Try Thai food. They make Texas BBQ as challenging as a Yankee boiled dinner.

I think the volcano butt is cast as part of the crank so there should no parting line.

The stub doesn't need to come off, but you need to make sure the pilot HOLE is in the end of the crank and deep enough for the end of the input shaft of the newer model transmission, or the "nose" on the torque converter if an auto.

I guess with the added cost you are, "losing you A$$ on that one." (meaning both literally (the "volcano butt") and financially)

From what I have been advised, the pilot stub does need to come off. Crank is in Sun Valley getting "De-butted". Thank you for the advice. Jim

NICE. Thanks for solid info! So the pilot bush hole is the same and all? So I take it the torque converter does not fit over the volcano. |

I have a 61 American flat head with auto trans. Picked up a donor OHV to rebuild and ran into the crank question. The FH that came out of the vehicle had a flat crank but the donor had a volcano. The donor had come from a manual. After posting in this forum and input from Frank and Tom I made the decision to have the volcano machined off to match the crank I pulled out. I would post the cad drawing with measurements I gave to the machine shop but I am still too new to post pics.

I've only seen the "volcano" crank used with early autos, but I don't have a lot of experience with pre 61 models, and no autos prior to 63. The 61 and 62 Americans I've had in the past had manual trannys and flat cranks.

To stir in some more mud to this cloudy pot, I had to use a volcano adapter on my 1963 flat-butt crank to use the ModernDriveLines T5 adapter. If anyone needs it all the dimensions are fairly exhaustively documented on my web page.
What Frank says certainly jibes with everything I've seen (fwiw). But is it as simple as, pre-63 (62 and older) are volcano butts, always? If so, then what's the deal with transmissions and bells, as all evidence is that EVERY T96 has a 7.125" long input shaft with 3/4" pilot.
