Nice looking setup Clair. No, I won't be using injectors, just an Edelbrock 600 cfm. My engine builder used the magnum M1 manifold hence my temptation to change over to the late model stuff. He used the early model timing cover so I could run a mechanical fuel pump.
It looks like a lot more work than I anticipated. Maybe I'll just adapt my old stuff to work or change the intake for one with a more centered water outlet. Thanks all.
