4.36" Piston 514ci

Okay guys in the class I run I can not exceed 515ci, I have one long race every year of 300 miles. The jet drives are hard on engines as well as 300 miles of boat racing. I have talk with some people in the pump industry and they are going to make me what I need, what I think I need. Now to do this 4K rpm is my goal. I need the biggest crank I can not exceeding 515, so the 4.300"er is the choise. Pistons (4.360") for this are the problem, I have been told no-one has them as a stocking item anymore. I don't wanna have to have someone custom make them if they are sitting around somewhere.

Thanks
Jim

What about new seal power pistons you can get at the part stores for 200 to 300 bucks? They come in 4.360 bores.
