Have a L28 - F54 block with an E31 at 13:5 compression, cosworth pistons, etc. etc. Broke the crank (right behind the last journal, so, the head is intact) and the #6 main cap, block has some blueing due to heat in that one journal. Now the question is, without having to toss an extremely well prepped block, what are my options? Having trouble locating a main cap to begin with, so I'm thinking of making 1,2,3,5 & 6 main caps of billet steel. If someone has a main cap, that would be great as the plan then would be to shot peen all the caps, line bore, cross-drill and balance the crank. Head would get new valves, springs, etc.
