Difference in 273

In '68, the open chamber 675 heads came into being, and were on the 2 BBL 273's. But not sure what heads were on the 4 BBL's for that year.

I don't think that they made a 273 4 bbl in 68, that's when the 340 came out...

Who would want a 273 4 bbl when you can get a 340 4 bbl??? (No offense to the 273 guys....)

67 was the last year of the 273 4 bbl and solid cam in the 273... In 68 the 273 and 318 had the same hydraulic cam...
