So here is another factor. We all agree and know a properly maintained 318 is mostly run into the ground. So if any of us were to break out the ol' Dialbore gauge on 10 or so 318's how many of them would even be in spec for a rering? And there in lies another problem. If you have to go through the rebuild process then why not just go for a 360? Same work just about and ahead of the game.
At the end of the day it's still 318 CI of a vacuum pump. In a perfect world for me I would love to actually put together a bone stock 318 in good running condition and do minimal upgrades to the motor and put some boost in it. I suspect 1.4 hp per CI can easily be obtained. But it will still come at a price tag.....
It's a good thread and worthy of discussion....
