castings

Anonymous-0 · Oct 16, 2013

I finally found a UB.The engine is stuck,before I did a teardown,I researched the casting numbers.
The blocks are 10A10248. These are 336 or 504 diesel blocks?? The heads are GE30Z. Are the diesel blocks interchangeable with the gas blocks?At first I thought I had G blocks as there is a spacer under the blocks.Anybody know what I have here compression wise or cubic inch?
Thanks

Not sure about bore, but, u can use diesel jugs on gas. A z head is same as a4210. The spacer is common when putting 336 parts on 283 crankcase.
