The larger sized main journal diameters of the 1968 327 small-block, 2.450, are the exact size of the later 350 small-block. The difference between the two is the length of stroke on the crank, 3.250 for the 327 and 3.484 for the 350.

What was the highest horsepower 327?

For 1965, Chevrolet introduced the L79 327. Rated at 350 horsepower with its four-barrel carb, it was the highest performance 327 available with a hydraulic roller cam.

What is a 350 with a 327 crank?

350 and 327s share the same 4.000″ bore… 350’s had a 3.48″ stroke, while the 327’s had a 3.25″ stroke. The blocks are basically the same, it’s the rotating assembly that makes the difference. With proper pistons, you could use your 350 crank and have a 350.

How high can a 327 rev?

The bottom end of a stock 327 can be safely spun up to 6500 RPM if it is in good shape. A stock 327 with power pack heads and a stock cam will run out of breath above 5000 RPM. The power pack heads have small valves (1.72 intake &1. 50 exhaust), and a stock cam is designed to make power below 4500 RPM.

Is a 327 crank in a 350 crank the same?

Will 327 rods work in a 350?

What is the difference between a Ford 350 and a 350?

The greatest difference between the two small-block, muscle motors occurred lower in the rev range, where the longer-stroke 350 offered an additional 27 lb-ft of torque. Given otherwise identical combinations, the 350 might be a tad quicker and offer improved drivability thanks to the extra torque that accompanies increased displacement.

What kind of motor is in a Chevy 327?

In the case of the smaller 327, the L79 was essentially a solid-lifter L76 (365-hp 327) with a cam swap. These two mouse motors shared the small-chamber, big-valve (fuelie) heads and aluminum high-rise intake.
