Advice on compression in high elevation..
First off i am at 5400 ft elevation. I am building a forged 370, with ported 317 heads w prc .650 springs, with a D1 Procharger (pushing it hard). I will be getting a custom cam for the crappy air, running a ported stock tbody and ls6 intake. I will be running 91 octane (best around here on pump) with methenol injection. Also for a 95% street car what peak rpm should i have them spec the cam fo rand what compression should i have? i was thinking 6500 rpm(?) ...or 7000? 10.1 compression?. BTW its a 6M 2002 Trans AM. i am hoping to build 700-750 reliable rwh. thanks alot!

You will be able to run 10:1, its all in the tune.....
I have to ask though, what exactly are you trying to accomplish? Usually "pushing it hard" and "pump gas" are mutually exclusive...
You need methanol injection if you're going to lean on it with pump gas, and a GOOD tuner....
Who is doing the work on the car?
I'm up in cheyenne, if you need any help let me know.

For a tuner, you can give Servion a try. He is in the Springs at Revolutions and has a very good reputation for tuning cars in Colorado. Or, you can try Harvey at The Boost Creep. He also has a very good reputation. He is in longmont.
