Mine made 520-440 hds-up heads(54.8cc), gm bowtie blk, stk crank, 2-ring miller pistons, stk cam bore. Really nothing special ran .6 tenths under '64 chevelle in k. I think a good one makes around 550 hp. Larry Wilson 3058

I take it you are talking about Super Stock motors with a 4gc carb. Back in the day when my 283 520 head 4gc carb made 500 plus hp .95 under with todays indexs. 292 when you take bore and stroke = 1.71 hp per cubic inch, it would mean the 327 should make 560+ hp but there are lot of other factors into it also.

There were three incarnations of a 327 250 hp engine.The first was in '62-64,it had the 520/896 heads, the.398-398 lift cam, a 4 jet or a WCFB,and a skinny plenum intake.
The third version was in '65.Same short block,cam,carb and intake,but with 461 heads.
The third version was in '68.It is a large journal motor,has a .390/410 lift cam,#290 heads, and is about 9:1 compression, has an iron QJ intake with a Quadrajet.It came only in Chevelles, big Chevies,Impalas, wagons, etc,and pickup trucks.They were more common years ago, some of us still run them.They are pretty user friendly.
