My block was cast first week of May, assembled last week of May. What month water pump casting date should I be looking for, May or June? My original fuel pump is dated 153rd day of 71 or June 2nd, could accessories be cast after the engine was assembled?
Removed my original in mid 90's and replaced with a Fluidampr for some reason, cannot find the LT1 balancer. 7173 looks identical to the correct 7712, not sure if it's a GM service replacement or factory issued in the late 60's? Thank you
First time seeing one in the 25+ years I've owned my 71 so I bought it. I've asked for a better picture but might have to wait until manifold arrives. It looks correct, not a '70 826 casting #. If a 330 manifold all I'll need is the LT1 smog tube to complete motor.
