The guy refused to ever give the Corvette a second chance.
What awesome cars Pontiac built for us and gear head management cleverly got into production. Kind of the same way they started the first muscle car ERA with the 64 GTO they ended it with the Super Duty Firebird.

11 years of legendary Pontiac performance excellence that forever changed the performance car industry.
Back when the ‘73 SD T/A made its debut I read an article in Hot Rod magazine where they did a few tuning modifications to a new one and got it to run 13.50s. It had 3.42 gears and I’m almost positive a TH400 automatic.
They put some better rear tires on it for traction, welded some flanges into the exhaust to be able to uncork it, did minor distributor mods to bring the advance in quicker and played with secondary metering rods from what I recall from reading that article with great interest.
I found the article particularly intriguing as a young teenager because I was already a car nut by then and was lamenting the death of the performance car, the SD Firebird was pretty much the last gasp at that time.
Does anyone have any off the showroom floor actual performance data, in other words time slips from one of these cars from back in the day?
