So one would have to machine the pilot hole out to except the T .C .snout .

I have a 273 block, and if I use it....it will be with a 318 or 340 crank. I'm pretty much leaning towards building a 318 or 340 though. "Somebody" has a sig line that makes pretty good sense.....lol. Now, back to our regularly scheduled tranny :eek: discussion!
