is there much of a diffrence inbetween a 292 and a 235? as far as external parts example valve cover, manifolds, side pan cover.
got what a old man told me was a 292, i am thinking 235. thats what it looks like. gonna tare into it this weekend
About all they have in common are six cylinders in a row, overhead valves, and distributor on the right, intake/exhaust on the left. If you write down the casting number off the block you can find out what it is pretty fast just by googling it or hitting one of the inliners sites.
A quick visual check--does it have one long side cover or two short covers? One means a 235, and two mean a 194/230/250/292.
The little bit I've learned recently about Chevy 6's is a 292 is taller than the others and has different motor mounts. I had a line on a good 292 for my 64 Nova but a local 6 cyl guru told me I wouldn't be able to close the hood with it installed along with having to make up new motor mounts.
cgaswillys- the 292 is only 1.75" taller. you could get the low profile breather like some of the 292's had on trucks and i bet it would work. and only one new motor mount! hahaha
292 engine will bolt to any modern day transmission, so you could go with a TH350, 700R4, 2004R, or the incredible edible POWERSLIDE. Sticks are easy. Hoggyrubber has a good idea of how to install in Nova. But can't understand only one new motor mount thing, would think it needed both or none if going into 6 cylinder equipped nova.
Because one mount is offset on the 292 block. The other side is the same. Someone posted a link on Chevytalk to some Langdons mounts that let you put one in a 49-52 Chevy car and you could see where the one was 3 or 4 inches back of the other, the kit compensated for the difference.
The "old man" may have meant it is a 261, he may know it's more than 235 and he got the numbers wrong.
Keith - Both "HEATHON" and "roddiniron" are on the right track about the sidecovers. Thier error though, is that while the 250's etc. do indeed have two sidecovers, the 292 covers are different, in that they're 2 inches deeper (6" total). The 250 and smaller motors in that series have covers only 4 inches deep. That's the whole skinny on ID'ing the 292s. P.S. At least half of the "292"s I see in cl***ified ads or at swap meets are 250s. I'm gonna bet you've got a 250 on your hands. (-:
the p*** side mount on a 292 is the 3-4" foward of the drivers side. the bosses in the block switch places with the fuel pump. you can run a 250 cam in a 292 if you use a elec fuel pump. i was thinking the same thing as r pope- i bet it's either a 261 or 235. if it's a 261 - cool find!
that is good to know if you are thinking 292 out of a custom 10. thanks for clarification of the p***enger side mount. Chevy works very hard not to make things too easy for us HAMBERS.
The motor mounts that are sold by Langdon due indeed have one mount offset, but that mount is actually for the drivers side, not the p***enger side. The offset is to clear the steering on a 49-54 car, but it will work in anything that way also. Don't believe me? take a closer look at the picture. See that boss welded to the backside of the mount? try getting that to work on the p*** side... As stated, The easy way to tell a 292 from the 194/230/250 is that the motor mounts are staggered. The 235/261 has the distributor in the middle of the block, the later 194/230/250/292 has the dist. at the front. That's the quick way to tell. after that, there are many little things that can separate them as well. For newbies, it's best to look up the casting numbers...
sorry, i was actually talking about the factory mounts not mr langdon's mounts. i'm sure his setup is totally different. the 292 motor mount bosses are totally different on the p*** side than drivers or either side of 250/230/198. they are not in a single plane so they require the spacers for the lower two bolts in the 60's chevy trucks. i'm not complainin about gm but i don't understend that design.
the pics that i have are to big to post up. Looks like a 235 to me, has a internal water pump like the later 235. the motor mounts oare the same on either side. They are forword mounts but not under the timing cover. it also has a name plate rivited to the side just forword of the fuel pump that says "SUN MOTOR SUPPLY" and some numbers stamped into it but can't tell what half of them are.
...what about the lifter covers? One long one, or two shorter, but taller ones? I suppose, once you get it apart you could mike the bores, too. 235 = 3.5625" 261 = 3.75" 230-292 = 3.875" (194 is same bore as 235) ------------------------------------------------------------- Guitar Guy, How does that engine run without a cylinder head? 6narow
Yeah, that's a Stovebolt. Its either a 235 or a 261. Forgot to mention that those engines had a different valve cover than the later "nova" engines. Also, the one-piece side cover, whose bolts attach at the seal. The nova sixes used a "peaked" cover with that attached with a center bolt. The only way I know to tell between a 235 and a 261 is to either run the block numbers or pull the head and measure the bore. The 261 used a 3 3/4" bore. 235 used a 3 9/16" bore. Manifolds are different, too.....man, I forgot to mention a lot of stuff! ... 6narow
As for telling if it is a 261, the first thing you do is look for what they call "captains bars" located on the block just above the starter. Then you verify by checking the casting number which is also located on the p*** side of the block below and forward of the distributor. Some 53-54 235's had the bars, but then those also had the earlier style water pump. If it has the '55 up style pump and the bars, it's a 261. Can't tell in the pictures, but if it has a triangular 3 bolt pattern on both sides of the block (for mounts) then it's a 58-62 engine. No 3 bolt mount, then it's a 55-57. It has a 54-59 style truck bellhousing (because of the pedal start setup and angled corner mounts). No bars, then it's a 235... Any chance you could post a close up picture of the front drivers side motor mount area? Thanks!

No. Mounts, not starter... It would require a different picture, as none of the ones shown have a clear shot of what I'm looking for. I am trying to design some brackets and I need to make sure the design clears the 55-57 type mounts...
Yes, but that doesn't mean the engine is. Most 58-62 engines still had provision for the front corner mounts.
Snarl, I was trying to get you a better shot of the area above the starter, so you could tell us if you see the "captain's bars" you mentioned. ...so do you? I see some raised ribs, don't know if that's what you were referring to, though. 6narow
