Despite being down on inches to the 350, the 327 Chevy still lays claim to the most powerful production conventional small-block ever produced, the L84. Rated at 375 hp, the fuel-injected 327 was a high-winding screamer, as satisfying to drive as any big-block.

Why is a 327 better than a 350?

In the vehicle, it’s more of a matter of “gearing” than revs. A 327 with it’s shorter stroke would need shorter gears so it can GET to its revs, where a 350, with its slightly longer stroke and more torque output will pull a little taller gear than the 327 will.

Your 327 has a 4 inch bore, so yes, you could make it a 355 or a 383. (also a 302, for that matter). A 1965 327 has a small journal crank, that is a factory “forged” piece. Your engine builder is making a 355 or a 383 by changing the crankshaft to a longer stroke, and replacing the pistons to match.

Will a 327 crank fit a 350?

The 327 crank will not fit into the 350 block unless it is the post 67 327 crank with the large bearing size. With this crank all you need to do is use regular 327 parts such as pistons. I would use the larger balancer off of a 350 though as it has better dampening qualitys than the 327 balancer.
