Inline 6 Block Casting Identification help

[Bigjam]

Have an old straight 6 in the bronco and looking to start doing a rebuild can anyone help with identifying the block based on this casting number?
8Z
D8BE
6015-GE (not 100% on the GE)
I think its a 250 but want to make sure? Any assistance is appreciated

If yr sure its not the larger 300 truck I6 then the 250 is the only other possiblity; the 170 and 200 were no longer in production in 1978, which is the baseline design year for that block.

Looks like a 75-80 could be a 200 or 250. Is it a small block V8 or I6 bell pattern. If I6 it's a 200 it V8 it's a 250.

Guessing 200 due to the GE.

Its an I6, was hoping I had the 300, but it does have 5 freeze plugs on the side if that helps?

Looks like it is the 200, I appreciate all the quick responses..., now nayone in dallas want to trade this 200 for a 300? LOL ;D

A 250ci will have 4 water pump bolts, 200ci 3 water pump bolts. A 240/300ci will have seperate head and intake, not cast together.

Saw that on their site. Wonder why my TRW engine parts guide shows the 200 no longer in production in '78?

The 200 was used thru 1983. Although it was renamed the 3.3 in the mid 70's.
