i am moving over from my acquisition thread to individual topics. I’m finally out of trunk and under hood to access what I’ve got here. I already know the block is a correct 70 Z28 casting but cast about 5 months after my car assembled so not original. Maybe warranty block, but not known at this time. The pad is clean. The carb is correct for 69 Z28/L78 and I will sell or trade that for rebuildable core. Carb looks wet which concerns me. Intake is clearly a Winters but off what? Where is casting number? I know the casting date is underneath and can’t be seen when installed. And that blue plug in front of intake on drivers side? The distributor unfortunately has electronics hidden under cap. I saw the date and was happy with Jan 30 1970 but then saw last 4 digits and 2002 is not the correct distributor. Anyone know what that came out of originally? I am looking forward to yanking the vintage air. What is that solenoid looking device on pass side of intake along top of valve cover? Part of AC system? Any help would be appreciated.
