CL77 305 Timing And Camshaft Position Question
So I'm rebuilding my 1968 305 CL77 engine and this has me stumped...
Lets start with timing.....
With the Rotor at F the camshaft mark is in the 6 o'clock position. Correct?
After 360 degree rotation of the rotor (returned on the F mark) the camshaft mark is at the 12 o'clock position and I need to hold the vise grips so the rotor doesn't turn. Is this correct?
....Onto valve-train/ lash....
I can only check my valve clearance on the T mark for cyl. 2 if the cam is in the correct position, the piston at TDC of course. If the camshaft is not in the correct position i need to roll the engine 180 degrees over and still piston #2 at TDC will allow valve lash to be measured.
Something seems a miss, hope you guys can help...
Thanks,
Chris
