383 Stroker

[Ducaire]

Will someone compare the 327, 350, and the 383? I know that the 327 has a little more horsepower while the 350 has more torqe (forgive spelling). What about the 383? Does it have more horsepower and/or torque than both of the other 2 engines?

Didn't get enough answers from your other thread about the same subject? http://www.automotiveforums.com/vbul...d.php?t=376371

Your spellings fine.

If they're stock motors Everything about the 327, and 350 really depends upon what year your talking about.

All 327's are high compression, So were some 350's and they are the stock motors that you want. If they have never been re-built you might have to get the heads re-done with hardened valve seats.
GM started making low compression smogger motors for 71, and until the 80's some time. You should avoid these motors since they are lower power.... a little like buying a worn out motor right from the factory.

With the 383 then it depends how it was built. And some builders get more power out of their motors.

The 383 should have the most all around power unless it was built for racing. Then all the power will be close to red line..

However the 383 will also cost way more than the other 2 motors

You should probably look at Summit Racing motors http://www.summitracing.com/ and see what you want for your price range.

them talk to your local mechanic and see if he can build you one for less

When buying a 383, how can I tell if it was built right or not?

I would not buy it from the "average joe" but from a engine shop. I purchased a re-built 350 from an engine shop that was a business and they had an assembly line of motors that they were building. Along with a ton of engines sitting, re-built and ready to go.

Do some research of engine shops in your area. Or research a engine builder. Get references, phones numbers and talk to the past customers.

That is the only way to get a realiable engine.

OR ... buy it from someplace like Summit or Jegs. Usually, any place will give you some sort of warranty with the motor.

be carefull Even with an engine shop.

My mechanic builds race motors for fun, so I'd trust him. He's even made a mistake while building 1 motor before, so no one's perfect But he'd fix any mistakes

Find out who built it, and ask them for some referances. People that they built performance motors for.
Ask if they have built any for racers.

Then interview those people.

You'll be spending a lot of money on that engine, and you want the full performance potential, and you also want it to last.

Performance motors never last as long as a stock motor, so ask them how long they figure that it will last you

stock 350, make sure its a high compression year, if not, then go a head and redo it so it is high compression, its not as simple as that, but thats what needs to be done

a 327 head will bolt right on a 350 giving you high compression
