I'm just going to set this out for everyone's benefit:

The 6.2L and 6.5L diesels were developed *solely* by Detroit Diesel. Izuzu had nothing to do with them.

Specs on the 6.2L:
Introduced 1982, normally aspirated, indirect injection, 2-V OHV, cast iron block and head.
Compression: 21.5:1
HP: 143 hp @ 3,600 rpm [107 kW]
Torque: 257 ft-lb @ 2,000 rpm [348 N*m]
Weight without accessories (J-code): 655 lbs. [297 kg]


Can anyone find specs for the 603.97? The mythical 603 that revs to over 7,200 rpm? And only masses 100 kg?

the 603, i believe runs over 500 # and has power similar to the 6.2. less torque i believe. max rpm 4000 something. there was a post with mb engine weights recently....within the last year.
