If you do the math, it comes out to 379. It even says that on the website, 4mm crank, 1mm piston, add that to the b x s, you get 379, 7mm crank, and 1mm piston, adds up to 396. I dont want a +4 crank, I wanna +7 But, I dont see how it would be worth it to put $1500 into a 350!?!?! Makes no sence what so ever! IMO. I should just get a 450 or 700 Raptor. They look cooler, and are faster. Then, I dont have to worry about there not being any parts out there.
