Woops...good news is the chassis is totally overbuilt and there's zero damage, but the 360 not so much.

My buddy and I are good, body wise car is perfect however I sent a rod through the bottom of the block. Pulled the passenger head earlier, no damage on that side but theres chinks of cast steel in the lifter valley so hopefully it's just chunks of the block and not the piston

Well I traded my buddy my diablo trinity tuner for a bare 360 block and complete (disassembled) 5.7 hemi that has a bad cam that came out of his 10 ram. Unsure of which direction to go at the moment. I'm going to pull the starter and header on the driver side tomorrow to see if that head is good to go. I suppose that will make my decision whether to go go with the 360, .030 over with the KB pistons, replace the damaged one and go full forged rotating assembly with a cam good up to 6k rpm or make the car sit and build the 5.7 hemi into a reliable fuel injected 450+ hp. The first 360 was around 420-450 so it doesnt make sense to just rebuild the 5.7 to stock and make less power.

Looks like I'm doing another 360 for the Dart, engine builder is going to warranty his work. Side note, never thought I'd have to clean snow off this damn thing...

Been a hellish 2 weeks personally, but the Dart is now down at my works shop so I can work on it over the winter. Just ordered Dr. Diff's version of the Detroit tru-trac since the thing needed a posi really bad and it's cheaper. Once I have the motor pulled and at the builder's shop, I'm going to asses the damage to the K-frame from going in the ditch last month and see if it needs to be replaced. I also made a parts list to go to EFI if the extra cash is available, come springtime. After a bunch of research, 65-68 Mustang fuel tanks fit between the frame rails when turned longways so a Holley sniper retrofit tank will work for my build.

Tanks inc makes a EFI tank for your model. I have one for my Dart. Hopefully, starting mockup this weekend.

I would go with an OE style tank BUT my floor is cut out for the current fuel cell I have and the mustang tank actually cover the entire area I'd need to replace to run a factory tank. I did see those tanks though, wish I would've before a bit the bullet and cut the trunk pan last year...

Ah! Gotcha.

The past month has been an eye-opener with my personal life, went through some major changes so the Dart has been put on the back burner. All the spare parts for the car and my W250 are now in a giant heap in the shop which will be sorted through, some will be up for sale. Side Note: I decided to treat myself and bought a new daily, 13 Grand Cherokee SRT8. Actually ended up lowering my monthly payment which is awesome.

Finally had some disposable income to start knocking out the parts list. Scored an open box TCI outlaw shifter for $230 on ebay to replace the TCI fast gate which didn't work out as intended but this will end up being a direct swap and upgrade. The motor is the next step: pull out and replace then address the fuel delivery system. Looking back at the original plan I had, I probably rushed the whole build a bit and cut a few too many corner to make the events I wanted to attend with the Dart but the way I look at it, I can still use the leftover and swapped out parts on my W250 which needs some love in the worst way.

Finally go around to pulling the 360 and inspected my handy work....
Ouch!

Well good news on the new engine, FINALLY....my engine builder felt terrible for what happened so he's building a 408 free of charge and fixed the bent valves. Forged Ross pistons and I decided to go with eagle forged rods also along with retrofit roller lifters since were going with a 73 360 instead of a newer style.

Life has been a rollercoaster since May, new homeowner life. Dart's been sitting idle for the time being although it likes the new home in the barn/garage. Still waiting on the new 408 unfortunately, looks like she won't be driven this year. Just gives me time to tear down the car this winter to "undo" and change a few things I rushed through when I got the car running.
SO this winter: new procar seats+brackets, new correct length axle from RMS set up for their 4 link suspension, EFI, new fuel cell to replace the junk JAZ unit, install a roll cage, and maybe some fiberglass parts to lighten this turd up.

Looking at home in the garage there. Good luck with the winter projects.

Finally got my replacement engine back from the builder...life lesson learned. On the plus side, everything is all ready to go minus a couple of odds and ends.

This is the powerplant until I change my mind again:
408 from a 73 360 block zero decked, forged ross pistons, forged eagle rods, forged Mopar performance crank neutral balanced, shaved ported heads with big valves, edlebrock vistor jr intake, prw rocker arms, comp roller cam, morel roller lifters, kevko oil pan. She's going to be topped with holley sniper efi at 9.8 to 1 compression.

Rear suspension update: my buddy came over to weld the cross member in for the RMS coil-over kit, looks like it'll be on all 4 wheels this week and ready to swap in the 408. Then it's the big push to get the Dart back on the road and the bugs worked out, again. The new seats also showed up.

Welding's finished and the 4-link is mocked up. Needed to cycle the suspension from full droop to full compression to see where the fuel and brake lines are going to end up. Everything's looking good, however, I used all my extra AN tube nuts, AN hose, and ends on my W250 so it looks like the car won't be running for the next few days. The new fuel cell fits perfectly though, which is nice. My recent discovery of rivnuts is going to make install and removal of the tank 100x easier by myself.
