My historic racing GT engine has got a broken thread in the crankshaft. I therefore need a tap.

I have no idea which threads they are, but someone has got to know..

I need to borrow or buy one!

I think that the thread for the crank bolts (either end) is a 1/2" thread. However I seem to remember that it does not have a std pitch tpi for either UNF or UNC.

In other words its an oddball special, you will have to get the thread gauges out...........

im pretty sure i have heard of people making one before using a standard bolt, cutting slots in it and having it hardened so it works as a tap?!?!?!

And on the 7th day........... God created turbochargers!

Could work.

The crank is going to be mighty difficult to tap whatever you use, just due to the material it is made of.
