I like your long term plan... haha just kidding
That's a great way to find out what you really want and/or need in a car and you bought in at a nice price from what I can tell. The Prism Red is a GM paint code that is posted on this forum somewhere so you can have it mixed and it should be close. That color has a huge following in Mid-America, I think 80% of all Prism Red cars sold were at GCPC.
Your engine was probably originally setup with a holley carb and that's where it dynoed at 460HP. I'd bet if you went back to that you'd have 60 or more HP then you have now the the Mass-Flo. We installed one of those systems and it was a battle and a half. We changed mucho parts and I think a custom tune to get it where we thought it should be.
Granted the Mass-Flo system today could be another animal, but I bet the one you have predates our experience.
Don't be afraid to bring it up. I can have that hood fixed and get you sorted if it does not work out in NJ. Our truck and trailer is down your way all the time and usually empty in one direction or the other.
