I had my motor built by IPP with 400+ cams I purchased from a locsl member here. Issue is that I have an issue getting the timeing belt to act properly. The intake cam lobes make contact on the edges of the lifters instead of the center like normal. What this is doing is making a sudden tension everytime the intake valves need to open, its so much tension that the timing belt will skip teeth (even with the right tension). This is all on an engine stand and the motor has never been run, just wondering if this has happened to anyone else?
