Now I didn't mention anything about the drivetrain on this car. I just stated motor mods. The car does have an Art-Carr built transmission with a FRPP 2200-2800 Stall and 3.73 gears with posi spool. Rear upper and lower control arms. The dyno run was done with the converter locked. Could the converter being locked have caused the high numbers? There is several other mods to the car but no HCI Combo. Opened valve covers to install 1.7 roller rockers and a 1/2 intake spacer for heat.
