Hi people,
I have a 77 L82 and am thinking about fitting a set of Edlebrock Performer RPM heads.
Correct me if Im wrong, my standard heads are 76cc with a standard compression of 9.5:1 (or is it 9.0:1)
The heads I will be looking to fit are 64cc.
Any ideas on how much the comp ratio will raise with the 12cc difference?
Your engine uses the same camshaft (L46) 350/350. i I think the pistons are the same as the 350/300 engine. Your heads will increase it to about 10.00:1. I have the Edel RPM 64cc heads and the same flat-top pistons as the L-82 as well as the aforementioned cam. Others will correct me if i'm wrong.
