Even though it is the little brother of the 427" Cobra, the Smeding Performance 363" Cobra, when provoked, strikes with a vengeance. With a broad, kick-in-the-pants torque band and brutish horsepower, this pump-gas-friendly powerhouse gets with the program. Using all premium parts in a proven combination, along with precise machining, careful hand-assembly, and then broken-in, tuned and tested on our in-house dyno, you are guaranteed the power we say it makes.

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 ...

With the knock-out punch of a big-block in a small-block package, this engine has become our most popular Chevy stroker. Gobs of tire-frying low end torque and a very noticeable exhaust thump are the signature for this engine. Do not let the big power numbers scare you, this is a street engine through and through with some bad boy thrown into the mix. 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...

This unit is so clean and simple that those who are familiar with the classic Weber setup often confuse it with our modern fuel ...

The 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...
