Thanks to this site I was able to(after all these years of not knowing where to look)find the vin.# on the block,and it's the original block for my COPO.By the way I have a fresh 427 in the car.12.5 comp.open chamber steel head.3/8rod,roller cam,tunnelram.has run
[email protected] in 1/8 mile on street tires w/mufflers spinning all the way thru 1st gear.The car looks and sounds like an old superstocker.Also brought the car to the Eastern Camaro Nats. in Mooresville N.C.and took second place in the custom trailered class and scored 920 points out of 1000 good enough for a silver certificate..
