Contacting Jarod would be a great idea as he has a wealth of knowledge on the subject.
Also, I'm not sure an ABA block would be the best for a high reving motor. It is a tall block and therefore has a longer rod length I believe. This is good for torque but not so much for revs. I know the FI guys like it because of the forged crank and oil squirters but that is something you might want to research.
I'll keep answering your questions to the best of my abilities. You're not bothering me at all. That's why we're here, to learn from one another.
