How can I tell if I have a 327 Chevy engine?
Check the numbers on the deck that were stamped on the engine right before it went into the car. Look up the 2 or 3 letter suffix to find out what it is and what it left the factory in. Not all engines have these numbers. The engine in my roadster could either be a 327 or a 350 just going by the block casting number.

What years did Chevy make the 327?
Although the 327 was eventually superseded by the 350 across the entire Chevrolet product line, the intermediate displacement 327 was used in just about every Chevy on the market between 1962 and 1969, including the Malibu, Impala, El Camino, Chevelle, Chevy II and 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. … Never underestimate the importance of gearing.
Is the 5.3 Chevy engine any good?
The Vortec 5.3 is widely regarded as extremely reliable, with most engines having a lifespan within the 200k-300k mileage range. I own a 2002 Suburban with the LM7 engine in it and it’s running strong at 220k miles with virtually zero engine issues over my course of ownership.
How do you tell the difference between a 327 and 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.
How do you tell if it’s a 327 or 350?

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).
Will 327 heads fit on a 350?
They are perfect for a 350. Both the 327 and the 350 have a 4″ bore so they like the same heads. Old heads like that will have softer valve seats, so if you want them to last a long time, you should either replace the seats or run leaded gas in the engine.
