Of course this is my opinion, but is based upon many personal 9 and 10 sec passes. and building race cars for customers, I don't see any chance of you running mid-9's with your current build combination and just adding the cea 67 turbo?
Since HP needs air flow and RPM, you are limited on both to start. You say nothing about your heads, and even with maxed iron heads, they are not close to the needed air flow needed for mid-9's/140 MPH w/o crazy boost?
The SLIC is also another big restriction in air flow and cooling, and will not provide a decent air intake temp? With e-85 the combustion chamber temps will be lower, but you with be putting air in that would be close to 100 degrees hotter than a front mount.
Your dyno numbers seem really high as they do not equate to the track performance numbers? To pick up 1/2 a second or more, you will need about another 150+ HP to push your "brick" at 140+MPH?
You will also require 60's in the low 1.30's for the mid-9's, and your converter will not be capable to accomplish the higher launch boost needed.
If the cam will give you the higher RPM you need, it should be fine but may need more spring pressure.
HP gets expensive in the 9's, and the combination becomes more critical, good luck as I hope you do well!
