Mike: not sure yet. something i don't have to worry about number matching or if i do something to the car it will hurt the valve of the car.
Years ago I got a 62 QB engine from my neighbor so I went out looking for a car to put it in, around 1990ish. I found a really nice 64 Impala SS, actually bought it from an elderly retired school teacher (female) She bought it brand new and had every single receipt for every single thing ever done to the car. I mean every single one. The carb, alternator, starter had never been replaced but they had been rebuilt a couple times at the dealer. The pcv was cleaned like clock work at the dealer. Every vacuum line was original etc. It was a 327/auto with air. Yellow black interior. She even made it a point to tell me that the 4 hubcaps were the original ones that came with it when purchased, she was proud that they were never stolen. She use to take them off the car when parked in the driveway. I was driving it for a couple of weeks and as I started looking the car over I realized how friggin original this car was and decided that I couldn't do the engine swap as planned, just to nice and original. So I put it up for sale. I had bought it for $3500 and listed it for $5000, which was high at that time. This was back in the auto trader magazine days-no internet. So a fellow calls me and wants to make certain it's an original yellow car, not a repaint. I gave him the cowl tag info. Exactly what he wanted, he absolutely had to have an orignal yellow car
He was from out of state. He drives out to look at it and make certain. He liked it and drove to his parents about 100 miles away to get the money and then drove back and bought it, keep in mind my $5000 price was on the high side. So that original car went down the road.
I ended up buying a 62 Impala 6 cyl 3 speed that became a 409 4 speed car
Moral of this story
Nothing other then just felt like telling the story.
