Did my research. This wear, which is wear from the piston skirt, can apparently be caused by two things:


1) PTW Clearance is too tight

2) Bores are out of round (no torque plate)


If left untouched, this thing wouldn't have lasted very long..


Thank God I pulled the head.


Oh, and Christmas came a wee bit early:

I notice a little slap when she's cold, and after hearing my old motor with JEs I know the sound quite well .


I'm just going to run it and give it hell. If it fails we'll all know who was actually right, seeing as everything is built/being lubricated properly and I'll be at ~400whp for awhile.


Unfortunately I sold my 65mm to purchase the Full Blown so I won't really be doing any testing. However, you'll see by the graphs how everything is working .


If I don't crack 400whp on pump I'll shed a little tear.


And also, Chris, I apologize for being overly skeptical about this wear, however, seeing as I'm a broke college student that dropped ample money (to me) on a motor, I'm overly cautions about every aspect of my build, as I really don't have the budget to fix anything big at this point.


It's more or less common knowledge that .0035" is quite tight, especially for higher HP levels, but I'm trusting what you're saying in that the wear is normal and I'm going to run the motor.


Like I've said above, I only use the best oil, Wix Filters, my car doesn't leak a drop, my inline FP filter is always cleaned, I'm running a Kiggly HLA, and I've nearly crashed my car because I keep such a close eye on my Oil Pressure.


My new head is mint, I'm using a Cosworth Cosmetic HG, and I'll be keeping a very close eye on my compression and leak down numbers. 


Thus, if I notice something is up with the motor, we'll know about it and can easily rule out oil starvation/contamination, unless I get a bad batch of Brad Penn 10w30 or my oil pump fails.
