I was thinking stock block, anything else goes.

EDIT: let me clarify, i do understand power bands and bob weight and what not. at least to a certain degree.




You understand bob weight. Now it's time for a little math.

2700 grams (roughly stock) spinning on a 3.75" stock stroke circle exerts about 11,400 lb/ft of force at 6000 rpm.

That same 2700 grams spinning at 8500 rpm exerts about 22,800 lbs of force. Going up 2500 rpm just DOUBLED the stress from the rotating mass.

Now, that's one hole. When all eight are spinning you can see that things are going to get ugly in a hurry.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
