1967 Chevrolet Corvette Stingray 427 Engine

The NOM 427 is a 1969, with high performance stampings on the heads & block. It was said to be a L72. When I changed the oil pan, you could see the part numbers on the pistons which do show as a L72's. L88 snowflake intake. 4 bolt main. The M21 transmission has the matching vin & has the tag 3880853 which indicates a L36 or L71 use. I believe the car to be the L36, a 390 hp car. All tale tell signs are on the car indicating a big block car. 3.55 Positract. Rear sway bar, rear axle caps, left side hood release (right side has not been drilled or filled in), fuel line size, even the correct throttle bracket. Transmission shifts the best of any I have driven...like the bolt action on a rifle. No grinding or jumping out of gear. Clutch & brakes are good. Engine pulls nice & does not run hot. Car goes & stops straight.
