Where would be a good place to take the exhaust manifolds to have them smoothed out on the inside? Or should I just use a drimil tool myself? Thanks for the info on the elec. fan. I want to go with an electric to save a few HP, since I'm not using the headers. I'm not racing the car, but I would like it to be as strong a runner as I can on a teachers budget. : ) Thanks for the good ideas!
