What is the difference between a 327 and 350?

What is 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.

Are 327 engines good?

The 327 is a great engine and that’s why people are still talking about them, so was the 302, but there is a reason they were replaced. The 350 is every bit as nice as a 327 (if not even better).

What is a 350 with a 327 crank?

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. They have different main bearing sizes or somthing like that so it would be easiest to find an old 327 block and crank rather that trying to fit a 327 crank into a 350 block .

How many cubic inches is a 327 bored 60 over?

A 30 over 327 is 331.6; 60 over is 336.6.

How much HP can I get out of a 350?

a typical 350 Chevy can make upwards of 350 – 375 HP before you exceed the reliability of the components. For a big block with the same stock components it can make in the area of about 400 to 475 or so HP and handle upwards of about 500 HP before you exceed the reliability of the stock cast pistons.

What’s better flat top or dome pistons?

A flat-top piston allows the flame front to disperse evenly along the piston head, whereas putting a dome atop the piston interrupts even flame front travel. So, all else being equal, the dome itself is almost guaranteed to cost you some power just because the mixture doesn’t burn as evenly or as quickly as it could.

Do you need new Pistons after boring?

If you over bore the cylinder, you must use a new piston. More than likely, if the cylinder is worn out, it’s usually due to the combination of the piston and rings which caused it. The cylinder gives back as well as it takes, so these parts are worn out as well in most cases. New pistons are a given.
