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?

Where is the crack? Oil gallery pressure is higher than coolant while running but when you shut the engine off the oil pressure goes to nothing while the coolant has to cool off to drop pressure.
Antifreeze will leak through where water will not.
That crack must be fairly small.
Another question is, is the engine numbers match to the chassis? If it is the engine that came in the car, I would seriously try to get it repaired. Numbers match are becoming scarser and more valuable.
