The thermostat is inside the intake manifold. The upper radiator hose connects to the thermostat housing (on the engine side,not the radiator). Remove the hose, then remove the two bolts holding the housing and there is your thermostat.
I believe that is 35 to 38 point dwell for a 1966 Ford Mustang 200 straight 6 cylinder
35 to 38 dwell at idle RPM for your 200 cubic inch straight 6 cylinder in a 1965 Ford Mustang
The .38 Special is a specific cartridge. In addition to the .38 Special, there are perhaps a dozen different .38 cartridges. Most of them are fairly obscure/ obsolete today, but include the shorter, fatter, less powerful .38 S&W, the .38 Long and Short Colts, the .38 rimfires, .38 Merwin & Hullbert, etc. Sort of like "What is the difference between a Ford Mustang and a Ford?"
On right side of engine, pass side , under air intake hose.
mine doesn't have plug wires but mines a 4.6. It has individual coils on the plugs.
Start with 4.5 qts. Top off until full and make note of the amount.
It is mounted to the lower intake manifold just below the thermostat housing. It has a connector with two wired connected to it.
Once you get through all of the available missions and content, there is no longer any aircrat too unlock, you can get a mustang, but not a P-38.
The P-38 was the Lightning, not the Mustang. There were at least 14 fighter versions plus two photo-recce and a night fighter.
Burnt valve, blown head gasket, bad plug wire.
38-- It was 1901
A wiring schematic for a ford 38 engine can be found through Ford related service manuals. The manuals depict the original factory placements of the harness and parts of the engine.
