Look at my cam degree results

SBC hydraulic roller. Valve events at .050 listed on cam card:

IO 8 BTDC
IC 40 ABDC
EO 48 BBDC
EC 0 ATDC

As found:
IO 7 BTDC
IC 46 ABDC
EO 47 BBDC
EC 6 ATDC

Another thing, This is suppose to be a 228/228 duration at .050 cam. It measures 233 on both the intake and exhaust. What is the deal with that?

Specs on cam is 228/228 at .050 280/280 at .006 110LSA 4 advance. install intake lobe to 106 centerline.

7+180+46=233 intake
47+180+6=233 exhaust

Also done the Intake centerline method and got 109 which tells me I need to advance the cam 3 to put it at 106

I am very confident I have found true TDC. I am using a fixture that fits in the lifter bore with indicator that reads directly off the lobe for the degreeing process.
