In contrast to a response above, the TH-2004R will fit any GM V-6 or V-8 that you would normally find in any of these cars, they were manufactured with BOTH the Chevy And B-O-P-Caddy bellhousing bolt patterns.

Given enough time and information I have enough books here to figure out exactly what you have and where it came from.

If the engine is original:
If it is a straight 6, it would be a 4.1 liter 250, dog but reliable.

If it is a V-6 it is NOT the original engine, the V-6's didn't appear until the:
200 Chevy for 78 and 79
229 Chevy for 80 through 84
262 Chevy from 85 on
OR the...
231 Buick from 78 to 84

The Chevy V-6's will have the ID numbers stamped on the block in front of the passenger side head just like the V-8's.

The Buick V-6 will have the ID numbers stamped on the drivers side of the bellhousing flange facing the drivers side of the car, between the lowest bellhousing bolt and dowel pin locations.

The Chevy V-6 has the distributor in the rear like the V-8, the Buick V-6 has the distributor in the front like the Buick V-8's, the L-6 has the distributor located on the passenger side of the engine below the #2 spark plug area.

The Chevy V-6 engines look almost exactly like one another.

Hopefully this info helps out.
