    No Power to Speedometer?

    NP241 Strength?

    I have a np241 out of an 89 GMC. I'm wondering how strong it is for what abuse I'm going to use it for. The truck has a 350 that I plan on putting a cam, heads, headers, and intake on, so I'm hoping for around 350-400 crank horsepower or maybe even more. I know I'm going to have to build the...
