hey everybody! first i would like to announce i just bought a mint condition 1988 Camaro with a 327 in it, the VIN sais it was only a base camaro with a V6 but thats ok cause it has a 327 now =D

and second i would like some insight on 327`s, how do they perform?, are they good engine`s? any input is helpfull, thx

 

A 327 is a 350 with a shorter stroke. They're good for running high RPMs since the short stroke doesn't stress the engine as much as a 350 would. Solid engines overall, assuming it was built/maintained right.

*Edit*
Congrats on the new car too.

 

A 327 is just a measurement of volume, how it performs depends a whole lot on whats on it. ie, "the 'ol 327 from pappys truuuuck over yonder", or "the 327 that just came back with the balanced rotating assembly with AFR's on top". My guess is it's closer to the first.

See if you can find out more details on that motor, from the previous owner. If he doesn't have a clue what's in it, then there's a 99.99% chance it's the first choice up there.

 

yea i`ll prolly do that tomorow

 

you have any facts to support that monkey spank? i always thought an engines ability to reach high RPMs had more to do with the engines ability to move air in and back out than the length of the stroke. considering the newest 327 is near 40 years old i'd pass on a 327 unless i need it to match a restoration.

 

its been completly restored, its runs like its brand new and everything is pretty much new on it

 

There's a sticky over on the Engine Swap forum about 327's. I haven't taken the time to edit out all the blather on it, but if you've got a good enough filter, you can get all of the basic usable information out of it.

About the only "bad" small block Chevys were the 262's. The 265's and 283's were just small. The 305 has breathing issues at higher levels of modification, but other than that, you can pretty much say that any SBC modification done to any SBC will produce predicatable and proportional results.

302, 327, and 350's all share a 4" bore. From 1962 to 1967 the 327 (and 302 in 1967) had small bearing journals. In 1968, which just happens to be the year the 350 was introduced, they all went to the large journals (although technically the 400 had the "large" main bearing journals, and the 302/327/350's had "medium" main bearing journals). Off-the-shelf, the performance aftermarket only really supports the large journal pieces. But, since your engine is fresh, that shouldn't be an issue for you.

You could say the 327 is a destroked 350, but it is probably more accurate to say the 350 is a 327 block with a longer stroke crank, since the 327 came first. A rebuilt .030" over 327 displaces 24 fewer cubic inches than a rebuilt .030" over 350, so at 1 hp per cubic inch, it will have about 24 fewer horses. Otherwise, forget all this talk about "high-winding" vs. "torquey" or whatever else you might hear about the 327 vs. 350, because what really defines a SBC's behavior are the cam, heads, valve train, and induction, not whether it has a 3.25" or 3.48" stroke. The peak torque and HP will be proportional to the displacement, all other things being equal. You could quibble about technical details regarding rod-to-stroke ratio, valve opening/closing, piston dwell at TDC/BDC, and that rot, but it ain't going to mean squat at the level you're going to be at.

 

Nothing wrong with a 327 if its put together right. Great for lighter car applications since the torque won't be as great as the bigger cubed cars. Had one in my 69 camaro and ran 11.80's all on motor. Now there were a lot of "good" parts on there but the 327 can be made to perform, and are a very reliable motor.

 

The 267 is just as bad if not worse. 3.50" bore x 3.48" stroke. Kerosene compatible compression. No head flow.

I've actually seen a 262 in a late 70s Malibu with Vortec 305 heads moving down the track. It wasn't too bad.
