That would be nice...but for the cost of a model Conley V8 engine, well more than $5K USD, that is almost half of the cost of a crate LS7 crate engine!

I dont know how much the cost of the rest of a 4th scale Z06 would cost, but considering that a real '09 Z06 costs at least $75K USD, the 4th scale model better make up for the high price of the Conley by cheapness of the rest of the RC itself!
