When did Chevy stop making the 327?

The last iteration of the 327 appeared in 1969 with a two-barrel carburetor and a 9-to-1 compression ratio that produced 235 horsepower and 325 foot pounds of torque, but by then another Chevrolet small-block had already appeared on the market and had begun stealing what thunder the 327 had left..

Will a 327 crank fit a 350?

The 327 crank will not fit into the 350 block unless it is the post 67 327 crank with the large bearing size. With this crank all you need to do is use regular 327 parts such as pistons. I would use the larger balancer off of a 350 though as it has better dampening qualitys than the 327 balancer.

How much horsepower does a 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.

How do you get the most horsepower out of a 327?

Re: What’s the most HP possible from a 327? ( Select a cam to yield the low end 80 percent torque bandwidth at no more than 2000-2200 RPM and spend to the limit of your budget on the heads, inlet, and exhaust system to get peak power.

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.

Is there a 327 4 bolt main?

No – GM never made a 4-bolt 327 for production use; many have been drilled and tapped for six extra splayed bolts with aftermarket main caps on the #2-3-4 journals by machine shops, but GM never made one.

Will 350 heads fit on a 327?

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.

What is the strongest Chevy engine?

6.2L LT5Our fastest crate engine ever As the power behind the 2019 Corvette ZR1, the new supercharged 6.2L LT5 represents the pinnacle of Chevrolet’s performance: It’s the most powerful engine ever offered in a Chevy production vehicle.

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.

What is the difference between a 283 and 327?

There is a “wing” looking thingy above the front cover that sticks out of the block. On a 283 you can’t lay your finger in the indentation, on a 327 you can. Hard to explain but easy to see if you know the difference.

What can you stroke a 327 to?

The 327 has a 4.00″ bore which is the same as a 350. You cans simply add a 350 (3.48″ stroke) crank to make a 350. For close to the same money, you can use a 400 (3.75″ stroke) crank which gives you a 383 with an .

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.

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.

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.

Can you stroke a 327 Chevy engine?

Yes you can. It has the same bore as a 350 so a 350 crank is easy but why not make it a 383 or 396 with a longer stroke. If you are replacing the crank and pistons go bigger.
