363" Cruiser 400hp
The Smeding Performance 363" Cruiser is the smallest of all our stroker engines, yet has more power than some of its bigger brothers. You would think that a small-block with over 400 horsepower would drive like a high-strung drag race engine wouldn't you? Surprise, not so! This very efficient stroker has better drivability and higher vacuum than most lesser powered 302"s due to the longer stroke which greatly increases the low rpm torque. With all of our years of experience building strokers ...

This engine produces a very broad, strong torque curve that is good not only for cruising, but for high performance as well. Power brakes and o...
