273 is it good engine?

On a side story, sometime around ??76?? ish, I wanted to rebuild the 340 that I'd swapped into my 70 RR and put the 340 into my old Landcruiser. It had a 360 at the time. I needed something to get by. Bought a "318" out of a junker from a friend for 50 bucks, it turned out to be a 273. Dumped it into the RR but was not sure it would run very well, it might have to "come back out". Did not put on the mufflers (headers) or the hood. "We" jumped in, made about a 10 mile "test run." It was running on ?6?, then 5, then 6 1/2, then 7, then ............finally 8......blowing smoke, but ran. Came back changed the oil and plugs, installed the exhaust and hood, and ran it one summer and one winter

A then friend had a 49 GMC with a later model 250 6 into which he'd dumped a bundle. Clifford, cam, etc, and adapted a Chrysler A833. One time all of use were going to his place about 50 miles away and got into an impromptu "pull". He musta had over 2G into that damn 250 and the 50 buck bone stock 2bbl 273 KICKED HIS ***!!
