Well, I guess I wasn't missing something easy. I took off the side cover, no luck. It is not the actual firewall, but at the top where the cowl curves out over the back of engine for the wiper galley. That is why they say to drill holes thru there. I suppose it just amazes me, that there is an engine compartment big enough for 2 small blocks, and you can't get the pushrods out of the motor. Hopefully I can loosen some things up, and move it ahead and down in the front enough to get them in. Thanks everyone for your help, very much appreciated.
