dx1075 Posted July 12, 2021 Share Posted July 12, 2021 Hey everyone New member here So i have been wanting an international 4700/4900 crewcab to make it into a pickup truck since i discover those things existed. Research shows people complain those thing are very slow. My idea was to find one with a blown motor and swap the engine for something like Cummins BigCam 3 or even better a Mack E6 Or E7 with a T2070 or TRTXL1070B and a supper tall rear end like 2.47 or 2.28 Would something like that work? Or is it just another stupid ideas of mine? I only need this to tow my 20ft landscape trailer on flat land everyday.

alex g Posted July 12, 2021 Share Posted July 12, 2021 Welcome aboard. Sounds like quite a project you are thinking about. Not sure how fast you are planning on going but instead of changing complete driveline you'll get same result changing rear end. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67319-international-4-series-crew-cab/#findComment-476702 Share on other sites More sharing options...
67RModel Posted July 12, 2021 Share Posted July 12, 2021 I don't even know where to start with this one. Running on 11R22.5 rubber with a 2.28 rear end and a T2070 you would be turning 678 rpms at 60mph and 791 rpm at 70 mph in 7th gear😂. A 4700 or 4900 series poop spreader chassis is not designed to fit a 12 or 15 liter engine under the hood so serious modifications would have to be done plus the front suspension would need beefed up....A DT 466 is only 7.6 liter by comparison. Plus I doubt either of the two larger engines' radiators would fit under the hood. I don't know you so I would never pass judgement, but in this case I will say it is just another stupid idea of yours 😅. Just change the rear end gear in the truck you buy. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67319-international-4-series-crew-cab/#findComment-476704 Share on other sites More sharing options...
Rob Posted July 12, 2021 Share Posted July 12, 2021 Anywhere over/above 220hp and those trucks perform well with a DT-466 engine. They also do pretty well on economy too. 1 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

dx1075 Posted July 12, 2021 Author Share Posted July 12, 2021 Ohh. Okay. I was hopping i can do 85MPH. And probably going with 235/80R22.5 Or 425/60R22.5 that way i can go with 4 wheels instead of six. The reason I was thinking the BigCam 3 is because on the series 8, like 8200 thise come with N14 belive the only difference is 2"-5" lift. But it will be something like thishttps://youtu.be/GwTKzIHkEcQ Quote Link to comment https://www.bigmacktrucks.com/topic/67319-international-4-series-crew-cab/#findComment-476710 Share on other sites More sharing options...

Do you think it will run ok with direct drive Spicer Or 9 speed fuller 2.79 rear ratio with 11R22.5 that gets 90 at 2k rpm Like i said everything here is completely flat.

Rob Posted July 13, 2021 Share Posted July 13, 2021 I can't comment on a 90MPH road speed as it is asking/begging for problems and someone, or something to get hurt. 75MPH in a medium duty chassis on smooth interstate is plenty fast and easily attainable. The 1999 4900 Lo-Pro truck I purchased new was 240hp, Spicer 6+1 trans and I cannot remember the rear ratio. It would run about 77MPH fully loaded with four cars on the bed and stinger consistently on flat pavement. The truck was comfortable too with rear air suspension and air driver's seat. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Wish i have cough this sooner. 22.5 tires from respectable manufacturers are rated for 75MPH max. Other sizes are only rated for 65MPH.
