    It's all BS anyway. Not like anyone even cares. Just toss an aftermarket 70mm on it or swap to carb....

    Prolly a typo, but I can't edit it anyway.

      They basically just swapped some cylinders from a compression stroke to an exhaust stoke. Not sure why, but I guess it makes more HP some how.

        The lopo runs smoother, but is harder on the bearings. The HO takes the stress off the mains, but isn't as smooth. That's why all lopo's have that knock.

          The 302 lopo firing order is the same as the small block Chevrolet (actual cylinder firing order, not numerically). The 351/302HO firing order (1-3-7-2-6-5-4-8 on the Ford, 1-8-7-2-6-5-4-3 on the LS1) was adopted by GM for the LS1 because its just simply a better firing order; much more even force distribution along the crankshaft which GREATLY reduces bearing wear and results in a longer lasting engine that will stand up to a lot more abuse.

              Scream, Not bearings...It's a knock. Scream is prolly the transmission. Friggin annoying AOD noise.

                It also happens when in park if we rev it sometimes screams/squeals but it seems like it happens more when driving if we step on it to "pass" somebody it also screams ...VERY EMBARRASSING.....so new tranny?

                  if that's the problem...could be a few different things, belts, accessory bearings....My tranny in my old sedan sounded like a supercharger, everyone though the car was supercharged. Everyone was so surprised to see that it was N/A while I was sitting in the staging lanes...

                      All depends on the parts and your skill. The HO conversion was way cheaper for me, but the explorer makes much more power.

                      In a CFI case, a explorer motor or a complete HO with a carb would be the best route.

                        If I do just swap how much modifacation work wiil be needed to hook it up to my factory trans ? & will my wiring & stuff work ?? I'll be puting on a shift kit & changing the gear ratio But first I want to get the motor up to my specs. I have taken a motor out before but I have never installed. Its pretty much the same as removal just in reverse I assume. I have very little knowledge but I am a fast learner. I do know a lot more than someone who has never poped there hood. But I am definately still a novice. So I am just gessing but the Explorer is my best bet. What yrears of Explorers should I be looking for?

                          Any with the 5.0, 96-99 or so IIRC. Look through this forum for the carb swap threads. Intake, carb, lokar TV cable, need to decide on fuel pump setup, etc. All the info is in a few threads. The install is pretty much reverse of removal. Pretty simple.

                            can i just use the HO cams injectors and computer on my 86? cuz word on the street is that the mass air intake requires some different wiring. also, what heads can i use, u only mentioned 87 and up? or if i do choose to use the intake that u mentioned ( is that the mass air?) u only mentioned 87 and up for that too!

                              The intake is the same mass air or not. It's the pipe going to the intake that changes, and there is some minor wiring changes. For the HO stuff, go for the 87-up 5.0L heads, from a mustang or truck. 86 panthers are the same as 87-up. So all the mods are the same.
