is there someone who knows the maximum lift we can have without valves to pistons clearance. The reason i ask is that i bought the crane stage 4 and the tech at crane said maybe i will have problems maybe not so i`m lost. If so i will buy some cam gears and turn off the vct.thank guys for your help

 

Wish I could help you, but I have no clue. Try posting at modularfords.com too....

 

ok thanks i will try

 

If the guys at Crane can't help you than I would return them to the source you purchased them from or throw them in a lake. If Crane did their engineering work properly then they should be able to tell you specfically what the install issues may be.

well your right but the guy said it is race cams and they did`t test it on a stock block so the test car has aftermarket pistons but i agree that sucks they can`t tell me.
