I had Muffley's Auto Service in Girard, OH install the BP38313CTC1D into my 1978 Camaro Type LT. It was dyno tested at almost 440 HP and 475 ft/lbs of torque. It started right up on the first turn of the key. Very strong motor with a great muscle car sound. A very nice engine for cruising around town in but when you stomp on the gas the power is there and it becomes a beast! I couldn't be happier with my BP 383 stroker!
