This is the last pure stocker I built. It was built to rules close to what you're talking about. It was a very competitive car in the class. The only way it wouldn't be competitive is if the class allows Camaros then of course the Camaro's low weight, advantageous engine set back will win the day. This car with a full 10 gallon fuel cell and my 250lb but in the seat would cross the scales @ 3450lb.

It was powered by a 360 with magnum exhaust manifolds, E-58 4bbl intake with a class required Rochester 350cfm 2bbl carb and E-58 (.444 lift cam) The transmission was a 727 Torqueflite with a large cooler and deep pan. The rear end was a 9 1/4 with 3.55 gears and welded spider gears. Ran the car in second gear and would turn 6,000rpm at the end of the straights on a 3/8 mile high banked asphalt track. The suspension consisted of MP XHD leaf springs, California Suspension Late B-Body 1.03" torsion bars, factory big block front sway bar with matching rear sway bar. Shocks were from AFCO. The rubber mounts for the k-frame bushings were replaced solid ones as well as solid mounting the torsion bar anchor cross member. Stock brakes with Yellow Stuff pads.

It's strongest feature was it's superior handling. The forward bite from the center of the corner off was amazing for a car running on recapped Good Year Eagle tires (class requirement, Towel City Recaps)
