The Smeding Performance 347 Extreme is the smallest of all our stroker engines, yet has more power than some of its bigger brothers and it has became one of our most popular stroker engines. You’d 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 302s due to the longer stroke which greatly increases the low rpm torque. With all of our years of experience building strokers we have honed this combination to perfection. All the right parts are mated together to make one of the best, and most easily driveable power combinations available for Ford owners today. With its extremely wide power band, the 347 Extreme works very well in front of stick transmissions, as well as automatics, even ones with overdrive. With loads of options available, like different induction systems, and our polish package, you can personalize your 347 Extreme at will.
