I was told that you can take a large journal 327 crank and do a direct replacement in a 350 block with no modifications like that has to be done with some 383s any way 327s are a rare find and I have looked for a original block and no luck so I was told that I could make one I was wanting to know if any one has done this and if this is true I have heard alot of good things about a 327 I am to young to know from expierince.
Thanks

 

yes a large journal 327 crank would work just fine in a 350 block

Like ede said, it works fine. The name for this motor is .... (drum roll) .... 327. That's exactly what the factory did, although there weren't many of them; the 350 replaced the 327, for good reason.

We all quit building 327s back in the days when they were current, the instant the 350 started becoming readily available. 350 costs the same, makes more power. There's no advantage that I can think of to the 327 nowadays. It's not a bad motor or anything, the 350 is just better.

Since the 327 and 350 blocks are the same casting, all you have to come up with if you really want a 327 for some reason is the crank. Of course that's the hard thing to find because there never were very many large-journal 327s at all, because the 350 was a better motor. Nobody wanted 327s any more.

Let me clear this up real quick for you metallica.
The 327 is a very poor street engine. That's why it's history now.
You can spend the same money building a 383 and run over 3 seconds quicker E.T.'s in street trim.
The only way a 327 could keep up is by launching off the rev-limiter with slicks and shifting at close to 8000 RPM. Even then it might not keep up unless you have major money in the heads and a race chassis.

I agree, yet disagree. The 327 is a great engine, yet only for a light car. With our heavy cars, the 350 or 383 route is a better way to go, because they can build the torque better on the low end to get our heavy cars off the line.

I was refering more to the relationship between bore and stroke than cubes.

 

Forget about the cubes.
A short stroke engine N/A is a turd in a heavy vehicle. Most street cars are what I would call 'heavy'.
