The whole system is a restriction. How much you open it up is the key for power. OK, duh! We knew that. The real trick is to apply the available power effectively for the task at hand. Since the engine is limited due to OE parts, next in line would be the drive train and vehicle weight.
Get creative fellas, get creative!
@Woodie What is the goal of the car?
Did you/he have a cam in mind?
Why a .842 lobe? IDK ether. The can get pretty aggressive but a Ford mutter is larger than a Chevy and a Mopar lifted is larger than a Fords and then there is a mushroom tappet (if you can actually find one) and then a 1 inch lifter size.
To actually take full advantage of a .904 lifter, you would have to build a pretty hairy engine to match.
If I had to put a rpm band on the stock intake, it would be 6K max rpm (but i’d push it more to 6500) until you start porting it.
