I think a T-5 or AX-15 would be the only way to go on an inline stroker with those kind of numbers. The 505 Performance kit and massive turbo are definitely where the power comes from in this build. I'm only building up to 4.7L by mixing parts from the original 258 and hoping for numbers that top out around 250hp/300ft-lb range on straight MPFI. It's the thought of bolting up an automatic that seems scary. :P
Ummm time to win the lottery?
T5 is not that strong in the 4x4 version. My bone stock 4.2 killed one at 40K and another at 70K (when I got the truck)
Automatics always have a higher torque rating than an equivalent manual transmission. Always.
A 727 is rated the same as a NV4500. The NV4500 is a beast that weighs much much more than a 727. The TF998 is stronger than an NV3550. The TF904 is stronger than a World Class T5. Stickshifts do not have impressive torque ratings but they have their own set of advantages.
One main advantage is that a stickshift can be cycled from forward to reverse quickly. That kills automatics especially in plow trucks.
You can mod the auto to speed up between forward and reverse. I've done it several times with 727s. Valve body mods, especially reverse shift pattern help a lot.
That is something I'll have to look into next time I'm inside one. If you remember any details it is well appreciated Carnuck.
A quick fix is using a Chev small headbolt in the accumulator above the valvebody (change the shift linkage seal while you're at it)
