Piston pin heights.
How accurate are the advertised pin heights among the various piston manufacturers? I know the old TRW's were usually right on the gnat's behind but not so the Speed-Pro TRW replacements of the same PN. I bought Speed Pro "TRW" forged pistons a few years ago, the catalog said pin height was 1.560, they measured 1.540. I would expect that of cast rebuilder pistons but not a supposedly "High Performance" part. Can you believe ANY of them and if so WHO? Thanks.
