Can you stroke a small journal 327?

Stroking a small journal 327 block with a 400 crank is slightly more involved than stroking it with a 350 crank as above. There are 2 ways to go with the turning of the mains on a 400 crank. I’m not terribly crazy about the first method, but it will work fine.

Will a 327 crank fit a 350?

No can do. As 47chevycoupe stated, the extra stroke length will put the pistons about 0.23 inch higher, or way above the deck. 327 stroke = 3.250, 350 = 3.480. Your 68 327 should be a large journal, but it might be small journal.

How do you tell the difference between a 327 and 350?

Measure the stroke. If the stroke is 3.25 its a 307 or 327. If its 3.48 its a 350.

When did Chevy stop making the 327?

Are 327 and 350 blocks the same?

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.

Which is better 2 bolt or 4 bolt main?

Any time you increase horsepower, torque and cylinder pressure, you increase crankshaft load. It would take quite a bit more stress to rip-out 4 bolts than it would just 2, so that’s why the 4 bolt mains are stronger than the 2 bolt mains.

What is the difference between a 2 bolt and 4 bolt main?

Two bolt means each main cap uses two bolts to hold it down. Four bolt means there are four, which means more clamping force, and less likelyhood that the crank is going to push itself out of the bottom of the engine at high RPM / power.

What is a stroked 327?

A 327 stroker is just a 331 with a stock bore instead of a 30 over bore. The 30 over takes it to a 331 (actually it would be a 332, but who’s counting…). The 327 is most likely assembled from a new block instead of a rebuilt block.

Can you stroke a 327 Chevy engine?

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.
