Then the '72 and '73 340 was a turd, too? 'Cuz the '74 360 4BBL that replaced it was rated better than that version of the 340.
Not sure I would disagree, except that not all 360's were 2bbl.
Unfortunately, an HP 360 was short lived and it wasn't long after '74 that the 4bbl on the 360 really only meant a different induction and better durability but not much performance. But at least there was an HP 360 that got all the 340 stuff from the factory.
Wonder what cam the '75-6 E-58 360 got. Something for a different thread.
