Richard Holdener to test the Piston Reversal theory

I get that guys pop ups on my browser all the time. Someone post the link if i miss it. Nicks garage should also do it, I tend to believe his stuff more than most as he has nothing to gain, just showing the data. He still dynos a lot of stock build motors only for the sake of finding out if the specs are correct in the manuals. Usually they are very close but it seems most Mopars exceed the printed values.
He did a customers 351C (added a 4bbl carb and intake only) and I was surprised how low it really was, right inline with the printed data ~ 280-300 HP? Yeah I know there were many flavors of the 351c.... 2bbls and all.. 72 lower-po 340 with a cast iron intake and early 2.02 heads... 370/383 ft-lbs. Stock cam and small tube headers.
