We primed the engine’s oil system, then dropped in our distributor and Live Wires spark-plug wires from Performance Distributors. We also installed a 750-cfm “shop” carburetor for initial break-in, to check for leaks and seat the piston rings. Once the engine was warmed up, we applied a load with the dyno servo, then made one short pull to 5,500 rpm to check for problems. None were found, so we shut things down and drained the break-in oil.
