I put a 10-1 Cad 509 in an 87 442. I used a Northern aluminum that I bought new for 179. Big bearing motors generate a lot more heat at higher rpms. Use a headered engine oil cooler and cool the problem directly. Like Bob did to help keep cool & extend the life of his oil / big bearing Olds 455. http://WWW.robertpowersmotorsports.com
BTW I used a 3.73 for optimum acceleration for my setup but with a built 200-R4 & a lock up converter for a final drive ratio of 2.49. This made for cool running on the interstate & good hwy mileage.
Great job on the car and documentation btw. Very cool.

In the muscle car era if it had a small block it was your moms car.
