The guy I got it from, brought it to California from Colorado in the early 70s. After a rebuild, he was racing it by 1975. He did win at least one SCCA race.......I think it was a regional.
The car came to California with a non-crossflow. I don't know if that is the original engine. I hope to find out what engine came with the car. He installed the GTA as he had been racing a Giulietta all through the 60s and knew Alfa Romeo engines.
History prior to Colorado is still unknown.
That's what I know as of today.
If you have photos of your Bobsy/GTA combination, I would like to see them. I'll send you my email. brad.
Originally it should have had a Lotus 1600 twin cam. One of the Bobsy's I sold to Co. had a 1300 Lotus TC put in it. Was painted dark metallic blue with yellow trim. Last I heard it was in Tx.
I suspect the Lotus design makes more hp/cc than the Alfa design. My GTAjr dynoed at 134 hp w/Hilborn style fuel injection.
Don't know for sure - but it looks like the stacking units they use here in SF at some parking garages to maximize parking - it does allow you to stack a couple cars high, and I believe they have a plate that can be slid around to catch drippings.
Check this link - you can stack 4 high! http://www.katopark.com/k3000-1.htm
I didn't see that anyone has ever started an Alfetta Photo Thread.
So, since I backed my 76 Alfetta GT out of the garage today and thought I needed a picture of it on the snow in my driveway, we'll see if this catches on.
