wildeyfarms Posted November 30, 2013 Share Posted November 30, 2013 I have a 1949 EQT that has a gas engine. I would like to switch it over to a diesel and was wondering if anyone knew what other models would make good swap material. the trans is a five speed duplex which I would like to keep. Any info or recommendations would be great. Quote 1949 EQT Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/ Share on other sites More sharing options...
2stacksuperdog Posted November 30, 2013 Share Posted November 30, 2013 Ive heard of putting 4bt cummins or 5.9s in them. Oh maybe a 6.9 or 7.3 international in there Quote Matt Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/#findComment-219112 Share on other sites More sharing options...
Superdog Posted November 30, 2013 Share Posted November 30, 2013 DT466 IH would be a good reliable and fairly cheap swap. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/#findComment-219124 Share on other sites More sharing options...
vision386 Posted November 30, 2013 Share Posted November 30, 2013 I agree with Superdog,IH DT-466 is a good dependable engine (and plentiful) any place that has salvage schoolbuses should have several........................................Mark Quote Mack Truck literate.

steve s. Posted November 30, 2013 Share Posted November 30, 2013 The 5.9 Cummins is a nice little engine from 160 hp up. I've just gathered up everything needed to install one into a 51 Brockway, replacing the big flathead six gasser. It looks like it will be a pretty simple swap. I have for sale a running DT466 still in a truck, which I could not use, as it is too long to fit under the hood of the Brockway. The Dt 466 is 210 hp and up. both are very good engines, easy on fuel, and easy to get parts for.

countryboy5487 Posted November 30, 2013 Share Posted November 30, 2013 I agree the cummins would be a good swap but everybody else has the same idea for putting the 4&6 bt's into everything. The 466 would be a excellent transplant if you have the room for one. Simple reliable and cheap. If you don't have the room for a 466 the 6.9 or 7.3 idi engines would be good options as 2stack said Quote Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/#findComment-219242 Share on other sites More sharing options...
wildeyfarms Posted December 2, 2013 Author Share Posted December 2, 2013 Thanks for your comments guys. I was originally thinking I could go with the 5.9 cummins, but I've stumbled on another early 50's Mack tractor on a nearby farm. It has a diesel in it that I'm sure would need a rebuild and I was wondering if anyone knew about the interchangability between different models and years. I'd hate to talk the guy out of the truck only to find out I couldn't use the engine. Sorry I should have been more specific in my original post.

2stacksuperdog Posted December 2, 2013 Share Posted December 2, 2013 Where are you located and what kind of truck is it? Quote Matt Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/#findComment-219483 Share on other sites More sharing options...
Gmerrill0516 Posted December 2, 2013 Share Posted December 2, 2013 I'm sure if you can give some additional details someone here can tell you for sure. What is the donor truck model and do you know what is in it for an engine? I think a bunch of this stuff interchanged but I'm not the expert on such things just yet.Greg Quote Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/#findComment-219485 Share on other sites More sharing options...
Vladislav Posted December 2, 2013 Share Posted December 2, 2013 Look over the plans you want to use the truck for.If you need it just to go to shows there's a reason to keep it with the original engine.Gas cost some $$ but you'll save alot on a swap.There are less and less original gassers and it's a point to think on my mind.Vlad.

wildeyfarms Posted December 3, 2013 Author Share Posted December 3, 2013 Vlad has a darn good point. I'm sure that most trucks get the gassers pulled in favor of a diesel. The reason I considering the swap is because I was hoping to show the truck as well as have it haul tractors to the shows as well. I don't have any specs on the other tractor yet. The guy who has it is not sure he wants to part with it and I didn't get too long to look at it. I'll have to get some more info and get back to you guys. Thanks for all the support. By the way, I'm near Cincinnati Ohio. 1 Quote 1949 EQT Link to comment https://www.bigmacktrucks.com/topic/33685-swaping-a-diesel-into-my-49-eqt/#findComment-219666 Share on other sites More sharing options...
Vladislav Posted December 7, 2013 Share Posted December 7, 2013 One of the Macks I have is the original 707 gasser.It runs but needs attention.If it had been dieselized I just wouldn't buy it.
