Some look stock, but have internally been "smoothed up" Maybe have to take it off and look at it. I had one that looked stock but was smoothed up, it was a long time ago that I bought it, so I don't recall the place or name. The RJC plate is specific to different upper plenums. Look at his web-site. The pictures show quite a difference in design from plenum to plenum.

How about this pic in through the TB... Does it appear to be smoothed out? Sort of does to me.

This motor work was done about 7 - 8 years ago in Amarillo, TX. I have actually talked to the guy who owned the car and had the work done to it. He is a dentist with a passion for speedy cars. He can remember quite a bit of stuff that was done, butI have not been able to get every mod done. He did not spare much when going through it. I know the heads and intake were sent to Champion.

Sorry to hijack your thread, but I have been told by a few that the PP is a good investment, but also that there is better places to spend money at. If I could find one for a good deal, then it would not matter too much...
