Motor & Quickchange Oils?

[Jim in Upstate NY]

I dragged my old roadster out of the barn after sitting for 5 years or so. I live in Upstate NY so I only will be driving it till the weather gets cold. My Halibrand V8 Quickchange dripped a little gear oil over the years so I drained it down and can't remember what gear oil I use to run. (#1) What's a good weight gear oil (don't run it hard) and (#2) What's a good weight motor oil for my Flathead. I think I use to run straight 30 weight oil. Thanks, Jim

WOW! Hard to believe all the experts on this site can't answer what type of oils to run in my Flathead. I'll try NAPA!

Halibrand suggested Valvoline 80/90 synthetic blend for my V8 Q/C. As for the engine, a good 10W30 is all a flathead in good shape needs, or 20W50 if it's a liittle loose. IMO.
