Maybe they tried to roll them into place, that will get them for sure. Ive always used a ring expander and never had a problem. But tons of the old school guys still roll them in place, it can also tend to leave a twist in them if your not carefull. I'll go back and read this whole thread later, its a nice build for sure, what are the plans for it. All race like Pro Street, or a street strip type build? Interesting to see how a well preped ford will run, any predictions. All so sorry if these questions have already been answered, i just have not read through it yet. I'd like to catch up with you some time at a race and really look it over, nice job!
