Not sure if this should go here or in the 1st gen but this has more posts so...I have an 95 D100 Custom with the 727 transmission and the 2bbl 318. I tow with this rig and find it somewhat under powered, but not by that much, surprisingly. The one thing I despise is the 0cfm(160 cfm) 2bbl Holley carb. It is a hateful thing that I really feel restricts power and causes it to backfire when I dump off the gas on the highway. So I want to upgrade, and putting a new carb on is out of my price range as far as I can tell. My #1 choice simply because of installation ease is a 1st gen ram 360 4bbl, but they just aren't out there. However I can find a crap load of 2nd gen magnum engines. I know I will have to do a bit of wiring to get the ECU to work but what my question is; is will I be able to just drop a 2nd gen engine into a 1st gen truck? my main concerns are the bell housing fitting, the starter fitting, the specs of the output shaft being the same, and the mounts, though I could probably weld in some new mounts if I have to. I am also wondering if this would be the same if I picked up a Cummins 1st or 2nd gen. Appreciate the help.
