Very Nice!
What water pump and timing cover did you use?
Looks like '68 style pump but in aluminum? and a maybe a later style cover (if I'm seeing the timing marks on the left?)
I remember playing around with the front cover in order to get the pumps discharge to work with the radiator I could get. Also had to take care of the harmonic balancer so timing could be set. I also recall that the change to the Sanden compressor entered into the decision making process. It allowed me to eliminate the A/C idler pulley. (The alternator lets me apply tension to the belts.)
