Is there an easy way to tell if an I6 is a 250 or not with out looking at the engine number? Planning a trip to the pick & pull.
Thanks,
Guy

I think the engine mounts are straight across on a 250 and offset on a 292. there are other diff's ,but the mounts are the easiest way.

The lifter covers on the 292 are 6 inches tall I believe. And 4 inches tall on the 250.

I have a 250 6cyl in my truck now and the plates are 4" and the mounts are straight across. both those guys are right on the money.

Telling the difference between the 292 and the rest is pretty easy as the others have mentioned, but telling the difference between a 250 and say a 235 is a bit thougher. Even if you run the numbers on mortec.com, mine showed that it was either a 250 or 235. Seems the best way to really tell is to open it up and look at the pistons. If they are dished then it is a 250. Sounds suspicious I know, but that's the best I could come up with. All was confirmed once I measured the bore though.

Sorry this wasn't more help.

This might be overly simple but on my 67 glove box sticker the options is listed as
L25 292 CU IN I-6 ENG
