Im using a 1971 400 block crank & heads
heads fully reconditioned new guides and seats on the exhaust 2.02 intake 1.65 exhaust
Keith Black pistons 9.3-1 compression ratio with quench
Comp Cam with matching springs mid range for torque 1500-5500 rpm
rotating assembly sent over to Crankshaft Craftsman full balance
I bought he pistons from Tmeyer engine on Minnesota who is a cleveland engine expert
with this cam the engine should make 325 HP and 425 pounds of torque which should make my old land yacht move down the road nicely
