1982 Bronco with Explorer Engine
Hey guys
I recently got a 1982 Bronco with a 5.0L. The motor needs to be replaced and I'm going to be putting in a GT40P Explorer motor in and have a few questions.
I know those heads need special headers. My question is does the list remain the same from the list that all the Mustang guys do or can different ones be used.
My next one is with the stock distributor. What gear should I use? I've read where people try to get one and its a different size than the stock one. The steel ones I try to find for the roller cam seem to be for MSDs.

No they don't you just need to make sure you DO NOT try to use equal length headers or any Mustang specific header... those will present frame and firewall interference issues in a truck. Any standard short or long tube header where the tubes go straight out a bit before curving will offer enough clearance for the plugs and boots.
You need a steel gear, best advice is remove the current one and measure the shaft diameter and then simply search for one that fits it.

Use the flywheel currently on the truck or a new replacement. I'd change the ATF but don't forget to drain the TC as well, should be a total of 12-14l of fluid. On the other hand dark fluid suggests the trans is worn and probably not far away from needing a rebuild itself so maybe don't bother until you get the truck running and can assess the overall health of the trans.

I've read that long tube headers for our trucks with 90 degree spark plug boot will work. I'm planing the same swap but i can't verify that.
As far a distributor goes most autoparts stores sell distributors for any year truck with a 302 with either steel or iron gears.

Not sure why you would be happy to take a significant step backwards in reliability, accuracy, and performance by using a distributor. The Explorer 5.0L engine is equipped with EDIS8 from the factory, I would swap the entire drivetrain into the Bronco including the EEC-V and harness that goes with it. Later on down the road, you can tune the EEC-V if needed.

As cool as that would be it is a much much bigger project.
