Don't panic yet. I have had both a K1 crank and an Eagle crank and a friend had an Eagle crank with issues. We both just took a flapper wheel ( sanding wheel ) on a die grinder and made a few passes to remove some side clearance. Not much is needed so don't go crazy. It worked for both of us.

ok I wont panic but the converter is not going into the crank far enough not the fit on the side. I never bought a NEW Eagle crank in my life because of continued issues like this, and never will. But they did teach me a valuable lesson and that is to check EVERYTHING. I'm changing a gearset in my powerglide today and installing a new higher stall converter. The first thing I checked this morning was that the new converter engaged the pump correctly. It did.

I had same problem. I Put .030 shims between flexplate and converter. Also made .040 shim to go between crank and flexplate.
PSO headed 632 from MM. Cracked cylinder, loose valve seats, low oil pressure, low cylinder pressure. ..... Now its a door stop....

PTC wants between .125 and .187 to move the vert forward to crank to help with pump drive.I would have to run a .125 mid plate to do that and may be the design of the vert.

Are there any standard dimensions for the depth of the crank pilot hole and the length of the converter snout? PTC said they would get back with me on that measurement

IMHO 90% of thrust bearing failures are caused by this.
Kevin My bad for being in a hurry. Here is my flex plate shield,I could move the engine forward the .090[midplate thickness]cee-4036 The shield sits right on the firewall with no extra room when running.I move it forward to get it out.

The midplate only moves the TC back not solving the nose problem. The Eagle crank had .251flange to pilot,.635 deep pilot The 440source has .248 flange to pilot and .641 deep pilot
