I love my 94 GMC Sierra. I often think about buying a new truck but I can't part with this truck. It has a straight bench seat with a 5 speed manual trans on the floor, tons of power and runs great after 250, 000 miles. I've decided to spend the money on restoring it and am getting the speakers replaced next week and then a paint job. When the time comes to rebuild or replace the engine does anyone out there have any recommendations on the difference between a Jasper engine, Chevy crate replacement or just a major rebuild? I would greatly appreciate any advise on restoration issues.
