Cranking motor from under the hood

[68_Step]

Is there an easy way to turn over a motor while under the hood? In the past I have used one of those remote starts that connect to the starter, but with this 67 C-10 that is a royal pain to attach. The starter solenoid is buried behind the frame and exhaust manifold, my hands just will not fin in there! Sure would be helpful for setting initial timing... Thanks in advance.
