Solid rollers on a hydraulic roller cam

I know I could go the custom grind route, but with parts availability how long of a wait? Just look at Summit and Jegs and other vendors most everything is out of stock. You can't get a Howards cam anywhere except for maybe a sb Chevy. I guess if I don't like it I could change it later. Get it together fire it up and see how it does. Anyway you look at it 511 ci in an A body w/391 gears and an 8in convertor should be a handful.
