I have all the usual mopar books but all the set ups they advise are antiquated cams if 1.6 rockers would be a better set up the so be it.
Antiquated? Hummmm, the grinds maybe old but they still work. So, IMO, antiquated doesn’t quite fit. Old? Yes.
But what the book is showing you now is the parts used to do the job but you’ll have to make modern part choices. Here is a good few examples.
MP says to figure can duration @ .050 it is the advertised duration multiplied by .850. Your choice of a more modern cam now has a lead in duration to look for.
I’d advise in what ever duration you use, get as much lift as the head can handle. I’d look at 108 C lines. On most of the MP cams, I’d run the 1.6 to quicken the action on the rocker/valve opening rate. It’s not always needed. It’s not a must. Lift has a direct impact on HP, if your head support the addition lift.
Example #2;
MP suggested to use there 6 pack intake set up for best results in those bracket tips there to perform in. There is one big problem with that idea, that’s expense.
A RPM-AG is what you would substitute and a carb to fit.
You have to remember that the 6 pack was the best and ultimate dual plane intake manifold ever available.
Even when they suggested to use there single plane, I’d still take a hard look at the dual plane and double check the cars weight. If the car was very light, it would be the single plane.
