Early 60's to Mid 70's Racing Classes ( "stock" body )

Is anyone here knowledgeable about the various stock-bodied racing classes from c.1960 - c.1976 ? I know there was :

- Super Stock
- F/X
- O/SS
- Stock ( e.g. , D-Stock )
- Modified Production
- S/FX
- Pro Stock ( '70 & later ? )
- ???

I'm building a couple of 1/25 scale race cars, and am wondering what class(es) they'd qualify for . If anyone has a rule book or any other literature they can share , that'd be great !
I know that some of these classes were super-strict , whereas some were more easy-going ( lots of grey areas ) .

Here's what I'm building :

- 1968 Hemi Dart : This one's going to be a GTS model with a crossram Hemi , T-Flite , Dana 60 . Full interior .
This is the new kit from Revell-Monogram ; it's based upon the '68 GTS / GSS , but has certain Hurst-Hemi parts included ( however , it has the GTS' upholstery pattern and door panels , instead of the 270 model's pattern ) .
I'm thinking Modified Production , but am not sure .

- 1969 Barracuda 383 : Old MPC-come-AMT kit , representing a "BH29H9B" car .
Stock 383 ( with power steering ) , 4 speed , 8.75 diff . Full interior .
C/Stock ?

Thanks much !


I began drag racing in the mid 60's and still race today. I raced everything from a P/S 283/2spd Pontiac to an A/GS Anglia back in the 60's and 70's. In the 80's & 90's - Pro Street Dakota. 2003 and on SS/AH '68 Cuda


Your '68 Hemi Dart is a SS/A or B car depending on NHRA's mood at the time.(SS/AH today) SS was the only class they were built for. In altered wheel base form it would be - A/FX, and Supercharged altered wheelbase - AA/FX. The original Hurst cars came with the up level interior so you are OK there.

The '68 Cuda 383 would fit in C or D Stock, SS/D , or D or E/ MP so the choice is pretty much yours.

Have fun with your builds.
