How did an 69 Chevelle 427/425 automatic make AA? The 69 Chevelle 427/425 automatic is a natural B car. We even asked if using aluminum heads to make the HP factor 435 would make it a natural A car with an automatic, and were told "no". The automatic has been a natural B car for as long as I can remember, back to when Harry Vineyard ran one back in the eighties and early nineties.Harry drove the car with an automatic in B/SA, and it was a killer. They put the 4 speed in and Tucker Parrish drove it in A/S, and it was just as wicked. I think Kevin Borgstrom put the 4 speed in his beautiful green Yenko clone just to run AA.
