Beginner's Bucks-Down /6 Build...Suggestions Welcome

I'm a little late to this party, but:

I have Fred Puhn's book. I'd recommend Herb Adams' book over it. Easier to read and understand, and his tuning approach is better suited to street cars rather than race cars. My first pass through it I wasn't impressed, the second time that I read it I liked it a whole lot better and it is now the book that I reach for when I need a reference.

If you want to dive deeper then Paul van Valkenburg's "Race Car Engineering & Mechanics" followed by Allan Staniforth's "Competition Car Suspension." If still deeper yet then it's time to bring out THE source, Miliken & Miliken's "Race Car Vehicle Dynamics", but if you do this be prepared for multi-variable calculus.
Somewhere between van Valkenburg and Miliken/Miliken fits Olley's "Chassis Design: Principles and Analysis." It's a tough read and I haven't finished it, yet.

I searched and got this, for a start...

There is a Fred Puhm book from 20+ years ago called "How to Make Your Car Handle". ....

snipped in the interest of brevity.

FWIW No professional auto trans rebuilder that I know (& would take my stuff to) uses B&M internal trans products. To a person they use TransGo products. So I've used TransGo products and never been unhappy with performance or trans life-span. If there is a correct way and an inexpensive way to do something in an auto trans you can count on B&M not doing it the correct way. That usually is to the long term detriment of the trans.
