Anybody see horsepower TV? They used the new Ford Boss 351 stroked to 427 and got 610hp!!!!! Cam was a trickflow 232 / 248 duration 585?/590 lift, trickflow heads. They only used 330 open and 130 seat valve springs and did not float valves all the way to 6500 rpm. I have the identicle cam and floated the valves at 5500 rpm with 145 / 370 until I went with 170 seat and 450 open. Anyway they used the generic
oil pump where the shaft did not protrude thru the bottom cover I thought was risky. Anyway 610hp!!!!!!!!!
