I run a version of the 60212 that UDHarold had ground on 112 LSA in my 408 BBC. It has 049 heads with 2.19/1.88 valves and 10.25 CR. It has headers/Edlbrock AirGap with a ProSystems 950hp on top. Running 19 initial and 37 all in at 2200. It is a 4sp with 3.73 gears. It is very streetable and runs real good for a baby rat.
