Nitrous

I went with 175hp in my Newport years ago. Stock 2bbl 383, srtock convertor, 8 3/4 with 3.55s. The engine had a small MP cam, stock iron intake and AVS, and custom duals. Even used the factory single point distributor with the stock curve in it. Had no special anything except the Carter electric fuel pump and a cheapie regulator at 4.5psi. I wouldnt hesitate to go 150hp on all stock everything if the engine is in good shape. Pull 2° of initial timing out of it for every 50hp and go have fun.
