Recently purchased a 426 hemi block. It's missing the cross-bolts. What is the correct length used on the stock block mains? Is a lock washer used on the bolt? Also, are lock washers used on all main cap bolts? If so I'm missing some. Thanks

The stock Hemi side bolts i just measured are 2.700 UHL and use a flat washer.

make sure that you use grade 8 or better for all the flat washers, both mains and side tie bolts
