Ok I have found a crank on ebay and it is now at Aircraft specialties getting overhauled and they said it did not "pass" the SB505. Now I have read this service Bulletin and from what I read the only way to "fail" would be to have pits or corrosion deeper than the 1.91 inner diameter allowed. My ID measured 1.919 and therefor is certifyable however they will not certify it to more than 150hp.....anyone been there done that? I surely do not want to do something unsafe but, first off is there any mechanical reasoning to this? or is it just the lawers telling them to tag it that way so if/when I put the high compression pistons in they have no liability with it.
Does anyone know what the ID was to start with?
All in all I think I got a good deal on the crank but I am curious if I am going to have a problem or should be concerned if I get this engine to make 170+hp.
