Having trounble Degreeing new cam

cam is a lunati voodoo vdls-277

cam card reads

lobe separation 113

109 centerline

with 4 advanced

Intake opens at 4.5

Now when i measure the lifter a .050 i get 0.5

and when i use the centerline method i get 118


Can anyone tell me if this sounds right or if i need adjustable gears?

What timing set are you currently using?

How are you setting TDC on the wheel?

Can you post a picture of the cam card?

Stock timing set with c5r chain

I'm lining up the dots on the gears then puting the piston stop in and rotating it fowards and back getting it to true top dead

Im 98% sure im doing it right. Seems to me like i need to advance it 4 degrees just not sure

If the advance is not ground into the cam then you need to install it on a 109 to have those events.

You can get an adjustable gear set, or you can get a bushing kit and lock plate, you already have a nice chain, so the bushing kit will save you some money. You will need a drill press though to modify the cam gear.

Select the appropriate bushing and use trial and error until you get the ICL to match what the cam card specifies along with matching the other noted valve events on the card, IVO, IVC - default to the specific opening and closing event should there be a discrepancy - some lobes do not allow accurate degreeing with the ICL method.

i bought a rollmaster adjustable gear set and advanced it 4 degrees now the IVO and IVC are spot on but the ICL is now at 113 should i advanced it another 4 to get it to 109 or leave it?

Most of the time unless you tell the cam grinder that you will be degreeing the cam and you will not use it if it is not perfectly spot on they will let it out the door as much as 2-6* off.

Believe me, we've seen plenty of them like that here at our shop.

Leave it - like I said, use the IVO and IVC numbers if there is a discrepancy.
