I posted here just under a year ago about a complete rebuild of a 3.0 24v V6. I'll update the post soon as the engine is just about finished.
However, I spoke the engine builder today and he's timed my cams using the standard settings, and that's not what they need. They are a 'custom' piper regrind and need none standard timing. He called Piper before he fitted them and I think they though he was taking about the cam they offer on their website which is a drop in replacement.
So he needs to time them. He's a perfectly capable chap but not had much experience with these engines. He suggested I get some vernier pulleys. Now I know these aren't needed as the cam pulleys on the V6 don't have any key and just bolts to the taper, so in effect are infinitely variable.
His comment to me was 'However to achieve the other setting will require Vernier cam gears.
There is no way to turn the cams with thee standard gears removed.
So can anyone help me (and him) by explaining how you tune the cams without the pulleys on? I sure this must be able to be done somehow but have never done it so don't know exactly how!
I would be very grateful for any advice.
BTW - this is what the engine looks like at the moment
