I can not find the proper pilot bearing that fits a Blue Print 302(306) that joins with Tremec TKX manual transmission. Outer bearing size 1.38" and inner dimension .58"

I've used a standard Ford Performance M-7600-A pilot bearing on my SBF builds. Have to believe the crankshaft Blue Print is using would be the same outer diameter. For the inner diameter, something doesn't match. The Ford version of the Tremec has a .670" diameter at the pilot bearing. Matches the size of the M-7600-A. A GM version of the TKX is .593" diameter. Close to what you measured. The input shaft lengths are different between the two as well. Are you mounting a GM TXK on your SBF?

BTW, Factory Five doesn't actively monitor this location if you're expecting them to answer.

I have a 302 with a Tremec TKO 600. I got my pilot bearing from American Powertrain PN PBFO-10001. I know Summit sells this bearing as well

Thanks, appreciate the fast reply, you were right, Summit Racing sent me the wrong transmission. Sent the GM TKX back, should get the Ford TKX next week.
