Hmmm... I've been told the 1098 engine fits the 848 mounts. For argument's sake, would the sf848 cams fit the 1098 heads? A more tractable 1098 with more power than the 848 would be the goal. NOT threadjacking, just conjecture and maybe a purchase of the presented engine if this is feasible.
Addendum: Also just noticed the seller is in my city!
