1985 Pontiac Grand Prix Base Coupe 2-Door 5.0L

Bought this car as a project car from my uncle about a year ago, but due to the fact that my family just doubled in size, need to get a different vehicle. Less than 3,000 miles on engine, transmission and tires, straight body, 350 / 5.7 L, TH 350 TCI transmission, 1700 stall, stage 2 TCI shfit kit, new window motors, needs door panels reinstalled and needs a headliner reinstalled and radio, 350 GM crate engine, Edelbrock carb and intake, Edelbrock dress up kit, Hooker headers, long tubes, 2 1/2" true dual exhaust, single chamber race muffler, aluminum rims, engine has a noise, i think it needs valve adjustment, work in progress just needs some TLC,, vehicle being sold AS IS, ALL SALES FINAL, PAYMENT MUST BE RECEIVED WITHIN 3 DAYS, BUYER / WINNER RESPONSIBLE FOR PAYMENT AND ARRANGEMENT OF TRANSPORTATION OF VEHICLE, mileage on body is 155,000 +, less than 3,000 miles on engine UPDATE: I did a valve adjustment, didn't help... the more I listen to it and hear it, the more it seems like it's a flexplate. It quiets up when you stall it up. A flex - plate that can be picked up at a local parts store for a reasonable amount. With that being said, there is no engine noise, the flexplate is making a racket which can be mistaken for engine noise. Spouse and I both need to have vehicle gone ASAP as our children are our top priority and going from 2 to 4 is giving us a sense of urgency.
