If you use HD intake manifold gaskets with the blocking plates over the EGR ports, you won't have any exhaust flow to the EGR and you can delete it.
The red block was first-year. no improvements. The paint color was only that and lasted until EARLY-1983 Also, That was the ONLY year the engine had the Most Nickel in the block and Coarse Thread injectors. If it came from a 3/4 or 1-ton model it probably had the DB2829-4153 HD Pump which is actually quite good Otherwise a 4090YL LD. Other small things like the oil cooler lines from the Block side were only used 82-83? 3/8" I think. NPT Fittings vs Newer YR was more of a "Quick Disconnect", and the "Thread-in" Glow plug controller was used 1982-83 The 2ndary Fuel filter on the back of the Intake was the same. 1984-87 It was just Flush (Deleted).Makes since I was just going off numbers said 81 in casting numbers so assumed 81. Where there improvements on the red block or is it as simple as just paint color? Thanks also ill let you know if I take egr off but it's pretty ruff looking and hasn't been hooked up in years motor actually was in a fruit tree spray rig before I acquired it.
The 6.2 will tow just as much as a 454, if not a little bit more. a few of the guys on my 6.2 group on Facebook i have seen towing up to 15,000 lbs of round bales and the eng grunted a little bit but not much.Nice lots of good info I like it. Hopefully it treats me well I will only be doing light towing and cruising around as long as I can at some point get this over revving issue figured out. Thamks again
Glad you got the issue resolved.Just incase anyone is interested I was able to get what ever was stuck in injector pump unstuck and I have it idling. No clue what was stuck but I filled fuel filter with seafoam and cranked tell it was coming out of injectors and then let it sit for a day and periodically tapped on the pump. Bled it out and fired it up this morning ran great. Thanks to everyone giving me some knowledge
