1972 PONTIAC - Grand Prix 389

Product Details

1972 Pontiac Grand Prix 389. I purchased a 389 block from a local machine shop, built a new motor including blueprinting/balancing and quite a bit of machine work. The turbo 400 was rebuilt with all heavy duty parts and a Fairbanks manual automatic valve body. I also installed a 3400 stall speed torque converter.To finish off the drive line, I installed a 1965 Chevelle 12bolt rear end with 4:56 gears. This housing is 1" narrower from the brake backing plate to the shock mount. Therefore, allowing for 10" M&H slicks to fit under the fenders. Currently, the GP sits on Pontiac Rally Chrome Wheel Vintiques 15"x10" & 15’x7” wheels with Mickey ThompsonP275x60x15 rear tires. Tires have 1000 miles on them. Keep in mind this GP is built on a Chevelle/GTO frame, so the rear end bolted right in. Plus, the # 1 spark plug sits behind the front spindle, giving the motor about a 15% setback which allows for amazing weight transfer to the rear wheels. The car ran consistent 12.9/109 MPH. I raced it until the early 80's and won many I/SA Class and Top Stock Eliminator awards. I/SA was at the bottom of Top Stock Eliminator, so everyone had to spot me. Built a new home in 84, kids came along and the GP was in climate controlled storage for a number of years. Brought it back home 6 years ago and just used it to cruise and attend shows. Body is very solid with no rust, patches or body filler.
