SB aluminum 1 piece mains/girdle

The problem with that is is it just adds weight. This stuff has been tested over and over and it does nothing. In fact it can be detrimental in that it moves the load around the block to where it shouldn’t be. Ritter is still making blocks. I’d save my money and buy that block before I ever did a girdle.

Not to mention power loss, right? Y block designs are known for challenges with controlling the oil slung off the crankshaft, and makes scrapers less effective as well. BBM and FE motor builders have talked about this quite a lot from what I've seen.
