My question is which is best suited for a fast road/race engine. John
SI try the links don't seem to be working from photobucket for me
Hi John,
As Ian says we probably need a little more information about your engine and intentions plus more on the cams themselves. That said, from what you describe, the second cam with only a little (?) more inlet lift and standard exhaust is probably milder than any of PigSty's grinds?
A quick way to determine the lift of these short duration cams is to mic' across the maximum dimension on the nose of the cam and then repeat at ninety degrees to that. Take one from the other and ignoring tappet clearance - that's the cam lift. Did they come with followers as there's another decision to make there.
