As for the iron block deal, I think Shelby was buying anything he could and some of it was used, I think that is were the inflated machine shop cost came from.(correct me if I'm wrong)

As for his own aluminum block......All the bores in my block (CSX 124) had to be staightened....one bore was barrel shaped over .002. The pistons had to be ordered in a custom oversize of 4.253 just to make it work. Shelby stuff is nice but if you look at anything close enough you will find flaws.

If you by a CSX block, I would advise you not take there word as gospel and have a good machinist check it out for you.
