If you are looking to upgrade that old, tired Chevy 350 and bolt in extra horsepower, this aluminum head stroker crate engine by Tuff Dawg Engines would be an EXCELLENT choice! With 440HP @ 5250rpm and 480 ft lbs of torque @ 4500rpm it has a fairly smooth idle with a lope, and good all around power. It works well with either a manual or automatic transmission. This TPI fuel injection engine will run on leaded or unleaded premium pump fuel and pass emissions.
