292

[l79m20]

Will the intake and exhaust manifold off a 250 cu inch motor work on a 292 cu inch? Am loooking at a 292 motor without and just wondering?

[1963c-10]

Yes, the manifold will fit and work, but the exhaust size is smaller on the 230/250 manifold than it is on the 292 manifold.

Thanks for the response. Will that be an issue in the future or is the openings just slightly smaller?

I always thought they had the same part number?

When I change mine on my '64 292 with a brand new one from Chevrolet, the exhaust fit just fine.

the outlet is larger on the 292 exhaust thats all

the pickups use the same manifolds, only the dump trucks had the larger exhaust. I work in a salvage yard and have checked the interchange info.... I also just pulled the manifolds of a 64 1/2 ton 292 and put it on my 65 1/2 ton230.

The 292 is a 2 1/2" dump with 3 bolts whereas the 194/215/230/250 is I believe 2 or 2 1/4" with 2 bolts

The 1/2 to 1 tons had a 2 in outlet. The early ones had 2 bolts & the later (about 68) had 3 bolt flange. Either will work if you get the corresponding flange. The 1 1/2 & larger trucks used a 2 1/2 in. opening & points straight down. You will need somefabrication to use it.

And you have the option of hot rodding it with the Offy intake + Headers or Langdon Cast Iron headers like so many of us do. Some $$ but then you can run a modern 4bbl.

If you found a good 292, grab it. It's a good investment even if you don't use it. They are getting harder to find and are very popular still.
