You know the predecessor to the Caddy North star was actually torquier and the northstar just winds up better, as to be expected with a 32v V8. I think I would look for that motor first as it would probably be better for a truck. Test drive a 90 seville vs a 92 and see what you think. The Northstar has the starter motor under the intake manifold and would probably be 'unpleasant' to service.
