The power train of the GTA/GTV came straight from the Giulia series of sports cars and sedans of the early 1960's: 1.6 liter DOHC engine, 5-speed gearbox, solid rear axle. Both versions had aluminum body panels and plastic windows. The principal difference was that the GTV's engine was taken out to 1.75 liters.
In the early days of Trans-Am, the Porsche 911 was competitive with the Alfa GTA (and also "owned" C-Production). But Porsche was concentrating on prototype racing in Europe, so lightweight versions of the 911 were not available to SCCA racers in the States. It fell behind in development and out of contention, especially as preparation rules for the Trans-Am pro series were liberalized.
By 1971, Kwech was the only Trans-Am Under Two Liter competitor who could consistently run with the factory-supported B.R.E. Datsuns. (The other principal competitor in the U2L class was the BMW 2002.) And run with them he did. He gave the B.R.E Datsuns fits all season long; the championship went down to the last race of the season at Laguna Seca where it was decided in favor of Datsun. For those who cared about U2L, the competition between between Alfa and Datsun was just as captivating as the "Mustang-Camaro Wars" in the big-bore class.

|Kwech's "all pro" (sponsored) Alfa for 1971 was a GTV, not a GTA, although they were essentially the same car. By|
now it had left-hand drive, a fully caged roll bar, and stiffer suspension. This is the restored car at a vintage event.
