Have a 307q motor in a early 73 express cruiser. Trying to adjust valves and need to turn the motor by hand to accomplish this task. Any help would be great. Using a flywheel tool that only turns a fraction via the feet takes way to long. Is there a way to use a ratchet and socket assembly?

Don't the Q motors have hydraulic valves?

My operator's manual does say they are hydraulic valves and don't need adjustment.

yes, they do, but I was told by the machine shop that replaced the valves to set it at zero lash and in order to do this correctly I have to turn the motor (cold lash).

Robert,

The easiest way is to buy a remote starter switch, you can get a cheap one at places like Harbor Freight or any auto parts store. Chevy motors with hydraulic lifters should be set at zero lash plus 1/2 turn. best way to determine zero lash is by turning the push rod as you tighten the rocker nut, as zero approaches turning the push rod will become more difficult. Dont worry about adjusting in order, just start with all loose, and keep adjusting until all rockers have no play. 

I always used to adjust while running method both for the 327f solid and the replacement 350 long blocks with the recon heads.

I did read something about that last night. If I recall, you can do half the valves in one position and the other half in a second position.

It's about halfway down on this page:

Remote Starter Button is the best method. You can bump the engine in fractions once you are close.

I did barr mine over when I bought it, used a pulley holder from NAPA that kinda-sorta wedged into the exposed bottom of the flywheel.  PITA, kept mashing my knuckles, no easy way to reach it.  No batteries for using the starter.  Soaked the cylinders with PB Blaster then fogging oil first.  Ended up blasting the straw into one cylinder, and having to turn the motor to get that piston to the top, so I could fish it out with picks.  Winter in Sturgeon Bay, no heat, good times! 

I was actually happy, both engines turned over normally after decades of sitting.  Tags on the engines were dated and initialled for many years of checking coolant and apparently turning the engines, but I wasn't convinced 'till they actually turned over.  Nobody really knew their condition, it was a gamble.

If you make or find something that wedges into the flywheel, that will work, best if all the spark plugs are out.

Thank you Dan, based on your post, I ordered one the other day
