main cap walk

Have the rotating assembly balanced at a reputable shop and install a Hughes girdle. No need for aluminum main caps. I would also install a good balancer. I prefer to use Fluid dampners. Don’t forget to have the clutch/flywheel or flexate balanced also. You should have no cap walk after that.

There's also no need for a girdle. Especially the thin pieces of metal that just basically sit there, like most of these speed shops sell. You can't convince me they do anything to actually improve the structural integrity of the block. Snake oil for people to spend their money on... All the necessary machine work done well, with studs throughout combined with a correct tune is all you need, from my experience.
