I have 54, 45, 37, 33, 28, 25 and 24 tooth sprockets! I plan on using torque converter. I think with the tav, I could go with a smaller sprocket and still have low end power! I want to get as quick and fast as possible with the governor installed. I also plan on building a nasty little hemi predator for it! Rear disc brakes are in the works right now!
