I drive a VR 355" with 9.3comp and a short cam like yours (4502 Crow). It is such a prick fighting the brakes. It used to idle along at 13kph before you even touch the throttle (even when towing). Bigger headers and intake mani helped drop idle torque. But stally is what I really need at some stage. P.S going from 3.08 gears to 3.45 gears changed cruise rpm on the highway from 1900 to 2100. Basically nothing really and you soon get used to it.
