The 3500 Express built '95-'03 was supposed to be powered by 502 Gas.,Cats 435. cummins 6BTA 370 and cummins 6 CTA 420/450. The way the engine room was made, it had room for the large diesels. My question still is if cummins had a 407 horse power engine for the 3500. A 3500 exp. is being listed for sale with 407 hp. cummins.
