horsepower estimates.

By the way the mopar springs we tested was for a project my buddy is working on. Thought about calling comp, but if those springs are that far off it makes me nervous. The only reason I bought a complete set I was gonna use J heads, but decided they needed a lot of work. The last valve job done on the j head was cut way to deep on the intake's and was gonna have to step up the size to get them right.
