my trans builder told me that w/ low band apply in a fully auto., one doesn`t need the super sprag. he set mine up that way. does this sound correct? I had a trans explosion once, don`t
want another !!
Using a VB with low band apply greatly reduces the chances of an explosion. I base my ideas on the power level being applied to the trans and the VB used. The OP's brief description of his engine sounds like it will be a real high HP application, that's why I suggested the super sprague. Personal preference is another factor on what guys use. As you see above some guys don't even consider a bolt in sprague important at any power level. I do given all that holds the sprague in place are the splines in the aluminum case and one small set screw. Any bolt in sprague is a big improvement over the stock design and the super sprague not only bolts in but has more rollers for more load capacity. If I knew 100% for sure the rear band will ALWAYS hold the rear drum without any slippage I'd be far more comfortable with using the stock design.
