Finished welding the valve cover bungs, as well as the intake manifold heat shield bosses.

Valve cover has one -16 ORB oil fill, one -10 ORB to -10 AN breather and one 1/8 NPT crankcase pressure sensor.

Intake manifold has 4, 1/4"-20 aluminum weld nuts to fasten the .018" 304 stainless heat shield. The heat shield will eventually be trimmed to fit the primaries. I also drilled and tapped a couple NPT ports into the manifold.

Custom fuel hat is finished. Just have to fit the 525 ""Hellcat" pump and it'll be good to go. The hat features a -10 AN supply, -8 AN return, 4 wire bulkhead, and a rollover bulkhead to -6 AN that will tee into the factory vapor lines. It's the exact dimensions of the OE hat to fit the OE module, fit the OE lock ring and take the OE O-ring tank seal. This is a good setup especially off-road. The OE module contains what they call a "swirl pot". The swirl pot is basically a surge tank. In the OE configuration, the swirl pot is fed by the in-module regulator through a barbed fitting. Excess fuel is released by the regulator, straight to the swirl pot which keeps the pump constantly flooded by fuel in any situation. With this fabricated hat, the regulator in the engine bay releases fuel back to the -8 fitting, directly into the same barbed fitting. All functions of the OE module will be unchanged, even the fuel level sending unit.

Picked up the transmission today. AW4/A340 from a 2000 Cherokee with 160 K Mi. Got it cleaned up and I'm about to tear into it. Converter is headed off to Import Performance Transmissions in Hawthorne, NJ for some fin brazing and 3000 stall.

I'm having trouble finding the Raybestos Red Clutches. Part No. RCPS-45 is what I need and they seem to be out of stock everywhere.

They guy I get all my cores, used and hard to find Jeep parts is local to me. He has a well organized inventory and he gets parts shipped out fast. So a vendor to keep in mind when looking for OE parts is Rich @ Only Jeep Parts. You can find his inventory on Ebay and Car-Part. He's not lazy and out of shape where it takes 2 weeks to ship out a damn clockspring like most vendors.

Trans is just about wrapped up. I'm assuming that the converter is still several weeks away. I ended up having to just grab a Raybestos high energy friction module and a basic overhaul kit. Red clutches are about a year out. Good thing I tore this unit down. There was some corrosion on the steel parts from sitting in the scrap yard. I ended up replacing way more o-rings and seals than anticipated.

I cleaned, resurfaced and did a driveway cryogenic treatment of every part except the valve body, case and center support. The cryo treatment simply consisted of 30# of dry ice and 3 Gallons of ethanol. The parts reached -140'F.

Now I'm focused on getting a decent flexplate for this setup. Anybody have experience with thicker than stock straight 6 to AW4 flexplates? All I can find are AMC V8 to 727 or 904 flexplates, as far as SFI rated units are concerned. Aren't all AMC flexplates (including 4.0L) the same OD (13.813), 6 bolt crank pattern and 164 tooth? (Except 42RLE tiny converter 11" flexplates)

Flexplate Update: Mr. Olan Teves of "Reactor Products" has accepted the challenge of machining Jeep/AMC to AW4 flexplates (Probably universal, AW4/32RH/A727). It will be an SFI 29.1 rated aluminum plate with a replaceable steel ring gear. His units typical sell in the $400-$500 range.

Received a call from Olan today. He mentioned that the OE flexplate has been 3D scanned and they will begin the machining process shortly. I hope that this product gets some traction so he can machine them in batches and we can have a true high performance flexplate option in the future.

I also received the torque converter today. Pretty quick turnaround. About 3 weeks. John at IPT is saying that it should be spot on at 3000 RPM stall speed. They cut it open, replace the bearing, machine the stator, braze the fins and weld it back up. That pretty much wraps it up for the transmission. It's completely rebuilt with all of the available performance/strength upgrades. I welded an 1/8 NPT bung into the pan for a temp sensor as well. Now I just have to Cerakote the thing.

Impressive build! Have you picked a camshaft yet? What is the intended purpose of the Jeep?

I would like to run the late model, thrust plate style camshaft, but it seems like there aren't any blanks available. Russ is currently trying to track one down for this engine. If he can't find one, no problem, Brian Crower has already ground a custom thrust pin style cam for this engine. Brian Crower, will also soon be releasing new flat tappet lifters for the Jeep platform. They haven't told me much about the lifters, so for all I know, they could just be standard Hylift lifters. Though from our discussions, it sounds like their own, unique design. Camshaft will have .525" lift on both intake and exhaust, 222 intake duration @.050 and 228 exhaust, 115 LSA.
