I had a great local shop build a 340 stroker motor for me but I wanted stock carb and manifolds as it's going in an OE restoration. He broke the engine in using his favorite Holley carb and headers. After break-in the final numbers were 397 HP-465 TQ. After he swapped over to stock exhaust manifolds and thermoquad the final numbers were 395HP-443 TQ
