I don't get it. The 340 had pretty much everything that that Olds motor had, plus special swoopy exhaust manifolds which the Olds didn't. I would like to see what a bone stock '71 340 (with the T-quad and a '68 manual-trans cam) would run against this Olds. Can't see how anyone wouldn't consider the early 340's a top-to-bottom comprehensive factory performance motor.
Or.....were you just trying to stir the pot? :D
