What would be the drawbacks or pitfalls of this combo? What size carb and cams would work best.

I have the +3 crank and a set of Web cams now and am considering the bigbore cylinder.

What exhaust works best with these bigbore motors?

I would say your connecting rod would take some serious abuse due to the crank angle and the extra forces put on the rod from the bigger bore. It would last a while though,given it is properly built, and jetted.
