'A-Body Showdown' ~ 273 'Commando' vs. 318 2-Barrel
No Mods .......... Stock vs. Stock
273/235 HP 'Commando' ~ 4-Speed with 3.55 Gears
vs.
318/230 HP - 2-Barrel ~ 3-Speed with 3.55 Gears
Remember, the 273 'Commando' came thru with 'laughable' {9.25"}
'Auburn' Clutch Set-up.
The 318 2-Barrel came thru with a bigger unit {10.50"} 'Borg & Beck' style.
That would make a difference,
