First Time Degreeing Cam
Need some serious help here.
I bought a degree wheel kit from Summit and am attempting my first degreeing
Getting true TDC was easy enough after I made a piston stop. The heads are off and am now checking the cam. Here's where progress comes to a grinding halt.
First - do I really need a solid lifter for a hydraulic flat tapper cam? I don't have one. I read you can put the indicator needle on the top of the lifter as long as its not the cup.
Second - I can't get the indicator far enough down to reach the lifter without using a bad angle that does not represent the angle of lifter travel. Do I need to get an indicator extension or am I just an idiot?
Third - once I get issues one and two worked out, how do I set my readings for the indicator? Does it matter where the cam is positioned when I set the indicator?
Appreciate the help on this

on. You just need an extension.
Third - once I get issues one and two worked out, how do I set my readings for the indicator? Does it matter where the cam is positioned when I set the indicator?
Once you rotate the crank around to intake lift on #1 cylinder you'll see everything move.
On your cam you're looking to have the degree wheel read 6 degrees BTDC when the lifter is at .050 lift. That will be a 106 intake cneterline, then you're good to go.
