I took the valve cover off, I think it was leaking anyway.

I have to say, this is a 360 in a 79 D150 half ton. A small block in a truck.

AND THE F-N VALVE COVER ALMOST DIDN'T CLEAR THE BRAKE BOOSTER.

A small block in a truck, not a Hemi in an A-body.

Sheeesh.

Can barely reach the distributor, need scaffolding to stand on.
