Just how quick were the 273 Commando's in the Quarter-Mile.

AJ/FormS to be a little nitpicky, I don't see .96 hp per cubic inch race engine territory, maybe they way they did in the 60's. Now days 1.5:1 and above is in the race only territory. 1:1 is more like slightly hot street engine, decent cam 4bbl and headers gets you there.

And the 45 more cubes of a 318 doesn't make hp
If you build a 318 to commando spec it would put out similar hp just at lower rpm with more torque.
