About “Twin Cam #1”

1976 CHEVROLET COSWORTH VEGA
Mahogany Metallic - Buckskin interior

1 of 1,447 Cosworth Vegas of 160,523 1976 Vega production.

122 CID (2.0 L) DOHC Aluminum Inline-4 - 16 Valves - Forged Steel Crankshaft, Forged Aluminum Pistons, Stainless Steel Headers, Electronic Fuel Injection.
4-Speed Manual Transmission

I owned this Cosworth Vega from 1982 until the mid 90's. That's me behind the wheel in 1988 for this car show photo.
The car had 25k miles. Car was refinished in the mid-80s with the original color, acrylic lacquer paint and clear-coated, and new stock stripping. I bought an nos set of stock alloy wheels and nos Goodyear radials. It did well in car shows gathering many 1st place awards. It was entered in the Super Chevy Sunday show in Pa. in 1987 and 1988. It won best in class (open class) both years. The car was featured in Super Chevy magazine in the June 1988 issue. I wrote the article, captions and supplied the photo slides.
I finally replaced this missed Vega - an original 1976 Cosworth Vega, same color with the optional 5-speed transmission - only 1,592 miles (see garage).

About “"Bud"”

In late 2005, I decided that I didn't want to subject my '66 Corvair daily driver to another winter of Pennsylvania road salt. Its floors had virtually no rust, just a little surface rust, and I wanted to keep it that way! GM was having one of its rebate promos, so I checked into how much a Cobalt would cost. The local dealers (I have three within 10 minutes!) all came in too high, but there was one about ten miles away that quoted me a price that was just too good to pass up. They pitched me the SS, with the equipment I wanted, cheaper than one of the other dealers quoted me on am LT!
I call it "Bud" because I'm a big NASCAR fan, especially the Earnhardts. Dale Earnhardt was, is, and always will be THE MAN! Dale, Jr. is currently my driver, because, after all, he is his father's son. Now, at the time, JR. drove a red Chevy SS with "Bud" painted across the hood. What else am I going to call MY red Chevy SS? (I have no plans to repaint it in his current colors!)
And for all you other NASCAR fans out there, I'm open to guesses as to what Bud's license plate "BOOG8Y 3" means.

None (Yet...) except a set of Falken tires - it used to corner well, now it handles like a go-kart!
