Can anyone tell me the stock cc's of the 1969 #47 heads. I have not been able to locate that info. Thanks, Pete

I believe they are 72CC.

Thaks David, I'll go with that. I'l have to check out that site more. I was just reading the post about 67-68 bird and "viola" you had replied to my post. Thanks for the quick help, Pete

My pleasure Pete

Pete,
The 47's that were on my 69 350 (late '68 casting dates) were 88 cc (I measured them myself.)

Hmmm. Very interesting. Since I don't know how to check the cc's I'll have to go with factory specs. Whats it take to check cc's, anyway Pete

Put your heads on a bench upside down and make sure the upper surface is level. Fill the the chamber with a liquid. The volumn that they hold is the cc's. 1/4 cup equals 60 cc's. Tablespoon equals 15 cc's. Teaspoon equals 5 cc's.

Pete,
What Jim said, except that I use a piece of plexiglass (with a small hole drilled in it) and seal it down to the head with a little grease (for a more accurate reading. Surface tension of the liquid will give you incorrect readings otherwise.) Then I used an animal syringe (available at farm supply stores) to fill the chamber.
