My car and questions for a procharger

I've got a '69 Camaro, as you can see in my Sig. I want to get a procharger P-1SC with an intercooler for it. I'd like any comments and suggestions from you please.

I don't know what the compression is on the pistons, though. They were already in the engine and the guy I bought it from, bought it from someone else, and he didn't know what they were.

A real pain in my plans for sure.

Best quess though is high 9's to 10:1 compression.

So, I suppose I can just go easy on the boost and raise it til I can't safly run more? Or whatever you can suggest would be greatly appreciated. I drive it on the street whenever the weather is nice. And I'd like to take it to the track with race gas and push more boost to see what I can run.

Engine horsepower right now is 450'ish.

Thanks a lot in advance!
