Actually I think it will be a preety amazing engine, in fact IMHO it will take .12 performance to a level where we don't need it.
The 353 has a Tungsten balanced crank, ceramic bearings and the whole engine has the taste of a shrunk Plus 35.
All this costs money and now that NR started this §hit, all the other manufacturers will have to follow, which will let the prices sky rocket.
What really makes me mad though, is that they are trying to sell this engine in a package with a absolutely worthless and obsolete engine that has been thrown together using NR's leftovers from the last 5 years. Just look at the carb. This carb hasn't been on a NR engine for 3-4 years
