Never read anything really negative about these cams but there was a thread where it was said these cams didn't work well with true duals and a six speed, which is what I have. BULL!!! I'm making 100tq at 1500 rpm's. I'm in 6th by 55 mph and I can go WOT and there is no lugging or pinging and it accelerates likes it's in 5th. I've lost nothing with these cams. Averging around 43 to 45 MPG, 50+ out west where the thin air is.
