I won't dispute your points on 820 HP from a stock Hemi, but be careful about your claims of only 315 net. It is well known that Hemis respond very well to proper tuning and the reverse is true for an engine out of tune. Well tuned street Hemis were in the sub 12 range stock out of the box. Just because you have "data" that states low 13s and 315 net HP doesn't mean that was all they were capable of out of the box. My stock hemi was turning 360 HP net on a chassis dyno and I was still chasing a vacuum leak as well as total advance at the time (not to mention fowled plugs at the time). I’m sure it was close to 375-390 net by the time I got it dialed in. Stock everything! So a lot depends on the car/driver/tune/suspension/tire ect…..

Oh and PS....ad another 25 or so HP on top of those totals for the Gear Vendors OD on the car....
