273

I recently removed my 273 Commando engine out of my 1966 Barracuda. I wanted to have it checked out and rebuilt. It was getting a small amount of oil in the coolant but no coolant in the oil. Other than that it ran great. The machine shop I sent it to found a small crack in the block. I have found someone that has a 273 that I could purchase and use the block as a doner. I was wondering, seeing where I am at, should I just find a 318 or a 360 to rebuild and will one of those motors be ok to hook up the A833 4 speed transmission to?

You could use something bigger. I was thinking about this possibility with my 273. The 360 is externally balanced and I'm not sure what Flywheel you would need. Probably a larger diameter 360 flywheel and then a different bellhousing and some different linkage. That could be done but not a plug and play deal. What ever engine you will get you will need a pilot bushing in the end of the crank. There's probably other things you will have to change.
