292 or 250 what to choose
Hey all, have a 292 inline6 in my 69 long bed. Now seeing as I live in somewhat farm country here in abbotsford, there are always old guys sitting on chevy trucks in there back yard. Well I found another 69 longbed in really great condition. Its an auto with a 250 inline6. The engine starts and running perfectly.
Question1: Whats the main difference between the 292 and 250? Question2: Should I buy the whole truck for $500 and put it back together? Question3: Should I buy just the motor and tranny and swap it into my truck? Question4: Tell me how to convince my fiance that I can buy another truck? ![]() ![]() Thanks all |

Re: 292 or 250 what to choose
The main difference isthe 292 has a longer stroke and the block is about 3/4" taller. Power steering pump brackets are specific to each.(power steering pumps for a 292 are hard to find and expensive if you do) Distributors , manifolds, valve covers will interchange but the pushrod covers are taller on the 292. The motormounts are offset on the 292 . Both engines are very tough and either would be a good choice.Here's my 292.

Re: 292 or 250 what to choose
Everyone and their mother has a V8.
![]() I would go with the 292- it's got more cubes= more torque and hp.

![]() ![]() IF you have a 292 available go that way, but their is nothing wrong with a 250. I made a comment on the inline board about how I could go places with the 454 that was in the same truck when I bought it and use half a tank of gas...............Go the same places with the 250, and the gage barely moves, even with the huge 4brl on it. Nope, I am sold on inline power here............

Re: 292 or 250 what to choose
I really liked my 250. Should have left it in the truck. Ran great. If I ever get another truck I'd like to have a 250 with a NV4500 with a 3.73 rear. That would be a great set-up.
I'd buy the whole truck ![]() Tell the wife it would have been crushed and you saved it! You're a hero!

Re: 292 or 250 what to choose
If you can get the whole truck for $500, go for it. I just had the head done on my 250(new valves and seats, as they were original and didn't like the unleaded gas) and it cost me $225. It would be nice to have a parts truck laying around because you never know what you may need to scrounge off of it.

Re: 292 or 250 what to choose
I used the alt,ps mount off a 250, made a adapter for the bottom alt mount because the 292 block is taller. You can use 292 propane pistons to bump compression, have 1.94 intake valve, and clifford intake/headers. I got a lunita cam in it that specs. out to about the same as a 325 horse/327
I reamed the flywheel bolt holes to fit the 292 bolts. |

Re: 292 or 250 what to choose
Question: A friend of mine is switching from a 250 6 cyl to a v8 350. Can he just put a different power steering pump bracket on the 6 cyl pump and use it on the v8?

Re: 292 or 250 what to choose
you can use the pump but i think you have to change mounting brackets and hoses.

Re: 292 or 250 what to choose
I was going to V8 my old 67 and got around some good running 250's and 292's and I think I'm going to keep it an inliner. I had another 67 3 on tree 250 and I really liked it. Made decent mileage with the 250.
Matter of fact last wk I bought a wrecked 66 with a newer 250, ps and a power glide!! I'm going to keep the manual tranny behind it however. It's my spring project. |

Re: 292 or 250 what to choose
Grab the 292. It is a great engine. Sure, you can get big cubes out of a V8, but the inline engines are soooo smooooth. The 292's have quite a following in some quarters - smooth power.
The 292 also has a huge amount of grunt behind it. Growing up we had a 3-ton grain truck with a 292 in it and you just couldn't stop that motor - even way overloaded on soft fields it just kept grunting along.

![]() We got guys that haul corn for us, and they say our M11 Cummins Powered tandem is "Underpowered".............They need to haul the same weight in a GM inlined powered truck, or IH 304 V-8 powered truck before they complain our truck is underpowered! I often marvel at how they are making diesel pickups now that make more hp than most OTR trucks had up until the late 70's.

Re: 292 or 250 what to choose
Hey all, ended up not buying the other 69 long bed with the 250 L6 and auto tranny. I am just trying to get my original 292 4spd going.
