The finally test fit went well, tomorrow il be welding in the new bracket and adding a little more transmission pan clearance.
Time for a v8 swap
- Thread starter TrasH Hawk
- Start date
Final test fit was successful, next step the atlas transfer case install and fitment.
Well my day started off good , took the transfer case out of the box and placed it down on the foam packing it came in to give it a nice looking over and I found some damage. Im going to call advanced adapters tomorrow and see what they can do maybe I can just get a new clocking plate.
Trust me these are probably my best welds after a few years of practice but thank you. Only piece of advice I can give it start trying to stick metal together until you get it right.
I spoke with advance adapters this morning and sent over pictures. The gentleman assured me theres no way the case could be damaged but he will look them over and quote me for a new clocking plate. Luckily I kept the box apparently they have customers sending cases back to be regeared / reconfigured all the time so thats nice to know i can just ship it back and have it regeared. Looks like the transfer case shifter assembly and exhaust system are next up on the list.
Finally had time to put the new retainer plate assembly on the transfer case. The adapter plate fit nicely a seems to have increased the angle of the drivetrain by 1 degree which is nice.
The part ive been dreading the most the Y-pipe. I let the engine sit for a week with the stock pan off and loosely bolted the holley 302 pan up. I ordered a bunch of 3in y pipe 's and it looks like I will have to run 2.5 atleast thats what the flange shows.
lol, that was over 2 years ago. I just got a builders kit on Amazon with a bunch of bends and set the axle at full bump and went to town. It went surprisingly fast. Probably only an hour of mockup to get to that point.
There is a formula out there to figure out the minimum size of the exhaust you need but I can't tell you where I'd seen it from. But on both my V-8's I've don't 2.5" in the Y-pipe into 3" through the converter & muffler then exhaust pipe. My having the Savvy midarm has made it a HUGE PITA to fit a Y-pipe...
I actually have a ebay builders set i might just use the 3 inch y pipe coupler from. It looks like yours routes forward than drops toward the front of the oil pan. Ive seen some oval pipe that might help save some space over the axle area but il see what I can get working. Was there a minimum gap you want to have the exhaust from the engine block/ oil pan ? I was thinking atleast 1.5-2 inchs of clearance between them.
It routes in front of the sump, so under the front portion of the oil pan. Plenty of axle clearance, no worries there, your driveshaft or axle yoke will be the concern that you have to build around with short arm suspension. If you have a different suspension you'll have to build around the upper link as well, but on a short arm there's plenty of room. I wasn't too concerned about clearance to the oil pan, at the closest part of the crossover I bet it's only 1/4" off the oil pan. The oil is in contact with a lot more heat inside the engine than what would be transferred externally through an aluminum pan.
Was able to squeeze in some wrench time after work, what more wrenching. The atlas lined up fairly easy about 3/4 of the way up i started to realize this was is a litter wider than my stock np231. It looks like Il need to remove the factory transfer case linkage pivot completely and possibly massage the tub with my hammer. The length seems to be about the same as before im not sure if the case will clear the rear lip of the skidplate but thats another day.
The floorboard needed some clearance with a bfg. (Edit) while a bfg would have worked a bfh was actually used, I got my hammer and doom references mixed up.
