I have a 72 duster! I’m trying to figure out what the best stall speed would be on my a904 build. I have a supercharged 318 with 8 pounds of boost, msd fuel injected, tire size “245/60r15”, 3:55 position rear, 8.64 compression, 302 head castings, stock valve size but the heads have been ported, not sure on flow numbers, comp cams grind# crs 268h-10

Tight... probably with anti ballooning plates, too. The cam power range is 1500-5800, and boost makes loads of torque. Call PTC, Precision of New Hampton, Ultimate, Dynamic, or any of the modern torque converter companies and have one built based on all the build information. What other mod's have been done to the transmission?
