363" Cruiser 440hpThe 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 ...

427" Cobra 560hpThe quick-revving 427" Cobra is a performance engine that is not for the faint of heart. Because it is based on a 351" Windsor race block, it is approximately 140 pounds lighter than the older big blocks. From the block, to the crank, to the rods, to the induction system, the 427" Cobra is built to be an all-conquering powerhouse, yet is still a street engine that runs on 91-octane pump gas. With its lumpy hydraulic roller cam, the exhaust note is one that says “don’t mess with me“, and has t...
