Re: It's running, how do I get to the exhaust shop?

You are going to need a good tune since the cam isnt stock. I would suggest finding a way to trailer it to the exhaust shop, get the exhaust done, then let it run a bit. Although 4k rpm sounds awful high, so like the other guy said, sounds like a vacuum leak, and a big one such as the fitting for the brake booster not being hooked up. Have you checked everything over real good to make sure you didnt miss anything?
