8 inch converter questions...

I agree there is more to it than just putting a convertor in, many factors are considered when building the convertor for your application, rear gear size, cam lift, carb size, trans brake or not etc. I use Lenny at Ultimate for my convertors he has done the T/A 8 inch in my car now, my spare 8 inch and the lock up convertor in my D150 and all are excellent! Quick story.... about two years ago I was considering a store bought 11 inch convertor for my low 15 second 5.2 D150 I called Lenny and he said send me your stock lock up convertor, I did , he redid it and i picked up over a tenth in 60 ft, now going 2.0s in 60 ft compared to high 2. teens it used to .
