If you are only looking for around 250kw at the fly then you wont need anywhere near a 286 cam. There should be a smaller roller cam that will get you there without having to run a high stall behind it and you wont need to change your stock manifold either.
If you run too big a cam you will need the stall converter, higher comp and definately a different intake manifold. You would probably be looking at changing the diff ratio also.
For example if you run a 286cam on a 3000rpm stally with the stock manifold your power band will be between 3000rpm and 5000rpm where the manifold rolls off quickly.
Stick with something like a crane roller 889711 214/[email protected] and 464thou lift and it will work between 1600 and 5000rpm which will get you going on the stock manifold. If you run some 1.65 to 1 ratio roller rockers and some basic headwork I think you will be happy.
