best 330 kit?

[monster300]

i was wondering what the best 330 kit is, and do all big bore kits require racing fuel?

I had purchased a 330 kit from Powroll, it was a huge improvement, but make sure that you get someone to do the work that is reliable. There is no oversized piston that I could find when mine blew up because the shop that installed it had it jetted too lean. I was then forced to either buy a new 330 kit but I opted for the Pro Fab ATV 385 kit. This one will be done by PGR Racing, the guy is a genious. You will have to run race gas, its based on your compression ratio. I would suggest Pro Fab: Powroll didn't offer any help when I was trying to figure out why my engine blew.
