Trying to get Power out of a 225

^^^^^^^^I agree the proper torque converter is a must.The modified slants that I had came alive in the 3000-3200 range.My last street slant we made fun of it with a 2200 rpm converter.It would leave the line like a super gas car crawling out of the hole then coming alive 60+ feet out (with 2.94 gears) A 8'' 5000 rpm converter and 4 .10 gears sure made a difference..
