Well, I'm afraid you're listening to the wrong people. If you keep the 904, your shift linkages and column will work the same as now (a 360 is a small block, same as 318, with the same exterior dimensions as a 318). The kickdown linkage and throttle cable attachment brackets will have to be changed to 4bbl stuff...and ,yes ,its all available. A 340 throttle bracket will solve your throttle cable problems, and a 4bbl kickdown adapter (rod lengthener) will fix the K/D stuff. Do some searching here and Google to find the parts...they are available.
