is it worth changing intakes?

OP
Do you realize that the Voodoo 701 has nearly identical advertised duration specs to the stock 360 2bbl cam? And the .050s may be only 4 or 5 degrees better for high performance.
And do you also realize that those 4 or 5 degrees of duration will steal a bit of already low, low-rpm performance?
Can you afford that in your 18footer?
