The EMC (engine masters challenge) is getting a little out of control, and boring ... I love the carb challenge, but now, I'm up for a TMC (transmission masters challenge)...... Next up........ RDC (rear differential challenge)... ;-)

As for TH350, not all 36 element drums are created equal. I would suggest you look for the following items when searching for a drum.

A) While the Ford / diode conversion may be strong, it's very heavy. If you're looking for strength it's ok. For strength and ET savings, not so good.

B) A good drum will have a new inner race installed, not a reground original.

C) The inner race will be pinned in 4 places to keep it from rotating. If the race is just held from rotating by using the factory 2 or 4 half moon lugs, it will work away until it breaks.

D) The best outer race is one with made from new steel and NO oil holes. Stay away from re-heat treated off shore stuff.

Poor accumulator set up, valve body design, and cushion springs won't break intermediate sprags and races. But rather poor sprags and races break. If you have to baby it or cushion it up, you are not using good parts. Put good parts in it and forget about it.
