I bought a great little '67 econoline truck here a couple years ago out of the classifieds. It's been a blast, but the motor is a knocking, and the diagnosis is that it needs a new motor. Don't say V8... I don't have the time or money for the dream upgrade... maybe when I'm old and angry It came with the stock 240, and I'm looking to make this super simple and do a rebuilt long block. I've read a bunch of tech info on the 300 being an almost perfect match as well, except for maybe needing to replace the thermostat housing? I'd love to get the extra HP's, but I don't want to through any curve balls to the guy I'm doing it with, so I might just go for the 240 so it goes fast and easy. I'm on an island off Cape Cod, so there is extra shipping... Can anyone suggest a engine supplier in the New England area that you could recommend?!? Thanks for any ideas or suggestions.
I also have a 67 econo p/u, had the 240 in it. I bought a short block 300 from a local salvage yard, rebuilt it. Had the 240 head rebuilt and put it on the 300. Made good power.
Ed, I have had several 240 s and 300 s . Both are very decent an reliable engines . You say you have a rod knock. Sounds like it was caused via BAD CAM Bearings not delivering oil . I would simply send it out to a N A P A machine shop. These engines are way tougher than most folks think . scrubba
I'm afraid besides the rod knock, there is also very low compression in one of the cylinders. Besides just wanting to have the piece of mind of a new engine, the cost of getting the truck worked on out here is super pricey... $75 to $100 an hour pricey. So it's pretty easy to justify the replacement over the rebuild since i can't do the work.
There's a Yahoo group called OldEconolines that is really good with these kinds of questions. Since you have a '65-67 with a 240, you're in great shape for a swap. A 300 will pretty much drop right in and bolt up to your trans. You could also do a 289/302, but that might require minor work on the mounts and doghouse. A 300 would be a great choice.
