Re: olds 442 w-30 stocker
 

Which class would they have run in 70-72?

Re: olds 442 w-30 stocker
 

The 1970 Olds 4-4-2 455/360 HP in 1970 would run G/S.

The 1970 Olds 4-4-2 455/370 HP in 1970 would run in F/S.

Those classes were from 1970/1971.

The cars weighed in at around 3675 lbs.

In 1970 at Dallas, the 1970 Olds 4-4-2 W-30 ran in F/Stock.
And the National Record was 12.01

thank ,Paul ,so it's impossible to run a stock 455 motor , only with headers and slick with a 442 w-30 ,4 speeds and 3.91 with a spectacuar run at 11.79 ,what do you think about that .

Re: olds 442 w-30 stocker
 

hey ,Paul ,, also why olds run in 66 run b/s and olds run f/s in 70

Re: olds 442 w-30 stocker
 

just to chime in ,,you would be hard pressed to run that # ,but there is a racer who runs a green 70-71 olds with a 4 speed set up (350 i think ) that could give you some insight on what you need to do with your car i dont have his info but he runs division 1 ,,if i can find the info i will repost gmonde

Isn't Bureski's W-30 in E/SA?

The weight break factors changed over the years.

1966,,,,,,C/S
1967,,,,,,B/S
1968,,,,,,D/S
1969,,,,,E/S
1970,,,,,F/S

It fell into the 9.50-9.99 wt/hp from 1968 and up.
In 1965, 1966, 1967 the class wt/hp was 9.50 - 10.59
