1995 e7 427 engine search

[Jameco]

This is my first time asking a question in a forum so bear with me. 

I have a 1995 ch613 gold dog with an e7 427, from the research I have done I'm assuming it is a vmac-1. It has 1.5mil on the clock and has developed a good water leak out of the rear head gasket, I've been around the truck for years before owning it and I know it has had "iron tight" in it at least once before. 

So that leads me to beginning a search for a different engine, my question is can I swap my fuel system onto a newer e7 engine or do I have to stay in the pre '97 year range. I'm located in Oregon and am trying to find something on this side of the Rockies. 

I do all my own wrenching I'm just new to macks and they aren't very common in my area. Any help is appreciated

You have to stick to an E7, you cannot use an ETech "E7".  However if you had all the right components plus the know how, there's no reason you couldn't transplant a running ETech engine into the truck... But I wouldn't.  

What failed, the head gasket?  If that's all, then I'd just be pulling that head and replacing gasket.  Better to stick with an engine you know is good (albeit with a lot of use) than trade for one you don't know...

150000 miles! I would try do the head gasket! I have seen these go 30000 plus hours ! Check the block for crack’s if it’s ok  do the head gasket just my opinion!
