TH 400 vs 350 vs 200 metric

Thats not true, you just need the right converter by the right company. The wrong converter is worth 3 10s the wrong way. Don't waste your time putting aluminum drums in a 400. Buy a good 350 or the right 200. A 200 will live fine behind a 455 if you have the turbo input converson, with a good pump and stator support.
