6.2 diesel rebuild

[80' 427]

So I have a 82 6.2 with 92k and the original engine. Currently with the hx35 turbo it makes 210 HP and 475 ftlbs. I am happy with the power but the blow by is bad enough to start pushing oil past seals. I know a CDR will help but knowing that it was beat like a rented mule in a former life I think it may be time for a overhaul. The more I think about it the more I think I should inspect it well before any machine work and if it tests good just do a stock overhaul with felpro gaskets and new head bolts. No studs or girdles. Am I crazy? I just think if it is crack free now more than likely it will remain that way. I could go to (insert other diesel engine) but right now I have this one and a spare and during the overhaul I will be adding a nv4500 or a ranger(I have both).

If . . .

If you're really worried you could put ARP studs in and maybe a girdle on the bottom.

Generally if an engine has been crack free it will stay that way, unless you get stupid with building power. A good rebuild with good quality parts will last a long time. Using head studs and a main stud girdle is just good insurance.

The power output you stated is a pretty substantial increase over the stock engine....probably around 50% increase in HP and almost double the torque. Not sure why you wouldn't at least put ARP studs in?

Will the rebuild cost less than swapping in that "C" word engine?

Just a thought before you spend a bunch of money rebuilding a 6.2.

12V Cummins can be found pretty cheap and my VE pump 12V in my K30 is about double the numbers that you have in your signature with a much stronger platform, pretty minor mods on the wimpiest Cummins out there.

Oh I want a cummins but my nv4500 is the early Chevy that doesn't work with a 5.9 and my ranger sm465 is too weak. I would be happy if it made the current power and was reliable
