I finally got my car running and to the track
It has 4.57s. The car has an A-518 overdrive trans. When I built it, I was thinking race it with three speeds like it's a regular 727 and use the O/D to cruise the street but as soon as I made a pass at the track the car was up against the. 6500 rev limiter a good 2-300 ft before the finish line and it went through the traps @109 popping and spitting. The guy who did my trans had told me that the O/D in the 518 can handle full power so on the other runs I used it and it worked great, hit the O/D at 6000 and the car just frieght trains through the traps pulling hard. The O/D works great on the highway also. 3000 rpm is just over 60 mph. I also have a PTC 9.5 inch 4000 converter which is working absolutely perfect with this combo.
