I work on three different strip/street V8/RWD bracket cars. What are the qualities or specifications I should be looking for in choosing an engine oil? All three are single carburetor, hydraulic flat tappet camshaft engines. Ideally the engines get torn down and inspected every other season. An average season is around 150 1/8th mile passes during the heat of summer.
So the engines are a 406 small block Chevrolet, a 427 small block Ford, and a 440 big block Dodge. Changing oil often is not a concern; keeping expensive crankshafts, pistons, and valve trains in good shape is the goal. Maximum engine rpm is 6500 for all three combinations.
Currently using, depending on each engine owner's favorites, 10/30 VR1 and 20/50 Brad Penn. None of these engines have ever had major failures but I feel I'm always guessing on what to put in the crankcases.
Thanks ahead of time for your thoughts.
