Induce stress? not really. Are we taking some overall strength away? We have to be.... obviously the more material there is the stronger it will be.... but especially for a motor like this that will not really be making a ton of power, it's not an issue.

Reason you want a race block is because 1st & foremost they have very thick cyl walls... so we're not affecting that.

2nd reason, very thick decks, again no affect to that...

3rd fully filled in pan rails & main webbing. We just kiss the inside of pan rails a bit....

4th Race blocks, much higher nickle content block, if you ever hone a factory block & then hone an R3, will see drastic difference.

5th true 4 bolt main cap capability & again not affecting that at all.

6th, 48 degree lifter bore bank angle.... not affected.

We're just taking all the crap off these blocks that does not need to be there.... extra head bolt bosses, magnum motor mounts, Magnum crank sensor boss, fully filled in lifter valley, 59* lifter bosses etc.
