KB's in a 318 with No Re-balance

All this so you get 1-1.5 points of static compression? What's the actual power increase you expect to realize here? 10% on a 300ftlb engine is 30 pound feet of torque. And I'd bet the price of pistons and balancing that you don't realize 10% from that specific change. So this is worth risking taking out the block when (I don't feel this is an "if" situation) the pin augmentation works it's way out? Have you ever had the pin move and put a gouge in the bore? I've seen it on pressed and retained pins and I'm no pro doing it every day.
With all due respect you guys really amaze me. Never have I seen so much time taken to avoid spending on things that have such little effect on how an engine runs or lasts...lol.

LOL, I agree on the odd things that are thought about.

But I'll disagree over the value of the compression change.... It is not the peak torque gain just from the CR change... it is the ability to put in a larger cam without killing the low RPM torque and making a dog out of the engine for street use. The chronic 318 dilemma..... You increase the cam without killing the low end torque AND that will increase the peak torque and peak HP more than stated above. There is nothing new in this....

As for risk..... LOL. There are SO MANY ways to harm an engine. We all know that just flipping the rocker shafts upside down will kill the valvetrain in short order; we see engine mess-ups here every week or so. Now if you can identify a way in which these inserts will likely move and fail, then I am all ears. But just raising a 'strawman' failure without a good rationale.......
