difference between an L6 200 and 250

hello friend how can I tell the difference between an L6 200 and 250 I would appreciate any help, thanks

 

Easiest way is look at starter position. A 200 has a high mount, three bolt starter. The 250 starter is low, approx even with oil pan rail.

Fifth digit of VIN is T if 200, L 250.

 

250 has 4 bolt water pump...200 has 3 bolts. Late 200's have low mount starter same as the 250

 

That didn't happen until the '80s and are not directly interchangeable with the early 200.

 

thank you guys for your answers they helped me a lot
