No, I believe that was the Blueprint Engines prototype 3.6L inline 4 block that takes an LS head. I jokingly (but kind of seriously) said they should call it the "Super Duke" in homage to the 151.

My suggestion would be to hit up some of the Fiero forums, or the roundy-round dirt car forums (they mandated the "super duty" Iron Duke in certain classes for a while). Both of those will have way more knowledge about squeezing power out of the Duke.

Forgive my ignorance, but what exactly are you referencing when you say narrowed wheel wells? Like narrowing the wheel tubs in the "bed" to gain more bed space? If so, what is the plan for expanding the bed floor? I ask because the thought occurred to me as well, intending to run 65" 14-bolt...

They actually look just like the one's you need: https://www.novak-adapt.com/catalog/engine-mounts/mmx-wc1/ You just need the block plates and the isolators.

Looks a lot like the Novak kit I ran in my YJ when I V8 swapped it.

How's your fan to shroud clearance? The one picture I could find in the thread looks like the fan blades don't protrude very deep into the shroud and maybe are a bit far away from the edge? The tighter it is to the edge the more efficient it will be, and ideally should be 1/2 of pitch depth...

I'll add this one as well for grins. I know it's technically for a CJ-7, but it's something I grabbed to help me model a replica frame in CAD.

Once I get a good frame model built/procured I'll get into freelance engineering options, but I'll start a different thread for that.

Very interesting. Thanks for sharing!

With all the parts that I'm not going to use now gone, it's time to get serious about piecing things together. I'm challenging myself to have this thing going within the next 3 years. Probably completely unrealistic given the scope of work and my reputation for finishing projects, even more-so...

Too cool!!!

Out with the old...in the with slightly less old...

That's actually incorrect, from my understanding. They are MARKETING it as a "repower" but it was actually designed and developed to be the diesel option for the Nissan Frontier a while back. It never went to full production, and Nissan only ever launched the 5.0 Cummins in the Titan after...

Personally, I will never run a turbo diesel without an intercooler ever again. I had a "1st Gen" non-intercooled 12 valve Cummins in my "Fummins" originally, but on a heavy pull up a long grade melted the crown off the number 1 piston due to uncontrollable EGT's. That was just an empty happy...

Beautiful rig! Glad to see you're enjoying it to the fullest as well!

Flagging this for future reference.

While physically possible, I disagree with that because clocking them upside down would put the pressure fittings to the bottom making it potentially more difficult to bleed the air out.

Yes, but hydroboost also typically puts the nitrogen accumulator right where he's having problems too. Not all of them do, but just something to be aware of before sinking money as hydroboost typically isn't cheap.

Timing setup is likely compromised. Broken chain, or broken gear, or backed off gear.

You know how a Detroit is out of oil? They stop leaking.
