converter slippage

Thanks for the replies. Thanks for the formulas a/j . And thanks for the comparison Rockin. Going with 4.30 gears. 90% of my racing is 1/8 mile otherwise I would do 4.10s The 7200 is well past power band. I would guess max hp at around 6300 or so. Shift at 6500 to 6600 for best E.T. That's just the max I would want turn the engine. Thanks again.
