I even admitted to that above. No sense reinventing the wheel, it rolls fine in its current shape. Same with a lot of builds. I doubt there isn’t much already covered, done, dynoed, track test & well enjoyed by many.
The only thing with the books is information becomes dated and the parts availability go away. The listed cams and etc…. Parts in the MP book are drying up and some are available via eBay or on line forums.l, but once MP stops ordering cams, you have to make an intelligent choice for its replacement. It’s not generally hard to do.
L Shepard has plenty to offer in his books on combo’s.
