Quote: Anyone in the upper 12s with a stock 440 on pump gas?
...depends what you mean by "stock". If you mean "as rolled off the assy line" then I'm gonna say no. Certainly the low 12 sec. cars are running too much compression (combined with the cam's high cranking pressures as well as the detonation prone stock cast 906 heads) to run on pump gas. The general consensus of the Ronnie Sox A12 RR test was that the car was "tweeked". The fact that none of the other 440-6 road tests from "back in the day" are in the 12's would seem to support this contention.
According to "them in the know" it would be possible to run a lower compression, Pure Stock legal, 440-6 that should break into the 12's and run on pump gas, but you are definitely not going to run with the top dogs in PS at that compression level.
