Maybe, maybe not. Have a think about what he says here:
"Problem is, that cam won because it was the best "Band-Aid" for the mismatched parts. Put properly sized heads, manifold and carb on it, and it's no longer the best cam, and most likely not the cam the winner would design.
When I asked Eric about the manifold and carb being too big, he said they weren't because they made the most power with the Texas Speed cam he was testing. That's when I knew he was in over his head. That's like putting in a cam with too much duration, and when you find out it likes 42 degrees of spark, you assume the same engine with a much shorter cam needs 42 degrees of spark."
