4 speed VS Automatic

I'll bet with that big block and all the torque it puts out ,if you gear it right you will run low 10's maybe see a high 9. If you would of had a higher stall in the 727 you would of liked it more . I run a 8in. converter it stalls at 5200. what is fun to do is to leave at idle and mash it to floor and the stall lets it jump to 5200 and she will pick tires about 8in. off. know getting back to 4 spd. you can leave at any rpm. this could help et. I used a V gate in line shifter in my modified prod. car, it worked good. the car was a 1956 chev running a 301 sb. 557 gears in rear, and a munsie 4 spd, best time at Bandemeres mile high in Denver, was 10.19 back in 1978 I had to leave the line at 8000 rpm's or it would boog. shifted at 10000rpm's it was fun Good luck Gary:cheers:
