Re: Compression Ratio question
Sorry , all is stock HO engine , crank , rods , pistons , cam , lifters , rockers.
I want only (I have only) GT40 heads "F3ZE" casting and GT40 intake with 65mm throttle body but I need higher compression than stock engine.
Maybe in the future I buy high lift rocker arms.
How much I can downground heads for high compression ??? 0.04" is maximum for "closed intake valve to deck clearance"
BTW: this GT40 heads have 68 ccm combustion chambers ???
