Who’s the Boss? 1970 Ex-Tasca Ford Mustang Boss 429

First, it’s a race car, not built for the street, so they didn’t take a streetable Boss 429 and hack it up. Second, no, the Boss 429 was more understated than its smaller sibling, the Boss 302, and therefore was not supposed to have those Boss 302 stripes. With that out of the way, Boss is just one of the words used to describe this beautiful “race car.” It is available for bidding here on Bring A Trailer. There are 6 days left in bidding, and the current bid, as of this writing, is $150,500. The vehicle is currently located in Mount Airy, Maryland. Thanks go out to Curvette for this amazing Blue Oval tip!

This Boss 429 was delivered brand new to the famous Tasca Ford in East Providence, Rhode Island. It was campaigned by Carl Tasca, who apparently obtained a NASCAR-specification 429-cubic-inch Boss V8 that Richard Petty used in the 1969 season. I am sure there is a lot of discussion somewhere about why Petty moved from Plymouth to Ford and then back only a year later, but there is even more discussion online about whether this is a Petty motor or a Holman-Moody-prepped one built for Petty. I am also sure there will be plenty of comments about it here. The engine has a Wieand Tunnel Ram intake, dual Holley four-barrels, and custom four-into-one headers, all installed at Tasca Ford.

Georges Speed Shop in Dayton, Ohio, one of the premier speed shops in the country, has been operating for over 70 years and performed the engine rebuild. The brakes are front discs with rear drums. The Boss 429 has an upgraded suspension with heavy-duty front hubs and oversized spindles. Everything about this car is clean, including the immaculate Wimbledon White seats and door panels. There is minor damage visible on parts of the body, and with the number of pictures available in the ad, you can see every part of this car, inside and out.

In May of this year, a 1970 Boss 429 sold on Bring A Trailer for $410,000. Mecum Auctions shows a 1970 and a 1969 that sold for $275,000 and $349,250, respectively in 2023. There is a Deluxe Marti report, a necessity for any high-dollar Mustang being sold or auctioned, listing factory equipment, colors, and production statistics, along with a build date of September 16, 1969. This is a beautiful car with a great race pedigree and documentation to the moon. Let’s see if the bidding goes that high, too!
