Samwise,
Having gone through the replacement of a TH350 with an SM465 (same as Deac, I suspect), I can say that swapping to a 700-R4 or 200-4R would have been much easier. The 200-4R can swap with the TH350 without any driveshaft mods, just crossmember mods.
One thing to keep in mind is a 3.73 rear with the tranny Mike is running equates to a 2.73 ratio in overdrive. With that in mind, I'm planning on swapping my rear gears. With the SM465 running into 2.73 rear gears, the 1st gear ratio is 17.9:1. With Mike's 4 speed, 1st gear into a 3.73 rear will be 11.5:1.
So, in theory at least, the SM465 can offer the same range and be bulletproof at the same time. At least that's what I'm hopin'
Oh, and howdy again guys. I've been off the board for over a year, but my user account is still active. Don't worry, I didn't stray into bent-eight land, but other priorities kept me away from the inline.
