#15 455 heads on my 350
« on: November 14, 2009, 04:40:39 PM »
What compression ratio do I get if I have my #15 87cc heads bolted onto my 350 motor?
The motor currently has the #11 heads installed.
Inquiring minds want to know.

Wallace racing's compression calculator those no.15's on a 350 at 8.1-8.2:1- great for regular.

I knew there was a chart somewhere.
