Installed the 570 ES cams today , sdjusted acording to procedure with each cyl at TDC of compression stroke, did the 3.2 turns after finger tight on a 32 TPI GMR adjustable pudhrod kit, waited 15 min for bleeddown and it worked perfect can turn with finger no slack after each 15 minute period. Now after doing the each cyl individually I turned the engine via back tire, I check the rods again all spin except one after each revolution. Different one is tight each time. Does this sound right?

 

Could be possible as the duration / lap can be forcing a load on one of them. Do they all spin feely on TDC of each cycle of adjustment? The only way to know is adjusted on TDC for each one.

 

Yes they spin freely on the TDC cycle. but the ones taht are not TDC are tight.

 

That is the way she will work they are all invarious stages of the cycles. If you have adjusted them per the directions and on TDC all of them free up you should be ok.

 

Yep what he said!

 

The one not spinning freely is the one pushing the valve at the moment. If they are good at TDC you are good to go. No harm in starting over if you are unsure. Loosen them all up at TDC and take another shot at it.

 

Thanks gents I will crank the motor over today. hope it does not grenade.

 

Top Dead Center of the compression stroke the push rod is on the heel (base circle) of the cam. That's the point where they should rotate easily with your fingers. Anywhere else on the stroke & the push rod is either on the ramp or on the lobe of the cam & will be impossible to rotate. You would only be wrong if you *could* rotate all of them at the same time.
