Ok, so I need to figure out what transmission I need to build. I am building a 572 hemi with 9.5-1 compression. I dont have enough money to build a 18 spline and eventually want to do the Passon 5 speed. I have a Dana with 3.55 gears, so do I combine the 2 transmissions and build a close ratio 23 spline or wide ratio? Tim
