engine is german gm 3.0 24valve twin cam injection straight 6 gearbox is a getrag manual 5 speed around .72 o.d 5th

204hp at 6000rpm 200lb torque at 3600 rpm


weight of truck is about same as donor vehicle so i guess if i do the math and gear it the same it should be pretty good. without checking i think tyres on donor are 195x65x15 axle ratio 3.7 it would top out at 140 mph + and 0-60 was pretty good
