I am curious as to wether they have taken all that metal pinch out of the 5 and 7 port break in wise on the GX's. I know that this was something being thrown around. I will say that when I just about a month and a half ago when I broke my gen 5.5 3 port in that bump box breaking pinch wasnt there. I heated it up to about 160 and it started right up. It only got stuck up top 1 time. But that is the 3 port I know they have always been easier than the 5 and 7 to break. They may have done this on the 5.5's I just didnt hear anything about it. I know I want a GX 5 port and I think I will run this 1 stock. I have never had a race mill stock and want to show that they dont need modded. I may have Rex do that thing that he was talking about that takes away the bottum end punch if I need to I will run it out of the box 1st.
