Re: 1965 BB/Stock,,,,,,,,,,,,,,,???
Pete,
1965 A/Stock = 8.70 to 9.49 Wt./Hp...........(Would have been changed to 8.30 to 8.89 Wt/Hp) The A/Stock cars in 1965 were running; A/S = 12.70's A/SA = 12.95's 1965 B/Stock = 9.50 to 10.59 Wt./Hp. factor.....(Would have been changed to 9.50 to 10.09 Wt/Hp) Also known as, the 'factory' general street-musclecar class The B/Stock cars in 1965, were running; B/S = 13.00's B/SA = 13.30's The 1965 proposal would have had the BB/Stock cars (1965 only cars) with a 8.90 to 9.49 Wt./Hp. factor,,,, A 'dealer prepared' street musclecar, with a big-body car stock performance engine,,,, Which would have put the; 1965 Buick GS,,,,,,,,,,,,,,, 425/380 HP,,,,,,(3430 lbs.),,,,,,,9.03 Wt/Hp 1965 Oldsmoblie 4-4-2,,,425/370 HP,,,,,(3395 lbs.),,,,,,,,9.25 Wt/Hp 1965 Pontiac GTO,,,,,,,,,,421/376 HP,,,,,,(3467 lbs.),,,,,,,9.25 Wt/Hp All within a great competitive class,,,,with cubic inches, horsepower and weight pretty much equal.... 1965 Elapsed Times,,,,,,,, probably in the 12.85 range,,,, Last edited by Paul Ceasrine; 12-28-2011 at 08:09 AM. |

1965,,,,,,,BB/S
The class was for 'intermediate cars only',,, So the 65' Malibu SS 396/375 HP could qualify for BB/S. Car Weight; #3350 lbs. Wt/Hp = 8.93 Class; BB/S Chevelle Malibu SS396,,,,(w/Z-16 Option and 396/375 HP L-37 Engine Code). With only 201 built (production numbers), back in 1965 I don't think they could run in A/Stock.
