Hello all......new guy here. I bought a 1984 "hot-air" Grand National with a buddy of mine. We are brand new to the GN scene and have a few questions. First, the car was bought not running, so we're pulling the motor for possible re-build....how strong are the '84 bottom ends?...should we beef anything up? Also the turbo impeller threw some blades, so it will be re-built, or replaced....if so, what with?...(we want about 350-400 hp out of it.) We also have a Turbo-Motion intercooler kit for the car (good or poor?)....should it go on, or are there better ones? Any extra advice about the '84 model year would be greatly appriciated. Thanks in advance. Randy and Brian.
