1984 Dodge W350 Crew Cab

[rekabeka]

OK, This is a serious question for all who have been there or would like to go! I have a 1984 Dodge W350 Crew Cab short bed that I purchased from the original owner. It has all of 60K miles since new. The truck is in very good condition with no rust or body damage. The problem is it is a "gasser" with the original 360 engine and non-synchro 4 speed transmission.
The question is do I convert it to a 12 valve Cummins w/ 5 speed or a highly tuned Cummins 4BT and 5 speed? Anyone estimate the cost of doing either? And lastly, who or where would I take it to have this conversion professionally done? Or, am I crazy for even considering this project?

Thanks, as always, for your input and thoughts!

Go for it! You're not crazy. Either plan would be a winner! I would even consider a common rail 4 or 6 and allison combo as cut out of a step van. example. I've never done it, but I believe the hardest part is replacing the front core support and getting the cooling package squared away. A rust free truck of that vintage is a tough find. If it's being done by a shop, please do your homework. You need a classic car or truck type outfit that is not looking for fast turnover. It's not going to be cheap.

I'm doing a 85 originally a gas 360 2 wd truck ,now Cummins 4x4

Both directions have their advantages. Both have disadvantages.

For simplest, go with the 4Bt as it is the same weight as a small block and then you dont have to get into suspension mods and frame boxing by the shocks. Also would do well unless you were heavily towing. Any smaller RV or car trailer would be good on a 4bt. Rear diff will also be reusable in this plan too vs swapping to a dana 70 or 80.

More importantly, where are the pics of this clean crew!?

The man above this post is the one to heed!

I can build a truck for you if you like just pm for details

The 4BT is not designed for passenger comfort. Bruiser installs them in jeeps and most of the people that have it done complain about terrible road manors. Go with a 6.7 and 6spd 2wd auto from same donor truck. The transfer case adaptor may be expensive but doable. A 6.7 with the emissions removed will provide ample power and longevity. Whatever direction you go sounds like a great truck when done. good luck.

The 4 bt is fine on the road worst case scenario you have to buy a fluid dampner is all , buy the engine you can afford and want and run it .
