mackmb212 Posted October 9, 2012 Author Share Posted October 9, 2012 Those first 350's were called a ENDT678 if I remember right,but shortly after renamed as a E6-350.First one I was around was in a '80 Cruiseliner demonstrator that our dealer was passing around to it's customers. Superdog would any of the Mack v8s fit under my hood and would it bolt to my quad box. I was told it can be done but I would have to use a bigger radiator.

Maddog13407 Posted October 9, 2012 Share Posted October 9, 2012 wow, im confused myself haha. tip turbin, intercooler, air to air, half water, half whatever wow. i know the early 711's had head gasket issues with the old copper gasket. some of the newer ones i have seen have the newer thin gasket and firerings the the 237's. my END707 had the thinner gaskets and the firerings on the deck. its a 1977 engine block in my b613. i know its an oddball engine and everytime u mention it someones says a 707 is a gas and i say, nope, its a diesel. runs different to, think the operating range is 11 or 1200 to 1800. you can run it yo 2100 but it doesnt shift as good.

Not a 237 because the cam is different. after I asked that question last night I found a thread asking if a 711 Jake brake would work on a 673 and the guys were saying the 2 valve engines used the same jake.

It can happen to any engine. Antfrezze will eat brgsand water is bad enough but antifrezze is a killer. Any time antifreeze has been in the oil it is good insurance to change the brgs. I always said to check them and if you check all you as well to go change them when they are down. glenn Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/27695-rebuild-or-replace-711-with-turbo/page/2/#findComment-143694 Share on other sites More sharing options...
