Stocker rules change? Please

TGould · 11-06-2009, 12:35 PM

The new Stock was established in 1972. Several years ago I went through the NHRA rule books and created a file of the major changes. These are the changes for 1972 - 1979. I won't swamp you with the multitude of changes since then. But, V/S is still 6 and 4 cyl only and W is 4 CYL only .A lot of those great old cars (Buick, Olds, Studebaker) were 22, 23, 24 and 25 lb V8s . So even if NHRA allowed them back in (and they won't for the reasons stated) they would not have a class. But it sure would be neat.

1972: 1963 or newer
Dual exhausts (open during competition)
Pistons (stock) .035 over permitted
Street tires

1973: 1963 or newer
Blueprinting permitted

1974: 1965 or newer
Headers permitted (must retain tailpipe/mufflers)

1975: 1965 or newer
Reground camshaft permitted (stock lift, dur,overlap)
Cool cans permitted
Open headers
Slicks

1976: 1960 or newer
Classes W and X 6 and 4 cyl entries only
Class Y 4 cyl only

1977: No major changes

1978: Electric fuel pump OK (must retain manual pump)
Weigh car with driver (170 lbs added to car weight)
Weight of car can be adjusted + or - 75 lbs to fit the class
Helmets required

1979 : No major chamges

in response to TGould - The car already fits classes in IHRA and NHRA. Check NHRA's classification guide in stock eliminator, the engine is factored at 205 hp and that is for the 180 and 195 hp combinations. Thanks for the input.
