Hey guys, thanks all for the replies, I guess I was kinda skirting the question knowing this is a restorers site,
The reason Im asking what I did, is because I want to run Merc heads on the blower engine Im building for my 34, Pete special ground the blower cam for me, and its big and nasty, without finding the specs, I think its 412 lift .
So, what I was wanting to know, is how much lift you can get under a 8cm head, will they take 412 lift ? Can I fly cut them to get the clearance ? or will they not even take that much cam ?
Am I making any since ?
Thanks again guys,
