What goodies do I need to build a Fast slant 6

Flywheel HP. Jack Clifford is where I learned allot back then. His logo was 6=8.
As for the cam,it came from Clifford.Clifford was a good company before Jack Clifford died and his Son-in-law took over.Buying from them is iffy and many complaints now. I have no idea if they are even still in business.
There is a you tube video of the car making a pass.It's called Glenn Vs Romeo if you can find it.
I sent you the link to the Hot Rod article in one of the other forms where you asked.The cam spec is listed.
