Reprofile cams quiz..

[350ep70gr]

HI guys

I have 3 set of cams wich one set of them is reprofile. I want to sell this set to a friend who is coming right now..so i went to my store and dig them up.
The problem is all 3 set was together in the same box and i dont know wich set is the repofile one.
Also i mesure the lobes and all 3 set are different so i dont find two sets at about equal (oem) so the remain one is reprofile.
I have an engine lying around but i am a bit lazy to time it 3 times to find out..
Any other faster ways..as my friend is on the way..

Thanks in advance

Chris

probably a bit late now chris but if you use a digital vernier caliper you can measure the lift. this will give you some idea of which pair is which.

1st measure the cam across the journal as such to get a base measurement.
then at this reading lock it off and zero the meter.
then measure the journal across the lobe this will give you a ruff idea of the overall lift.

from memory that how i did it last time. lift is the easyest to measure duration requires more specialist equipment.

stock 4efte lift is

in 7.2
ex 7.2

5efhe lift is

in 8.0mm
ex 7.3mm
