Can someone confirm the bolt head size on the crankshaft on a '73 440. It appears to be a 1 5/16 because my 1 1/4 socket won't fit.
 
All BB mopar crank bolt are 1 1/4. Never have I seen another size.
 
1 1/4 is all I see on stock small block or big block.
 
My 470 stroker was 1 1/8 but it had an aftermarket bolt in it. Is your bolt head good shape or did someone use a 12 point socket with an impact and mess it up? Kim
