How good is the stock 94 cobra cam?

[90mustangfan]

How good is the stock cobra cam on a 94' cobra compared to say e303, tfs stage 1, crane 2030, or other after market cams, not custom cams, but other aftermarket. For a meduim H/I, full bolt-ons application. AFR's 165's and performer intake, with stock cobra cam. Or on a lightly boosted 5-6 psi with h/i and stock cobra cam...some people Ive talked to say the stock cam is pretty darn good for H/I, or blower app's. pretty much good enough where its not worth the gain to really switch?

umm call me wrong but isnt the cobra cam the exact same as a regualar 5.0 cam? I thought it was the rockers only being diffeernt in the valve train.
