spec data

have you ever found that with high lift cams when setting them they are correct out the box and need no adjustment from the pulleys ?

Not one single time unfortunately. There are so many variables that are outside the cam manufacturers control that this would be very unlikely. Aspects such as the deck height of the block and how many times the head has been surfaced just as two examples will affect the relationship between the cam centre line and the crankshaft.

Thanks Andre Am having a real hard job trying to get the dial probe onto the bucket of my rb26 head, there is just no free space i will have to make some tool up have you had the same issue before what would be a good work around? and with all your experience whats the smallest adjustment you have had to make with regards to the degree on the cam pulley of an engine reason i ask is because on the opening event the probe was staying in the same place which correctly gave me 48 before bbdc at 1mm with 4 degrees of cam adjustment but on the way back up closing the valve the probe was moving and sliding across the bucket giving a false reading and giving me 14 btdc which was ment to be tdc at 1mm so the probe sliding all over the bucket was giving the 14 degree error might be useful for anyone else not seeing the correct data expected
