Information on the 273

Bear in mind that when they were made there were lots of small engines. The SB chev was not that old and it started as a 265. Ford a 221, then 260, then 289. And lots and LOTS of 6 cyl powered cars.

AN ANNOYING STORY FROM THE OLD DAYS. Towards the end of the 70RR I owned, I decided to yank the 340 out of it (that I'd swapped in) and freshen it up, stick it in my old Landcruiser. I needed "something" in the mean time. Bought a "318" from a friend in a 65 B body, and it turned out to be a 273!!! In it went, with the Hedmans in the RR. It actually did OK, the RR had an 833, and Dana 60 / 3.54 gear

This then friend had a 50 GMC with a "built" 250 bored Chev 6, Clifford, Holley, headers, and an adapted Chrysler A833. He thought it was pretty hot.

One Saturday we all were going some damn place and got into a little impromptu thing on the highway, and it turned out the FIFTY DOLLAR 273 could kick that GMC's ***!!!! Bone stock 2BBL except for the headers and duals LOLOL
