I have one of those installed in a 64 Chevelle 4 door. It had 64K on it when I bought from original owner. My wife wrecked it with 72K on it. It is parked in the barn.
Had a few of them over the years. They had chrome, dipstick, air cleaner, fuel line, vacuum line valve cover and the PG cars had a chrome stick on them also.
Didn't they also have different timing curves in the distributor? I have a few of them partially tore down and the one described above is fully intact. It really did run well. We drove it on vacations and would usually see about 19 MPG.
Every 64 Chevelle with a 230 had this Hi PO 230. Well everyone I have seen thru the years.
