Oversized oil pan?

here is a link to a sale article from Slant six.org the slant six drag race guy selling the windage trays. He also sells a crank scraper made for the slant six.

Windage Trays - Interest - Slant Six Forum

Rick C got into the slant six windage tray and crank scraper business after Mike Jeffery, another long term slant six drag racer and former drag racing National Record holder retired from making and selling slant six windage trays and crank scrapers. Mike made and sold windage trays and crank scrapers for maybe thirty years or so.

A link to the I-J two piece slant six crank scraper. This set of scrapers work from both sides of the pan rail to wipe the crank counterweights. I have this model scraper in the slant six in my 68 Barracuda.
