Is a Chevy 327 a good motor?

Chevy 327 engines are some of the best ever produced. They’ve powered everything from boats, hot rods, sprint cars, pickups with campers, and drag race race cars. I was in awe, reading Hot Rod Magazine in the sixties, when they described getting 1 horsepower per cubic inch out of the 327.

How much horsepower does a Chevy 327 have?

The 327-cubic-inch small-block reached its peak power rating in 1965: 365 horsepower with a four-barrel Holley carburetor or 375 (1.15 hp/cu-in) with the Rochester Ram-Jet fuel injection system. By mid-1965, the 327 played second fiddle to the 396-cubic-inch big block that debuted in the Corvette.

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.

What is the difference between a 327 and a 350?

The difference in the displacement comes from the crankshaft stroke. The 327 uses a 3.25 inch stroke, where the 350 uses a longer 3.48 inch stroke(thats what makes it bigger). Depending on the year of the block, the biggest difference in the block itself is the main journal size.

Rated at 375 hp, the fuel-injected 327 was a high-winding screamer, as satisfying to drive as any big-block. At the other end of the spectrum, the 327 was also offered at much more pedestrian power levels, as low as 210 hp (gross).

The L31 Vortec heads will bolt onto any Gen I small block. Your 327 isn’t any different than any other Gen I small block built from 1955 thru 2002. The main difference with using the Vortec heads is the different intake bolt pattern as already mentioned.

Bill, 350 heads will work on your 327. Avoid 305 heads like the plague, though. You will want to find some with similar size combustion chamber and valve size/port size in order to keep at least the same power output your 327 had when new.

Will a 327 crank fit a 350?

350 and 327 have the same bore but different strokes (3.48-3.25) so putting a 327 crank in a 350 will do nothing but make it a 327.
