Back to back comparison of Th350 and Metric 200???

If your going to spend money on a really good T350, lightning, low pressure, pump and VB, aluminum drums throughout, you might as well buy a pro trans.
The 200 close to stock form, is at least a .10 faster than a 350, unless the 350 gets 4k worth of upgrades.

There are 200's in everything from comp cars to stockers these days. They are very reliable, and durable. For a lower power stocker it should be a win - win.
