I have a 660r top end that im going to bore. If interested i can go 666cc, 676cc, and 686cc. 9.9:1 and 11:1 compression options, 11:1 tack on 50. 300$ plus shipping gets it. Head is stock, can port out for additional cost and can include a cam stage 1 2 or 3 for extra 200. I live in Indiana so if close pickup can save

 

i was wondering what brand piston for the 11:1 compression you use and what brand cam you use

 

I use wiseco Pistons, and Hotcams. I can make up Bore kits for Raptors, 400exs, 300exs, and soon 450s
