Just a suggestion,

I'm assuming you installed arp or aftermarket rod bolts. If not IMO you need to invest a few $$$ into some good rod bolts!! Would hate to see yout throw away a lot of $$$ because or a rod bolt. You will need to get the rods resized after installing aftermarket rod bolts. All of the FE's I have built in the past had aftermarket rod bolts, it is mandatory on any performance engine.

For some detailed FE information you may want to visit www.fordfe.com They will lead you in the right direction.

Good Luck
