Most Under-Performing Musclecar Ever Produced?

[Bill Howell]

The Boss 429 engines were in the Torino Talledega and Cyclone Spoiler II bodies in Nascar in 1969. Ford built the Talledega and Spoiler II long nosed bodies to make them legal and the Boss 429 Mustangs to make the engines legal in Nascar. The engines and bodies each had to have a minimum of 500 units.

I could be wrong) that were the dominant body styles from Dearborn on the NASCAR tracks. If there were any Boss 429s out there I've forgotten about them.
I think Sam Auxier ran one in a class called Ultra/Stock (a forerunner to Pro Stock),in another association. I'm sure someone more NASCAR savvy than me will come on here and set us straight. Danny Durham

Danny,
In 1969 Ford and Mercury won 30 out of 54 races held. Most of those were with the Boss429 although the first few were still with the tunnel port 427.
thanks, Roland

As a modern stocker, I'll bet the NHRA acceptable rods are something much better and much lighter than OEM. That alone has to wake that engine up. Same with modern piston and rings. And probably a better crank forging. I'm just assuming that's all in the tech bulletin as I didn't bother to look.
426 Hemis never used to run in the 9's in Stock either...
