Truck 383 Different than car 383?

Hi guys and gals, I have an opportunity to buy a 383/727 out of a Dodge truck. From the various reading I've done on FABO I've learned that there is a difference between the 5.7 Hemi found in trucks, and those found in cars. Did the same apply to 383's back in the day, or are the car/truck 383's identical?

From what I've found online so far, it sounds like the car/truck 383's are the same, but I wanted to confirm with the FABO crew.
