Rotary to a P-pump?

[9 Lives]

For my convertion I have been collecting parts. Several engines I have found were 1st gen. 12 valves. Can the older style injection pump be switched to a p-pump ? What all is involved if so?

Yes, it can be switched. You need a P pump style front cover, the pump and injection lines. There may be a few other pieces Im missing, but it can be done.
