My engine is a 1966 389cu in. that has been bored and honed .030 over.
Stock 1965 #77 heads. Harland Sharp 1.5 roller rockers, heavy duty springs.
Felpro #8518 gaskets in the car currently.
They are Flat top pistons. Was told they are zero(flush with deck. Not sure
Carbs are tuned with cam in mind. Car does run real good
Was told by previous owner compression is near 11:1. I have no way to know for sure.
All this is above my paygrade. I am NOT a mechanic. I can take anything apart and put back together, but I do not know what makes the internals of an engine perform perfectly.
Thanks guys for your time
