article from 2017... How Bad Did Mopar’s 340 beat Ford & Chevy?

And................

Roger Huntington's American Super cars book. His testing & magazine tests. He would estimate the actual [ net ] HP from 1/4 times, gearing, weight etc.

340 six pack, 3.55 gears, 14.5 @ 99. Adv hp, net 310.
350 Z/28, 4.10 gears, 14.5 @ 99. Adv hp 360, net 320.

Another lot of his tests...
'68 340 Cuda, 3.23, 14.9 @ 95. 275, 290 hp
'70 340 Cud, 3.54, 15.0 @ 95. 275, 290 hp.
'67 350 Camaro, 3.55, 15.8 @ 91, 295, 230 hp.

Pretty obvious who is telling porkies...& it is not Chrysler.
