I pulled the car outside and let it run for quite awhile working the throttle to help break in the cam. It only quit on me one time and I did need to use the gas to get it running again but it did stay running at idle, it idles around 600 to 800 RPM and has an awesome lope! I drove it down the block and back with no problems so it seems to be drivable. I'm for sure going to get it dyno tuned, this thing should be about 450HP, not sure what that will be at the rear wheels.
