The SBC has a tapped hole on the front of the block right down at the fuel pump boss, you install a bolt that's too long just snug to press and hold the fuel pump rod in place, once you have it in place and all the bolts started you pull that bolt (don't forget or you'll score the pump rod) and install a real short one that won't reach the fuel pump rod, then finish drawing up the fuel pump.

Be sure and put some silicon on that short bolt under side to keep it from leaking oil
