I had good luck installing the o-ring about halfway on the pickup side, slathering it in assembly lube and engine oil and then pulling the pickup on (I was working from the top side). You could feel it give when it went together. Should go by hand.. shouldn't need to tighten the bolt to pull it on

Agree.. .should go on by hand.. it was easy for me as I installed everything with the engine on a stand. As someone mentioned, the windage tray, and in turn the pickup get moved a little with spacers when using a stroker crank, but that is not an issue in itself.

Like I said in my earlier post that I've seen some factory motors that tight, but no one should be setting up a performance motor that tight. Like I said just make sure you let the car warm up well before doing anything other than slow normal driving. The AL. blocks will grow about one thou. when they get up to temp, but still relatively tighter than most performance motors would be setup normally. But it might be fine, just put some miles on it before trying to kill it for sure. GL! Oh And yes the tight clearances should help generate more oil pressure, but the AL. grow everywhere and bleed oil off. when hot IE: like the lifter bores etc...

Awesome! Glad to hear it was a (relatively) easy fix....
It's crazy that o-ring made that much difference. I understand why.. but still
