NASCAR history question - Spidey I think you are my dude here

[milner351]

I stopped caring about the time "stock car" became an oxymoron, the old stuff is cool. It's a damned shame all the sanctioning bodies have turned nearly every form of racing into an advertising money game.

Always wanted to know when they went to aluminum heads, when valve angles went away from production, race blocks started to be used, etc.

This information is from my memory working in the race engine field doing SCCA, IMSA, and Nascar engines during that time period.
The factory "bow tie" blocks became available ~1980. The alloy heads were in wide spread use ~1983. It was 1984 that Pontiac had Brodex make them a head with a casting number to be legal and ~1985 that some engine buildes started to "lean" the bank angles from the production 23 degrees to about 21 degrees. Next came the 18 degree heads in 1987 and the race was on.....

And Brian, dual carbs were long gone by 1969, as mentioned.

Thanks Spidy..... This symbol ~ means around, as in around 1983. Oh and I also said "wide spread use". But thanks for the input. ;)

I would suggest that it was racers that turned it into an advertising money game. It was racers that pushed the technology. "Win on Sunday, sell on Monday."

I hope you had the chance to read the Yunick autobiographies that I bequethed to the book club.

If I am not mistaken, the supply is created by the demand.
