I think my 727 is fried. Now I'm at a crossroads...

When you replaced the pan, did you refill the transmission per the directions in the FSM or add all the fluid at once?

If added all at once, a lot of it will puke out the vent hole inside the bell.

And after puking all that fluid out, it would be too low to operate normally.
I should've clarified, I replaced the engine oil pan, not the transmission fluid pan. I thought perhaps I had a leak and some was dripping onto the exhaust.

Why would you have to build the engine differently? You got me on that one.
I honestly don't know. I've read here that when folks are planning their builds, manual vs automatic transmission is a consideration when choosing the cam.
