragon snot green but with an old Chevy Blue valve cover. PO had bought it just for the scripted CHEVROLET letters on top, and replaced it with a non-scripted cover.

You could always sell it back to me. I bought a 1967 C10 with a 250, I would like to put a 292 with the OTT transmission.

It might be going into my '67 K/10 Suburban.
