This fella just finshed installing his full cage and has it certified so now we are looking for some cooler temps then we hit the track.
I will print a graph and post it shortly.

Thanks for the props guys. The manifold manufacturer said we would gain 50-100hp. We've all heard that before 
but I was very pleasantly surprised when we were finished. I also went with an SD tune. The throttle body is a 105mm Accufab with no IAC provision so getting this thing started when cold takes some patience.
This car is a 100% drag car running race fuel. We are working diligently on weight reduction.
Erik: My car is finished finally running the exact same combo as before except 6 more cubic inches with the new RED block. I wish I had more time for the car but it just sits on the trailer
Someone will give it a good home.
I've been real busy guys. Hang with me, I'll get some photos and the dyno sheet posted as soon as I can.
BTW, I'm looking for a test mule for a new 450+CI LS7 race engine

As soon as I get the heads I can form an opinion. The GM heads are a real nice piece except for the less than stellar exhaust port but that doesn't bother me a bit.
