Take out the big block for a 12 valve?

BB is about 650 lb's... a 6BT is pushing 1100 lb's....
I highly doubt they would ever dip an old Suburban, but it is a BIG fine.

I'm talking about wear and tear on the front... not being hauled into a weigh station or something.. 
I'm talking about dipping the tanks for ag diesel. It is like $5,000 for first offense, and $10,000 for second offense. It doesn't matter if it is damn near full of road fuel, it there is enough dye in the system to discolor their test strip, you are getting hit with a big fine.

oh, you replied to my post about weight.. didn't realize you where replying to some earlier post about ag fuel...
Yeah, that's my bad. I don't know why this board requires you to use the reply to icon. It leads to more confusion than anything.

eh, someone told me how to do it, but I do the same, just hit the new reply at the bottom.. lazy.. 
I think you click on a quick reply icon in the post your replying too iirc...

I wonder how ATF in the fuel would affect the dip test ? I know a lot of 7.3 PSD guys run ATF mixed in their fuel......
To the original question, having both engines in question, both in 86 K trucks, for a wheeler I would stay with the BB. The Cummins is the way to go for a DD, tow rig, and most anything else, but I think it's just too big and heavy for an off road only type rig.

ATF will not show up so don't try that excuse, the "dip" test is not see if your fuel is red visual test its a test strip that reacts to the dye. using offroad diesel on road is Tax Evasion, and is treated as such. fines differ state by state but can quickly add up to 10's of 1000's of dollars . Also I have HEARD from a reliable source that they have a special UV type light that will pick up the dye even in the soot of the exhaust pipe.
While I like my 6.2 diesel most of the time off-road, I wouldn't have any desire to go to a 6BT. A friend of mine has probably around $1,500 total in a big-block that has an estimated 550+ ft-lbs. of torque and over 350 HP at fairly low RPM's, but can run up to around 5,500 rpm. It is now fueled by propane which got rid of any issues of running at an angle.
This is more power than earlier truck 6BTs...way more horsepower (first gen 6BT's were only 160 HP) and RPM also.

Not trying any excuse as I don't run either one
.......just curious as I know more then a few guys who swear buy running ATF in their older power strokes 
You do realize that for zero dollars a 160hp p pump engine can easily be bumped an additional ~100hp and over 230 additional ft lbs of torque.....at the wheels........ and for another ~$250 (valve springs and a 4k gsk) will spin to 4,000rpms .....so around 250hp / 600 ftlb's at the wheels with a peak torque around 1800rpms.
Just sayin

I'm just saying they won't buy that excuse if you ever got got caught ATF will run in ANY diesel I pre fill my fuel filters with it. I know a few guys that run straight used ATF ( heavily filtered ) it does NOT have the same qualitys as diesel it will produce much less power and the smell is horrible

Sure you can turn a Cummins up on the cheap but its still much heavier and there isn't much you can do about that. You're also not figuring in the cost and time involved in the swap , and the cost involved in buying/building a clutch/transmission to handle the power of a turned up 6BT
6BT's belong in towrigs not the wheeling rig.

I was just curious about atf, thats all, I dont use it or offroad fuel in my truck so I have no reason to make any excuse pertaining to a dip test.
As far as the 6bt in a wheeler I agree with you, just making a point to the other poster concerning his comment about the 160 hp versus his friends BBC.
De rail over .

I've burned ATF before, actually it was mostly Allison Transynd, lots of it. And hydraulic oil, engine oil, portions of gear oil. Anyways carry on with hijack.

I should clarify, that $1,500 included a complete running rebuilt stock engine plus any modifications (heads, cam, headers, etc...). He pulled the existing engine and swapped in the new one after building it, and then sold the old worn-out engine for some amount of money....so that amount of money is not just modifications to an existing engine. In the morning the truck was running, he pulled it into the garage, and by the next day it was driving with the new engine.
So your "zero dollars" example above does not include the cost of purchasing the 6BT, or the time and money involved in swapping it into the truck. I guess that was my original point.........and I would still rather have the built big-block. Diesels definitely have their place but there is a reason you don't see them in most forms of motorsports.

Well, to that point can you tell me what car and engine has dominated the 24 hours of Le Mans for the past decade?
And honestly I've mentioned it before the last 2 Ppumped 12valve runners I've bought we're 1000$ and 1500$ respectively. Not exactly spendy gear.

fastest deep-V offshore racing boat ever is a dizzle... just sayin... 
it's not a hp/torque/power issue, it's a weight issue imo...

Here the fine is something like 5K, plus 1k for every gallon in your tank. BIG fine.
And a Cummings has no business doing anything but pulling a trail truck to the trail head, pulling a drag car to the strip, or pulling itself to the strip as they can be built to be fast and quick. Other than that they are a boat anchor and have no need to be on a trail.
