351 engine is for sure an E4OD it only got the E4OD or the C6.
302 engine is probably and E4OD they were supposed to swap from AOD in 1990.
There is a tag right behind where the shifter attaches to the trans on the driver's side.
The above pic sure looks like an AOD
Look for the massive casting rings around the outside of the trans. in this pic compared to the above pic.
