So I messaged Mike at MRL about those main caps and this was his response.

Quote:

We no longer make them. The company I was working with has since gone under and I can not find anyone who will make them for a reasonable price, as of yet. Sorry.

BTW, they have been field tested to 700hp in a stock 360 block, and its still going strong to this day. That was back in 2009.



So that idea is out the window.
