My MRL 408 is finally running.

01heavey that is a real nice looking dart. Engine sounds very similar to mine but with a much bigger cam. I'm very happy with mine really the only reason I want more is because my dads 410 made 635hp and 550tq. However he can't run pump gas.

Was the engine builder aware of your goals? Either way, at 3200 lbs, a true 550 oughtta be plenty to run deep into the 10s. Keep us posted!
