I have the opportunity to get the motor out of an 84 buick grand national for 350 dollars. The motor is supposed to be fresh and ready to run. How much would I come out of pocket setting up an intercooler and bigger injectors, headers, and possibly a computer upgrade? The motor will be going in my 85 buick regal. Im putting a 350 turbo bop tranny behind it. Will i need an upgraded computer ? please help?
