273, the good points

To actuly make useable power @7000 rpm it will require a cam that WILL get noticed! In our little 273's! & yes the 8 3/4 was first optional in 1965. I like the ford valves. idea,just a tutch biger without over doen it! Its real easy to "over do it" on the 273 man. My combo pulls hard from 2500-5300 rpm after that its just noise & power drops off fast. & That's a pretty a conservative cam that's in there too. i say build er man thease motors are underestimated if done correctly again do yer home work there easy to "over" do & make really week in the lower rpm range.
