Stephen/Horace,

Yes, that would have been a COPO. I'm not sure how the combos fit in the class guides back in the old days, so I can't say for sure what combo Olges may have actually ran. But I feel rather sure it would have to have been the ZL-1. I don't think the 427/425 can make it to B. The last time I checked-about a year ago-the 427/425 '69 Camaro is a natural D car. The ZL-1 is a natural B, I think it breaks at 6.56.

Also, I do recall reading in the engine specs at NHRA's site that the ZL-1 as used in SS can be either iron or aluminum block.
