**sfi Approved Damper**

That's cool. I was just simply asking, not talking bad about anything...I really admire this build because I REALLY want to build a stock stroke 318 screamer!!! I know about the 408, I have a touch over 11 grand in mine! I don't know where all the money goes! Might have been those damn Eddy heads! I should have used the complete Indy Head top end package!
