What did the HP peak at? I am guessing that with 360 TQ, you must be revving that thing to the moon.

Graph would be great.

Over 500 crank from an HR 355? That's DAMN impressive!!!

Many M6s don't put down that kind of power, those numbers are nuts for a cam that size through a big stalled auto.

What brand stall? The ones performabuilt ship with their trannys?

Llyod seems to already have a great idea what the heads like. Can't wait to see some ported combos.

turn your flash off and take a picture of the graph, I want to see that bad boy. Great results!!! At what rpm did you make your peak torque? It was a relief to see that these heads are in fact performers. I am installing mine today and I am beginning to thing that 450+ whp with these heads through an m6 is attainable...good news
