camshaft help

Thanks for the reply, not sure what other info would be helpful regarding horsepower production. Yeah, I wasn't sure if the 5mph gain at the wheels was reasonable on ported 452 heads(I don't have the flow bench #'s)... most of my camshaft knowledge comes from ls1 vehicles... and there an approx 40-50 rwhp gain is not uncommon at all on camshaft swaps with stock heads. I am just trying to get an idea of what to reasonably be able to expect from the swap. I was kind of dissapointed with the performance of the current camshaft, so I wanted to have some realistic goals for this project. Other camshaft suggestions that people think could achieve this goal are very welcome, I am in no way married to the camshaft I listed the specs on previously.
