What do you think about this statement.........

8 bolts holding down 8 rockers or 5 bolts holding down a shaft and 8 rockers. I bet the engineers did their homework.

Consider how many valves are open at a time. The shaft bolts aren't really seeing any more load at any given time.
More frequently, yes, but total load, about the same.

Low friction rings? They are 1/16 inch rings. Nothing trick about that. I can buy off the shelf pistons with that ring pack.

The skirt coating is a joke. Waste of money but it’s done to make folks think it’s trick. It’s not.

Reusable gaskets? You can get them for anything.

When I get excited about 9:1 I’ll let you know. I’ve not measured one to know for sure but I doubt the vast majority are 9:1.

The heads aren’t better.

I get it. You can’t tune a carb because if you could you wouldn’t brag on EFI.

There is nothing “superior” about the magnum.

Magnums are low tension rings. Between that and EFI (reduced fuel wash) a Magnum pulls compression numbers at 300K that an LA motor stopped doing at 80k.

The Magnum heads are most certainly better flow wise. Cracking between valve seats...not so much. Define 'better'.

I've tuned literally thousands of multiple-carb engines. I'm an EFI man.

Lack of fuel wash, superior overall efficiency, self-tuning during all weather and altitudes, and spark control for every condition? But carbs are better because you can tune it with a screw driver and a huge box full of jets, needles, power valves, pump cams, and vacuum guages?
