Anyone interested in some 4140 main caps for a 360?

I always thought it was the cylinders that were the weak point on the LA blocks, not the caps? From what I have "read" it seems cylinders crack which is the more serious issue over some cap walk??

Im just wondering how much the caps would make a difference is all. I just did a little over a half fill on my 360, running stock bolts and caps...hopefully it holds up to 700hp at the crank LOL
