And when I see a '69 Mach 1 cross the auction blocks with (big bold advertising!) a 390 under the hood for big bucks, I want to yell...sucker!

And I would gladly race a stock '68-'69 340 Dart with a 4-speed and 3.91's against a stock '66 Chevy II 327/350 with 3.73's. I think it would all depend on who was driving.

Jeff, as a general statement, I agree with you. However, I was fortunate enough to have a very fast '67 390, 4-speed. Bone stock, just as it was delivered, it ran 13.8s@103 mph. The other 390 Mustangs were running very high 14s@95 mph! The only cars that I couldn't beat were 396/375 Camaros and Chevelles. To this day I have no idea why it was so much faster than the average 390, but I sure surprised a lot of people with it and I had a lot of fun.
