Yeah I'm "That Guy"
1964-1965 273 were theonl
yones that had a (small) diffrent crank register. The rest were the sameas 318.Since nobody has touched on what I consider the major difference between a 273 and a 318, I guess I will! The register on the rear of the crank of the 273 is a major limiting factor when it comes to finding compatible equipment, and thus will be overlooked by the knowing Mopar public! Unfortunately, not everybody knows of this and will just throw in a 318 in place of a 273 and go racing!! That is until the front pump wallers out after just a couple miles and renders the trans useless!! Now, try coupling that 273 with a 68 and later trans!!!....not gonna happen!!
