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 overdrive automatics work great with this powerful combination too. Give us a call to discuss higher performance versions!
