Hey, mega flashback! :o

Should get the engine onto a dyno for run-in or take the old girl to a dyno dynamics dyno.... Now with the twins and the crane cam you have, i would estimate about 250HP at the fly wheel/flex plate.

Again, this is just going off the specs you have posted... I'm sure there are folks on here who have had similar setups (in their days!!!) who would happily quote some more accurate power figures!
