Installing crank pulley
On the auto its a little more different. You can use a compression gauge adaptor, put not the gauge<, and apply compressed air, about 100 psi to one cylinder to hold the piston down in its bore. You can remove the pushrods to help seal the air pressure, but if you don't feel like doing the extra work when you apply the air pressure to the cylinder you may need an extra hand to help spin the motor over for the air pressure to seal. with the pushrods in it may just take half of a revolution or so to stop the piston on the compression stroke....This is what I did on my auto.....
