Hey steponmebbbboom, you want to continue to correct me on the term "cranking." Maybe you have a definition for cranking or starting or whatever you call it that is technically correct. Your help is appreciated,
Yup, and 440_Magnum's definition of the roots of that term as i know it should set you straight on it and why it confuses some of us. let me fill you in on the other terms i used and what they mean:
BTW, thanks.

You call it "on-the-rock" which is a term I have never heard,
this means that as you wiggle the crank back and forth, both intake and exhaust rockers will rock back and forth, and where they are both at roughly the same height, you are at TDC which is useful in adjusting your valves in the following way, a valve adjustment method seldom described but easy to do:
the firing order for your engine is 1-5-3-6-2-4. If you stack the first three on top of the second three like this,
153
___
624
this will show you which cylinders are at TDC at the same time. 1 and 6, 5 and 2, 3 and 4. Wanna breeze-through a valve adjustment? Turn the engine over with all spark plugs removed IN DIRECTION OF NORMAL ROTATION (CW on the crank pulley end) until a cylinder, any cylinder, is "on-the-rock". Now make that diagram of
153
___
624
and find that cylinder on the list. The number vertically aligned with it on the other side of the underscore is at the perfect point for adjustment. Adjust intake and exhaust to spec, then roll-over to the next cylinder in firing order and set the cylinder opposite to "on-the-rock". this trick works with any evenly-numbered engine, including a V16 detroit. No more futzing around with rotor position and timing marks, just bar the engine over and watch the rockers. Factory-approved method for many engine MFRs.

You say I "need to be on TDC compression stroke for the cylinder you are adjusting so both intake and exhaust are at base circle
base circle? see this diagram:
if you are anywhere close to TDC on compression you will definitely be on base circle that is why my valve adjustment method works even if you dont watch the timing mark. with intake and exhaust cam lobes at different positions it isnt quite 110 degrees, but you have plenty of wiggle-room.

If you knew me, you really would know how much of a perfectionist I am, and that I can really drive you crazy until I accomplish what I strive to do. And I will do so even if I ask questions you may think simple.
Dont thump your knife and fork on the table and no one gets hurt, thats what brought me here in the first place.
