Re: 92 Bluebird, want to put in 290 cummins by Mike Beckham
Post New Message Hello Robert. I will give you my 2 cents worth on this subject. I am a factory trained Cummins mechanic with 14 years experience, but have left the mechanic side of it to drive 18 wheelers, due to a back injury. Many things come into play in a swap like this.These are the questions you need to answer before trying to do the swap. 1.) What do I hope to gain? ( more power, better mileage etc.) 2.) Will you present tranny and bellhousing bolt to the Cummins 290? ( probably not.) 3.)I am sure there is a huge weight difference between your 5.9 and the 290 Cummins,and factor in a differnt bellhousing and clutch, and maybe a big truck tranny, that weighs a 1000lbs by itself. you could easily add 2000lbs. to the front of your bus. 4.) A "skoolie" usually has a very low geared rear axle (5:13 to 6:17 is common). A 18 wheeler rear axle is anywhere from 2:90 to 4:10. The 290 Cummins is governed to 2100 RPM, with a 5:13 rear axle you would have (maybe) a 60 mph bus. IMHO a better choice would be a diesel from a medium sized truck like a ford 8000 dump truck, or as Phil suggested a DT466 International engine.The key is to get the whole truck as a donor if possible to use the tranny and maybe the rearend. The 290 swap can be done, but it would really be a challenge.I don't want to discourage you, but having done some wild swaps, you need to know what to look for. Good Luck, Mike.
