Last year I built a 609 rear steer rock lizard with 4.3, atlas, 3x9 rear ram, 10" front. Wheeled it for about 6 MO and kicked ass but ended up selling when I had a shot at Richard's old S&N chassis which I have always loved the looks of. I have a growing family and hope one day they will have interest of going.

The plan was to do a 3.9 Lz9, atlas and th350 with steering 9s. Hi9 front and LP 9 rear. I began sourcing parts and found 05+ stuff to be almost non-existent and some things like the Cs being a 6 month wait. I ordered some TG housings and bought a couple junkyard super duty front axles to cut apart and have Cs machined by a buddy.

I sent harness off to Jim's performance and got some header flanges from Devin Brandt as there are 0 aftermarket solutions for this motor.

I also ordered 42" Kr2-s and dirty life beadlocks.

Housings arrived and I was able to see how things may fit and measure for belly height etc. It was at this point I realized that with some work or compromise I may actually be able to do my original plan of JHF Portals 😎😎😎

Andddd we start over and work on selling all the parts I just gathered....

I have also been rebuilding A 60 degree 700r4 I found rather than the th350.
Pic with front portal is when Richard was originally working on fitting them prior to switching gears to the Kalif chassis.

I feel your pain with the change/upgrade to the JHF portals....fortunately, I wasn't too far into my D60/D70 combo before I bit the bullet.

Always loved the lines of the S&N chassis....they look fast just sitting there....lol

Yes I've always loved the looks of them. This year at TH we were on Arrowhead and a whole group of them passed on a guided run. What I really like is it is still a small ~48" chassis yet room for gear or a kid so should be super manageable in the big rocks

Finally got motor/trans/tcase mounted in final position. Had to make a different trans mount on single poly bushing and drill a new hole in tcase adapter then cut down the 700r4 outout shaft

Got a Sand Hollow Ofdroad Speed shifter as well!

I've been working on fighting the exhaust system and overall fairly happy. I ended up going under the torque converter between it and the skid that I also worked on fitting. Its a little close but i think should be fine.

Additionally i received my 2 31 spline 9" thirds with detroits! Ive done spools and arbs previously so interested in seeing how i like or dislike the detroits.

Routing exhaust is a pain....not looking forward to doing mine. Looks like you actually have enough space there however....but it's always tight.

I got the exhaust mostly done then decided i didnt like the lower link clearance and how tight it was to the torque converter.

So.... I redid most of it to go up and over the back of the trans. I painted with three step VHT flameproof then wrapped. Goal is to hopefully get it running this weekend/week.

Had quite the time figuring out guage ports on the motor but think i finally got them all in. Oil is on a secondary oil galley port on the block behind the new psc cbr power steering pump and water is off a similar coolant passage plug on the driver side.

Been awhile... So much has happened. Cs and portals arrived which allowed me to move forward on axle side brackets/tabs, reverify clearances and begin work on ram Mounts

I then got started on ram mounts and while i knew the rams would be lower unless i wanted more chassis chopping, i didnt quite realize how far up and into the axle they actually needed to be for proper tie rod arm geometry, so i did the best i could and actually hshould have went a hair lower. Potentially someday these will get reworked depending on how well it all wirks.

Caster ended up about 7 rear and 7 front. However I wish i would have went less particularly behind. I also got the shifter and controls mounted up and pretty pleased how they turned out.

Just waiting on axle shafts and boots and one trans part as i found out my trans wasnt quite done to par when i tested it on jackstands. Hoping that shows up asap and i can get it to a shakedown. I also need to lengthen the rear driveshaft

Workes on setting pressures and ride height. Ordered a new rear driveshaft since the local place was ending up super spendy to lengthen the old one. I'll probably just grab it from them and do it myself as a spare.
