Hey there, so I know my pinto has had the motor and tranny changed and I never really cared until I started looking for parts. I can say that it’s a v6 with a 5speed other than that I couldn’t tell you. When I got a thermostat gasket for a 79 v6 it looked nothing like what I needed. If anyone knows any numbers stamped somewhere without having to rip it apart that would be awesome.

Thanks a bunch

What it is....   Well the Pintos had a 2.8L V6 - assuming your car is a '79 that might of been the original engine.  Assuming the engine is a cologne V6 (2.6, 2.8i, U.S. 2.8, 4.0)  The bellhousing for these engines is the same.  That's the good part...  The bad part is the "cologne V6" engine blocks have a partial bellhousing casting extend rearward so that it requires a very long transmission input shaft {or an adapter).   So if the trans is actually a 5 spd (there were none original for a cologne V6 in the US - other than the Sierra & trucks I'm pretty sure....) the question is what the trans is...  Might be a Ranger trans, a Sierra, possible a T5 (with an adapter to move the input shaft pilot bearing past the crank).  You need to pull the trans off to see how many splines on the input shaft and the clutch diameter.  The Mustang II clutches are getting hard to find the last I checked (these are 8-1/2" dia).  I have found places to rebuild them.  You need to measure the clutch disc.  If you have a T5 with a pilot bearing adapter, check this carefully - my first spun in the crank.  My cologne V6 uses a Mustang II bellhousing with 8-1/2" clutch and an early fox body V8 mustang T5.  Ratios are great.  The truck 5spds are too low in the first gear ratio & I don't think these fit without floor mods.  Good luck!
