Others may have better information, but my memory is that the original SCCA classes were displacement based and almost pure stock while the later "Cal Club Rules" were more performance based; with faster cars with smaller engines competing with slower cars with larger displacement engines (and other allowances like fender flares, etc.). Cal Club was the California Sports Car Club, a rival to the SCCA until it became the Cal Club Region of the SCCA, and their rules philosophy was adopted for SCCA racing. So, after all that, I kinda remember that the change occurred in the 60's so the Alfas may have been in different classes before and after the rules change.

I am looking for some information about SCCA racing in the 1960's.
There were 3 classes I am asking about...G Production, F production and E production.
Most specifically engine sizes for each class.
Once this is determined I might have some more questions.

I had a G-Prod Alfa in the 70’s, and worked for a fellow that raced in D and E prod. In this era, G-Prod was 1300 with 2-bbl Solex, F-Prod was 1300 with 2 Weber’s and I think 1600 (101) with Solex, E-Prod was 1600-1750, and D-Prod 2000.

 

Thank you for the information. I was thinking that G production was in 1300. I wasn't sure if F was 1600. The Alfa's sometimes ran with the big boys and outran the "lead sleds". I believe Dick Blizzards spider veloce ran in F production.

 

I think Don is spot on (although I’m not sure how things evolved over the later years). I raced a Giulietta with a 1600 & Webers in E prod “1600 Veloce”. At the same time my brother raced a Duetto with a 1750 also in E prod. In hindsight I should have put a 1300 in my car and raced in G or F prod. Although I could compete at the regional level I could not keep up with the MGB & Porsche 356 national cars.

looking back I am most intrigued with the later G prod cars (1300 with Solex). As the years went by I believe they were the last competitive Alfa in the production classes. They acquired all of the learned advancements of the other 750/101 cars and as the rules opened up in the 80’s furthered the racing technology of these series of cars.

I agree to the extent that the level of performance was directly related to the creativity of the Solex preparation. I ran in F Production but was aware of the Solex preparation in G. There are rules in the GCR. HA!!

Joe Loccario`s 1750 ran in D production in `70 & -`71. After the 2 liter cars came about they were put in DP and the 1750s back to EP with a weight increase.

 

I’ve always wondered where my car ended up.

In 1979 I traded my restored 65 Sprint GT for a G-Prod 1300. Went to two schools, discovered aviation, and decided between attractive young ladies, airplanes, and racing an Alfa, that I could afford two.

I sold the race car, with fresh engine, tires, and brakes, to a guy from Florida. I think his name was Fred.

Anyway, I heard later that he felt some chest pains, drove himself to the hospital parking lot, and that’s where they found him somewhat later. No more news on what happened to the car.

 

Just found these....

• DP Production: Giulietta Veloce
• GP Production: Giulietta

These classifications changed a bit later through the years

1962 SCCA Classifications

 

Remember that in 1962 VERY few modifications were allowed in SCCA production car racing. Giulietta Veloce's were good enough from the showroom to compete against cars with greater displacement. As the rules were liberalized, many cars that were far inferior in the showroom became very competitive against our beloved Alfas!

 

Noticed the rulebook for 1962 was very specific and had the technical specifications for each of cars that participated. See the pdf attachment.

The rules allowed for matching and polishing of the head.

Any insights on that?

 

The SCCA Production Class rules have always specified what modifications you can make, not what you can't. So if the rules didn't specifically say you can, you can't. In 1962, the rules gave you the freedom to match the intake manifold to the head, but not enlarge the port. Over the years, this changed to allowing material to be removed from the port, but not added.

 

I had a Yenko Stinger (Corvair) in the 70's and it ran in D Production. As I recall, cars were placed in classes based upon overall performance, not specific specifications. So my Yenko had displacement and HP advantages over others in our class (Datsun 2000 roadster, Jensen Healy, etc.). Mods were limited (we had to run drum brakes vs. discs). At that time 1600 alfas ran in E production as spiders or in B sedan (as GTV's). If your car was not listed in any class, you could not run it.
