I put the extra scavenging pump on there to pull a little vacuum on the crankcase. Just trying to give the rings a little break. Should be around 1000 hp on 10 lbs but we will see I haven't put it on the dyno on the new setup. The old 427 made 897 on 6.5 lbs. Just going for a bad ass street car. I have a 15" wheels for when I need some real traction. On kill I will get whatever the little turbos will do.
