It is the in-between block looks and measures exactly like the Optimizer 6500 thick casting and has small oil cooling jets however no endless highway logo and some have claimed it is cast of poorer quality materials than the Optimizer but haven't provided proof of that claim.Enhanced?

Are all 95 diesel suburbans 2500 8 lugs or where there any 1500 6 lugs. I'm going to buy one tomorrow and by the looks of aftermarket rims they look like 6 lug rims. Also it's one owner 245,000 miles no accidents according to car fax, which might not be true but looks to be mint condition. How much should I pay for her they want $6000.00
I think it's 6 lug and please before I drive 5.5 hours one way why would you pass on the 6 lug?

The burb does not have an EGR while the Tahoe will. Check your VIN #, the 8th letter in the Burb will be a "F", the Tahoe a "S"
6 lug is basically a 1/2 ton suspension. Not a big deal unless you plan to tow or abuse it by doing something like mudding or plowing. Unless I am missing something, you can upgrade the suspension and axles if you really want to. So aside from the suspension and axle, the rest of the powertrain is the same whether 1/2 ton or 3/4 ton. If the Burb is for a fun family hauler / highway cruiser, a 1/2 ton suspension will work (although you might want to beef the rear with an Active Suspension).
IIRC, the EGR stopped in 98, so the Ho should not have it. As mentioned, check the VIN.
Here are some other basic differences from MY95 to MY99 and Ho to Burb:
> the MY99 should have dual airbags where IIRC the MY95 at best will only have driver's airbag (if it has one).
> the Ho has a weaker rear. Burb's usually had the truck strength rear, but will need to look at the diff to confirm (or get the RPO codes).
> the Burb will most likely need brake upgrades (proportioning valve per TSB, upgraded rear cylinder) otherwise you will continually accept squishy brakes and manage rear wheel locks at low speeds (when they shoes get moist). Tell-tale sign that the PO(s) never did the TSB is that the front pads show wear as opposed to the rear shoes looking like they are new (and chances are they are in fact original). Short version is that the Burbs put too much brake force on the front rotors and not near enough on the rear drums.
In terms of the minor differences in blocks, honestly I would not stress over it. Just do oil analysis and plan for replacement to a Navistar motor when the analysis shows that you have a soon-to-die motor. This could happen today, or 200K miles from now . . .
And for all 6.5's, injection health is high on the maintenance list as the average owner pays no attention to service life. If there is no history of injection pump (aka: IP) or injector replacement, this needs to happen very soon as they have 100K mile service lives; past that and you are gambling whether a hole gets burnt in the piston or cylinder wall from spraying fuel versus atomizing fuel.
While on the topic of the IP and injectors, stock-up on lube to compensate for ULSD as the current diesel is too dry for that generation injection system.
Never seen a factory 6 lug 6.5 Burb.
