with 110,000 mi. on my '96 2500, it has developed an intermittent knock/rap in the motor that begins at about 2250 rpms. It is loud! I bought this truck 10 yrs ago, and alway do LOFs every 3k at the dealer.
Instead of tearing apart this motor, I'm considering replacing this 8.0 with a SRT/10 motor. I've found several of them available on the internet.
Has anyone done this swap? Does it match up to my tranny? Do I replace the wiring harness? or do I trade the truck in?
Any comments on the knock/rap or motor upgrade would be appreciated.
