Jim, the block had already been completely machined and run in the States. I did not do any additional machining except for hand detailing of all parts prior to balancing (incl block webs).

When I received the engine it already had a girdle on it however I swapped mine from the 5.0 onto the 347 as my was 3/8 thick Vs the skinny one that came with the 347 (1/4" perhaps).

The style of girdle that I run has spacers that go between the maincaps and the underside of the girdle. I usually pull up 1 and 5 main studs to 40 - 50 ftlbs and check for any significant gap between the girdle and main caps at 2,3 & 4 to check alignment. The thicker the girdle the more important this would be so that you didnt preload the block. This could cause premature web cracking otherwise.

Kel.
