Lonnie at Extreme Automatics he is honest and builds a bad ass transmission. I had his 200r4 which was awesome however Lonnie said if you are making over 700 horse power he recommends a turbo 400. You will not be disappointed!!!!
When it comes to 200s Dave Husek is the man. I’m going lows 10s and can drive it no problem. I also run his 3521 converter. Give Dave a call. Turbobuick performance.
