I bet that he can regrind it for you, maybe on a smaller base circle, or provide a warranty adjustment deal on a nice, similar grind.
I just talked to Isky about a regrind of one of their special grinds...very very reasonable. Includes new parkerizing and the whole shebang....like new.
But your Crane sounds tough, boy did they help a lot of FE's make big numbers back when, and today.
Heck, you are a NHRA past Champ, and record holder, and a legendary terror of the quarter mile, I can't believe that some Cam guy is not sponsoring you ? Ask them? You could help any grinder sell plenty of bumpsticks if you ask me...?
