Another novice question: I understand GMC went to the 403 when they stopped production on the 455 big block. I have both on my potential buy list. I know the bore and stroke and torque figures are very different between these two engines but is one considered preferable over the other in the 26' GMC motorhome application? I note that many have changed their rear ends from 3.07 to 3.70 so let me stipulate that change in my question. Maybe this is a Ford-Chevy issue with personal preference being the definitive factor? I guess I am asking if one pulls a hill better than the other and if the higher revving small block is noisier or more prone to early death. Thanks.
