K trucks used straight dump. Any straight dump will work. I guess it's because the v8 engine sits in the rear position like a 6 cylinder engine is mounted closer to the firewall. The straight dump gives a bit more clearance for the down pipe of the exhaust. Especially for trucks with manual transmission linkage.
