| Are you using ARP studs?
If so they have a much greater clamping force for the same torque setting as the standard bolts. I believe that if you go for 75 ftlbs that you can get away without inline boring the mains using studs but you'd better wait for more replies on that one!
Someone like Russell RAM can give you a lot more help.
You could try just fitting one main bearing cap at a time with the engine inverted so the crank won't fall out, that way you could see if its just one bearing or all of them. You could try some plasti gauge so that you can check for the right clearance.
I recon that without the pistons and rods fitted the crank should be pretty free to spin, especially if you've oiled up the journals. Its not worth risking going any futher until you are sure that its right othewise at best it will play on your mind and at worsed you will chew up the crank!
You have fitted the right caps on to the right bearings?
Cheers,
Pete
