This is my Cam specs (1.5 ratio Crane gold rollers). My engine is a 418 (340 based .040 over) 10.5 :1 compression that dynoed at 490 horsepower and 516 torque. My car has manual steering and brakes so there is no extra load on the engine. My converter is a 3500 stall TCI and I am running 355 gears. It is a handful on the street especially if you are not running drag radials, BFGs are NIT gonna cut it. I just got 255/60/15 MT SS tires (the biggest you can put in a stock wheel well with the llips rolled). The idle is rough (but I like it) and like others have said it idles at about 750 RPMs.
