Your Montero will be the narrow pattern block.

Really?

Best bet is to measure them both before you pull them. Yes its a pia but so is trying to bolt a 12.25 engine to a 13.25 trans or vice versa. I learned about narrow blocks the hard way LOL.

Now I'm more confused than I was before. The only saving grace is that you say that your information may not be complete. I can't place my vehicles in any grouping with any certainty.

Here is what I have, based on my knowledge and vehicle pink slips.

Vehicle 1: 1985 Montero (Sorry, I thought it was an '86, but the pink slip says '85)--Vin JA4FJ43E5FJxxxxxx, auto transmission.

Vehicle 2: 1980 Dodge Colt Wagon-- RWD, 2.6 engine (G54B), standard transmission.

And then there is Vehicle 3 (just to add to the confusion): 1984 Montero, VIN JA4FJ53E3EYxxxxxx, standard transmission.

The chart doesn't list an '85 Montero (vehicle 1) with auto transmission, but it may fall into the first group, with narrow block.

The chart doesn't list an '80 Colt, though I'd tend to put it with the '81 Colt with standard transmission, with wide block.

Vehicle 3, the '84 Montero with standard transmission, seems to fall into two groups, one with narrow block and the other with wide block. Thats a definite maybe.

The chart, btw, is very good, very informative. I've made a copy.

So, we're back to your cautionary statement. The only way to tell, really, is to get under each vehicle and measure.I can do that with the '80 Colt and the '85 Montero. They're here with me. The '84 Montero is in Maine, probably buried in a snowbank.

Please, keep the information coming. All this is stuff I need to know.

I finally broke down and measured the blocks. I think the measurements agree with what you all have been telling me. I measured the two lowest bellhousing bolts on each. I assume that is correct.

The '80 Colt is 13.25, and the '85 Montero is 12.25. That leaves me right where I started. I don't have a spare engine handy I can drop into the Montero. I'll have to drop the pan and see what damage was done, whether its repairable.

In the event I have to hunt for another engine, will any 12.25 engine work? Or does it have to be/have been mated to an auto transmission?

Not sure what this guy has here. The ad has a phone # you can call.

The guy in Texas has his price set too high, particularly for the usage I plan for that Montero. I can get one for $500, I think, at a wrecking yard in this area, or $800-$850 for a Japanese take-out shipped over here. I haven't done either yet because I don't need the vehicle running right away, and money is too tight.

I was really hoping that I had an engine in the Colt which would work.

Thanks for all the help and information you all have been willing to share.

You can swap at least an 85 and later manual block to either the KM145 5spd or the KM148 a/t from the 87 and later models.

If the donor a/t was a 3spd a/t truck, I think it has the funky old bellhousing, but I've never tried to swap that block. That tranny was a Mopar torqueflite, I think. Last used in 86 in the monty, dunno the pickup.

Try this guy for a long block takeout. Phil at 770-474-4417.

any narrow pattern block will work. Don't forget to check Caravans of the same vintage 84 -86.

Hold on a minute. Are you saying that I could take the engine out of a Caravan (yes, I think they did have a 2.6 at one time. Was it the same Mitsu engine?) Are you saying that I could take a transversely mounted engine, turn it 90?, and mount it into a rear wheel drive vehicle?

That would be terrific. There are many more of the Caravans with auto trans than there ever were Monteros. More of them failed because of the transmission than because of the engine. If that is in fact possible, my chances have increased immeasurably.

Can anyone say with fair certainty that a Caravan 2.6 could mount in a Montero? What about one of the v-6 engines from a Caravan?
