I had an 87, 302, GT40P heads with valve job, GT40/Explorer intake, E cam, 1.7 rockers, u/d pulleys, shorty headers, o/r prochamber, mac flowpath catback, 70mm TB and EGR plate, CAI, MSD 6AL ignition, a/c delete, 75mm MAF, 19# injectors, 5 speed, 3.73s, lots of cooling mods like an electric fan, 180* tstat. Untuned, and with a stock MAF and TB, the car made 260/280 on the dyno. Once I added the MAF and TB, the car really woke up and felt far less restricted. I wouldn't be suprised to see that if it had been properly tuned by a shop that the car would have made closer to 300/300. The a/f and timing were way off on the dyno, it was run the day after we finished the motor and had tuned by a timing light, our nose, and the fact that we no longer heard pinging lol....
