I guess "I don't run in those circles" LOL
Second owner of a V code 70 RR "back in" when "they were, had it about 7 years I guess. The orginal engine got explodated all over the I-5 one fine evening (morning) about 2AM
Driven a few sixpack and hemi Challengers and 'Cudas owned by others
Drove a friends 435 hp 427 Corvette. THAT thing was plain scary, and was not exactly factory stock.
Used to get up very very early on Sunday mornings, and take the '70 RR up N of Miramar on I-5. Nobody around. That thing would do an honest 145, 3.54 rear gear. Fairly short rear G60 X 15s, That's over 6500 RPM in high gear.
Quickest I ever went on a strip was 11.8. This was close to moving from San Diego to up N, got out of the Navy, there was a lot more in the car. It had clutch problems, and this was launching in 2nd gear and shifting a stock box essentially with a "not releasing" clutch, so there was a LOT more in the car.
