Yes, he did some porting and bowl work and they were shaved a little bit but nothing real drastic. He's running a 3.42 posi in a "hybrid" 10 bolt rearend with 12 bolt axles. I added a pic of the "Bird before he started on it. I'm maintaining the photo files of everything he's done to it since he doesn't have a computer. My 72 RS has a 2.41 posi in it, too but I actually liked it because I could afford to drive it every day. It still managed 14.50s through the quarter. The 60' times were horrible since it would either bog or roast the tires depending on how I tried to leave (4 speed). Once I got it moving and hooked, it would freight train the big end and go through the traps at 115-117... Unfortunately, that motor didn't come home after the car was stolen and recovered, but I'm building another one just like it to go back in. The machine work is done and most of the parts are here. Just needs to be assembled... Too many projects and not enough time. I'm spread pretty thin... Recovered after 10 months in the wind... .
