You should look into an intake manifold with a burst panel. Blower restraints are nice to have. I remember being at Orange County International Raceway in 1979 when an airborne blower killed a little girl. That was the incident that caused race gear manufactures to create blower restraints, and NHRA to enforce the use of them.
8.5:1 with 10% over is going to make some real horsepower. In the early 90's I was part owner in a funny car that was mostly run in an organization called the California Independent Funny Car Association (CIFCA), on a 7.50 index. We did crank it up a couple of times to try our hand at NHRA Division 7 Top Alcohol.
The car had a Keith Black block and crank, Bill Miller Engineering rods and pistons, Brad Anderson fat heads and intake manifold, Enderle roller cam valve train, Enderle fuel pump, Enderle fuel injector and hat, Mert Littlefield Hi-Helix magnesium blower, Mallory Magneto and ignition box, Crower 4-disc peddle clutch, and a Lenco air shifted 3-speed.
