Today, dollar for dollar, is the 318 faster than the 340 ???
The problem I have with this thread is the built in bias of the basic comparison. A running 318 compared to a non running 340. The running motor has to win out.
For this comparison to be fair both motors should be freshened up. Then you make your comparison.
In other words the question should be, Can you make a 318 faster than a 340 for the $1500 you paid for the 340 core?
I think the answer is still yes, but at least now the comparison is fair.
