Early 70's SCCA Class Designations

[CurtEgerer]

I'm looking for general information on what the various SCCA racing classes in the 60/70s required (i.e. C/P, D/P, E/P etc.) in regard to 911's? Not today's designations, but those back in the day.

For instance, what class would a completely stock '72 S have been placed in? What about a stock T? What about something with a modified engine and wider wheels/tires? Thanks.

When I raced in SCCA during 1977-80, my 1967S, which Grady Clay set up for SCCA at that time, raced in D/P. I think that now it is in C/P.

Hi Curt,

I don't have the specs at hand, they should be Don's shop, but let me try to dust off some of the cobwebs.

This dates from around 75-76 on, I will defer to someone older for prior info.

EP was generally 356 and 914 and some 912.
There were a few GP 356s.
DP was both SWB and LWB 911 up to 2ltr then in early 80 924.
CP 914-6 Some 911s but I think this was prior to mid 70's.
BP was where a Trans Am 911 would run.

Now for some fun.
1 Bob Overby followed by John O'Steen
2 Don Istook DP SWB sold to Dave Bouzaglou
3 Don Istook DP Targa
4 Grady in the shade
5 John Schneider DP 924

I think any 2.2 or 2.4 would have been in CP. I do not remember seeing any which maybe because a 914-6 would be more competitive. The rules speced what you could do to the motor and the car. In the above photo #2 the SWB had been switched to LWB and was fitted with wings to meet the track spec that car started as a 67 tub.

Damnit Curt...... ya'got me looking through my house and garage at 6:00am for my '70's SCCA GCR.... and I can't find it.... ...

Think I loaned to my buddy...

Will get back to this.........

[CurtEgerer]

I heard you didn't have enough to do anyway Chuck ... I knew somebody would have the rule book!

So out of curiosity, what class would a car like mine have been classified in? 71T, 2.5L engine, 7 inch wheels, everything else pretty much stock - B/P???

Try here...

...and look under:

SCCA GCR (General Competition Rules)
1962 GCR
1967 GCR
1969 GCR

SCCA PCS (Production Car Specifications)
1962 PCS
1967 PCS
1969 PCS

In DP we could run 7&8x15 but limit 2.0.
The 2.5 would most likely be CP but not competitive against a 914-6 like Grady's or the Datsun's.
BP would be amost the same as Trans Am spec if not identical which would be 2.8 or 3.0 RSR's.

Thanks Rich! I don't see any of the Production classes allowing a displacement increase (beyond 1.2mm overbore).

According to those documents for 1969:

A/P -- 904
B/P -- LWB 911E/S Coupe/Targa
C/P -- SWB 911/911L/911S Coupes & LWB 911T Coupe/Targa

Still can't find my early 70's GCR... but Rich's link has some very cool information

This is the way I remember it... remembering that I was an Alfa guy back then...

When 911's first hit CA. in '65-'66 they were D-Production (Jerry Titus's first drive for Vasek was a D-Prod 911)

When the 911S hit in '67 it was put into C-Prod, then soon after all 911's fell into the same category... Davey Jordan, Milt Minter, Allan Johnson, Bert Everit... and the rest, were all C-Prod winners and champs in '67 and '68...

However, in both '67 and '68 'they' pulled a fast one on John Timanus and also got the 911 in B-Sedan....
The same weekend in Daytona when Allan Johnson won the '68 C-Production run-offs, my friend Vic Provenzano was fighting off a 911 in his Afla GTA for the B-Sedan title...

After the '68 season Timanus got wise and threw 911's out of Sedan racing...

In '69 through about '71 I remember the 914-6's racing the 240-Z's for C-Prod... but was not sure where the 911's raced... and with Rich's link, looks like they were in B-Prod with the small block Corvettes and Cobras

Into the early '70's EVERYTHING started changing in SCCA... John Bishop started a 'Pro' series IMSA that EVERYONE wanted to be in... And to answer THAT the SCCA REALLY started promoting the TransAm which 911's were in, then out, then in again.........

Through it all, when they let'm race, 911's were winning somewhere...



Ya'know Curt, if I were going to put class lettering on your car, even though the link shows different, I'd probably write C-Prod.............
