Jerry how many people/cylinders would you need to make custom 500 cylinders in the 1000-1500 range?

I would have to do a cost analysis at today’s tooling and casting cost before any accurate numbers could be done.  At this point I would guess 300 to 400 cylinders.

I doubt if there are 1000 to 1500 LT 500 still running in the world.  Of these 1500 I doubt if 100 of the owners would spend the money to buy a new top end, pipe, carb, ignition/power valve controller and get the Quad's mechanical condition up to the point where it would take the increased power for a while.
