Erson Cam >> good with lots of compression ?

Getting around to building my second 273 engine that came up with rod knock.
I'm thinking about using this erson SOLID cam again ......... only difference is going with high compression 10.5:1 stock dome pistons . closed chamber heads again ld4b headers 4 speed. This cam was used with 4 relief pistons before it came up with a rod knock. Probally had around 9.1 compression approx. It actually ran pretty good . just wondering what you guys think if I were to put this cam back in another engine and give it some 10.5 compression. another 273 block is ready to assemble.
