Barry R Thanks for the info But a 1" spacer under that throttle body and get 5-10 hp at 5600 rpm, been there done that. I will look into the 1350 cfm and do it for starter on the 489 motor. A throttle body and a carb have different flow performances. Dones the
oil rings clear the piston pin hole or are they in the pin hole? I like the NOS plate.
