Sm 465 = 6.55 first (granny)
Ax-15 = 3.83 first
The Muncie could be a lot of fun IMO.

Yeah just like you said man, Chevy 2.8 V6 bellhousing for manual transmission. Mine is from a 1991 S10 Blazer. I think 1985 up through sometime in the 90s is what fits. I think the Blazer had a T5 transmission maybe. I found mine using http://www.car-part.com.

Sent Novak a bunch of money today. They shipped my parts. Syncros and bushings for the SM465, bellhousing conversion kit for 2.5L AMC to Chevy, hydraulic line adapter, SM465 to NP231 kit, transfer case linkage kit, with Knob. Cha-Ching!

I think I can get the other parts at O'Reillys for a few hundred more. Just Empty Every Pocket!

Just imagine having a Rubi case with its 4-to-1 low range now... combined with the crazy low of the SM465 and still being able to DD it...

Hahaha yeah that would be sick! I think people behind me are going to be pissed. Already just with the 4.88 gears, 4.0 TJs with the stock gears are tailgating me because they can't idle down enough to match my speed. Which sucks for them on long steep 1st gear low-range climbs.

After driving the 2.5L for a few years, you get tired of it falling on it's face. Then you experience low gears, and you are drunk with power! You just want to go lower

I spent the last 6 mos dreaming of an SM420 and an Atlas 4-spd with the 5.0 gears... ran the RPM calcs and it would still be OK on the hghway, 3000 RPM's at 65... with a 540-to-1 crawl ratio.

Got a box from Novak, and picked up some parts at OReilly's. 2 more parts to find before I can get the SM465 ready. I'm having trouble sourcing the YJ 2.5L pressure plate, everyone wants to sell me a kit with the clutch disc. Problem is I am already buying a different clutch disc needed for the swap. The right disc is supposed to be in at Napa in a couple days.

I could use my old pressure plate but I want to install a new one, and be done.

Getting excited about getting my Jeep back together

One of those plugs is the freeze plug(or core plug) where the coolant leaks.The other one is the cam plug.
The plug furthest from the crank is the freeze plug. If the cam plug isn't leaking leave it alone. The cam shaft is right behind it and if you drive it in to far you'll have a hell of a time getting it out without damaging the rear cam bearing, camshaft,and possibly the front timing cover.

Wow thank you for the advice Buzzie! I will remember that when I drop the transmission. I can see how it would be hard to remove, since when you deform the middle inward it would hit the cam.

I've been kind of down in the dumps because my Jeep doesn't go right now. Then I took inventory tonight, and am so in awe of my Novak stuff!

The quality of the machining is amazing, just beautiful work.





Syncros and transfer case shifter kit.

Rubicon Express greasable 1" lift boomerang shackles. Gonna go on the front for anti-inversion, and a little lift.


Sometimes I get tired of working on this thing, but then I get shiny new things that have been custom manufactured for my stuff, and it is so cool
