5.4L Iron Block
8.5:1 Compression
VT Stage II PI Heads
VT Stage II Blower Cams
Bullitt Intake with Adapter Plates
Single Blade Accufab Throttle Body
JLT CAI

Through a 5 speed.

What kind of power/track numbers do you think I'll see out of it before the blower? I'm a pretty good driver on the strip so I dont think I'll fair to bad. I'm hoping to see mid 12's out of it n/a at 2200 feet @ 80 degrees ambient temp - then I'll boost it.

What do you think ? Would you guys change anything ?

8.5:1 will lower your performance a good bit. Bump the compression to 9.5:1 and you'll be within spitting distance of your goal with a proper tune and you'll still be able to run plenty of boost without race gas.

The blower cams will really show their stripes once you toss the boost at it.

Define "plenty of boost" in reguards to the 9.5:1 ?

I thought that for big boost, lower CR was optimal. I'll be running 20PSI at a minimum.
