I'm going for a three fer!!

"The distributor hold-downs are copper plated."
....Yes, your correct about the copper plated hold down. Mine is plated (What photo did you see that on my car??) Can you and were WHY it is plated???

The loose washer (found on many untouched cars) under the intake bolt (which have a captive washer) are brass or copper"
I'm sorry but I don't follow you on this one..

"The fuel pumps were painted on the engine."
Fuel pumps were painted??? Not on the T/As that I have seen, I might be wrong but here is another picture.... Many of the big blocks were painted but I don't know about the small blocks.
