No.
yes just get head gaskets for the 350 not the 327
Yes they will.
Most people think that they gain more power from putting a 327 head on a 350. unless you get a head that is a high performance head you are not changing much.
yes
Yes.
327 heads do not have the mounting holes like a 350. Alt, and a/c brackets although if you are not using serpetine pully's they have no problem going on a 350 I have a set on my 350 and it runs absolutely beautifully
A 350 block with a 327 crank is called a 327. Bore it 60 over and it becomes a 337. Don't know what pop up heads are. Never heard of that.
yes it will
The age old question. Both engines are capable of producing amazing power. The 350 because it has a few more cubic inches should be able to be built for more power and the 350 also has more power fixes than the 327 just because it has been around more and there are more of them. For instance a 400 crank in a 350 makes it into a 383 which can be built to produce more power than either the 327 or the 350. But Chevy purists (and I am one of them ) prefer the 327 just because it was truly the first really impressive small block Chevy. The 265 and 283 were nice but the 327 was truly a mighty mouse.
327
a 350 or 327 that is the question. A 350 or a 327
not really......you can have the 350 heads reworked for better performance. Besides, the 327 heads do not have the mounting holes for the alt. and other stuff that mounts to the front of the heads I tryed this on a race motor I built. The heads were just too small. ANSWER You can go to after market ex: Dart or whatever u want, have the cc you want for compression, valve size that u want ex: 202 intake, ported and polished. You will get top performance this way. Match the heads to the engine.
