273 / 318 Exhaust Manifold Question
Just studying you car build on what came stock on the '67 273 4 bbl Commando, in your '67 Barracuda S.
Thinking that should have been a factory 10:1 compression ratio engine with 273 closed chamber heads.
Unless of course you changed the pistons at the time of your rebuild?
Also wondering if you installed the new cam straight up, or did the 4° advanced thing?
'67s came with a larger Single exhaust, muffler and resonator. 50 year old system. Thinking you could improve greatly with a full dual exhaust?
