This was common practice in the old days 50's-60's as HP cams "race cams" were few and far between and engine model selection was very scarce, and also very expensive.
When i built my first hot rod motor a 51 Cadillac bottom end and American Cyl head 56 caddy heads I used a 58 caddy cam with chevy solid lifters, "thanks Mr Duntoff for the Duntoff 30-30 cam and lifters so solids were readily available" used the stock caddy pushrods and rockers from a Studebaker V8 as they were adjustable. Had to use two rocker cover gaskets and dimple the rockers to clear the adjuster screws, set the clearance .004" hot I could tirn the engine a little past 6000 RPM with this setup.
You had to be inventive back then as a dollar issue was prevalent then especially as I was just a teenager in high school then.
