What's up guys? My question starts off as what do you guys think is better? I have an '88 5.0 with just about all the bolt ons. Electric fan, aluminum flywheel and driveshaft, 3.73 gears, CAI, 75mm MAF, 75mm Throttle body and EGR spacer, 24 lbs injectors, A9L computer, GT40P heads. And now I just got a hold of a GT40 tubular upper and lower. It came with a 1 inch phenolic spacer. I also have a 3/8 inch spacer from my old intake I was running which was the explorer upper and lower. Both spacers will work as I compared the 2. Which spacer should I use with the new GT40 intake? I know because of the bigger phenolic spacer, it would make sence that I would get more torque out of my car because I'm basically increasing the length in the intake runners. So what does everyone think?
