Ok my brother is about to sell his 94 gt. He's going to let me swap some things out for cheap. I'm getting his lrs upper and lower rear control arms, ford racing aluminum driveline, basani x, under drive pulleys, fully ported upper and lower intake mani plus the gt40p heads and explorer intake that's sitting in his garage. Now for the questions. First with upper control arms I keep hearing stuff about the upper bushings to the torque boxes. They say to not run poly bushings? Any info on that is appreciated. The ported intake has a phenolic spacer in it and I was curious how tall of a spacer will clear the stock hood? Now how good is the explorer intake and is there any way I can get it to pass under California emissions? Thanks for your help guys!
