I congratulate THEM as well. Must be Briggs & Straton engines. One mows and weedeats one side of the ladder while the other does the other side. Hard working and fast team. Great final and all fans were on their feet. It was fun, thanks to all that came.

I have a hemi question:
How does the weight and length of the rocker arms in the hemi engines affect rpm potential? Does it have any significant downfalls that causes major stress on the valvetrain?

I was thinking some of the engine guys on here would have answered your good question by now. Cat got their fingers or writers block! So from the Village Idiot of Hemi: The long rocker arm is on the exhaust side its not near the issue it would be if it was on the intake side. The exhaust rocker is aided in closing by the out going exhaust gasses. In a way, it has some help so the mass of the rocker on the exhaust side is not really an issue at all on the Hemi engines. It posses no problem what so ever to increasing the RPM range of the engine. Some Bob Glidden Pro Stock Ford Hemi engines turned well over 9500rpm with a similar length and far heavier weight rocker arm. We also have springs now days that handle much more than what we throw at them. The number one problem to increasing engine speed with a Super Stock Hemi is area. More precisely, valve area and port area. These engines are limited to a stock valve size and you can only fit so much air past a certain size valve. That should bring them out!!!!!!

Its all a big compromise. The lighter the rocker, the less valve spring needed to keep the valvetrain stable at high rpm. In the same respect, the straighter the pushrod, the less lift required to open the valve an equal amount (tangents). The rocker weight could be overcome with more spring pressure, but there is no real cure for bad geometry. I would say for 11k rpm,keep the pushrods as straight as you can and thats unfortunately the rocker length you end up with. If you can alter the fulcrum point, keep a mild ratio. It sounds like you need a DOHC Hemi! And where is Charlie?
