Hi I have demounted my engine to change the cam and head's.. but I do not find the cc on my old heads. I have check the listing I know on the net but the only info I see is what year they where prodused well if anyone can help me the casting number is: 458642

A quick google search turned up this:

"these are 76cc chamber, small valve crack prone smogger heads that are lighter than the 882 units, they make good wheel chocks or boat anchors."

hi
Thanks.. I didn't do a google,,,
sometimes the easy is the best...

now, I just demounted the heads. Now have to find some info about tha pistons. Anyway to find the Piston Head Volume?
I did belive this was stamped in the piston.
The thing is that I plan on going to put on 64cc heads, but I have to be sure about the clearance and comp!
Just for information, I did not know the comp.ratio in this enginge before I took it apart.
this is a 2 bolt block-engine that was in a -83 trans am, but I think tis is not the original engine.
