I realize you're trying to get by with not much lift but I don't think you will get there without putting the engine a little farther down and back more. If you want I can send you a dodge exhaust manifold so your mount issues are a little easier. I probably have a dodge oil drain too. The ford bus/F700 AC mount is probably the one you're talking about. They're pretty pricey. Auto world also makes mounting brackets and a dual pulley to put ac compressors on the head above the injection pump.

Thanks for the info. Most of the time I'll be towing 8000lbs on an open trailer and the most would be 15k on an open. Don't own an enclosed, at least yet That said, I don't want to have an issue if i get in traffic on a hot day. How many core is the 94 dodge stock rad? I could get an upgraded BBC 4 core. Currently there is a 3 core in there. I've got a 2nd gen intercooler for this, looks like it will fit well but I may have to cut the core support upright braces to not push the stock 86 grille out the nose too far.

Actually i'm within an inch (front to back) of where most of the mount kits for these trucks have the engine placed. If i move the engine down any more I'll definitely need to lift it since the axle will be too close to the oil pan. Is the fan the only reason you're saying go down and back? I can't go back without going down.

As for the dodge manifold, thank for the offer. I need to do more homework though since I feel that will create an issue of putting the turbo too close to AC/heater box if i go with stock chevy AC box for the evaporator? I need to see if thats a better option vs the Thermo King or Vintage air. uugggh many considerations.
