1.6 rockers with this combo?

Against what cam?

Yes and yes

What is missing is the amount of overlap the cam has and what it is being compared to.

Well, Chevy, Ford or Dodge, an engine is an engine. With that said, outside of there basic engineering differences, generally speaking, there still V8 engines that work the same way.

Here is the key to a few things, what ever trick works on one may indeed work on another. What ever gains you power is the winner. Where ever you can find an edge, use it.

Some guys will pound their chest and say “I’ll only use mother MoPar parts! I’ll never use another brands part, screw that!”
This is IMO, a can be huge mistake. It also depends on the thickness of your wallet among other things.
Guess what I was trying to do was compare the same cam with or without 1.6 rockers, I thought maybe the 1.6 rockers might give me more midrange on that same cam vs 1.5?
Those were my thoughts as well engines are engines should work similarly.
Got chevy valves in the heads shhh.... lol. I am def. willing to use whatever is available to make the performance better.
