After searching and screaming and hollering, I have finally decided on the Chevy 350 that I want to swap into my 1984 Buick Regal. I want to install the "SBC Turbo Fire " from the 1969-1980 Chevy Impalas. I dont know how rare this engine is but I do know that the Horsepower and Torque are exactly what I have been looking for. What do you guys think?
