Finally My Build is starting but need some advice!

[C10ENVY]

Finally tracked down the truck I plan to proceed with.
I was on the hunt for a 67-68 as I obviously like the front end better than the bull nose hood. But I thought I was stuck looking for a 68 as majority of 67 had a small back window.

Found a truck it was posted as a 67 SWB so i start flipping through all the pics and she obviously needed some love but then i came to rear picture of the truck and it had the big window. I thought oh boy here we go another truck made from multiple trucks. I then asked seller for the VIN plate and build spec sheet in glove box. Doesn't matter too many people but what i found out next had my chin on the floor.

Factory SWB 115 WB 67 with 327, factory air, Power steering, Power Brakes, Custom sport truck option, and the Panoramic Back window option!! Also has the 12 bolt as you can see in the pictures if i get them to load.



Truck is rough but cab is solid, will need a drivers bedside as it is full of bondo and bed floor is bad.

Truck had been a project for the father and son but soon after they started the project the father had a stroke and then a few years later he passed. The son wanted to move forward building the truck In memory of his father and did so until news of 2nd child on the way. My father also had one of these trucks and this has been a dream of mine to build since I lost him 25 years ago. The seller and I came to an agreement and I will be getting the truck next weekend.

Also struck gold on a gentlemen 5.5hours away that has a 2002 Chevy 2500Hd truck with 6.0 LS and 4l80e trans but the torsion bar mounts are rusted out in the frame. I am making the trip to go get the entire truck to drive home as I got the entire truck for less than 1/2 of what i see a pulled LQ4 LS motor posted for.

Here is where I need you guys!

I plan to build the truck as a truck I will drive everyday that weather permits.
Goals are as follows
6.0 will be a 408 stroker with the plans of 500hp/tq to the wheels N/A but it will have boost in the future after truck is done and recoup from inital build. I saw the CPP LS swap kit that had long tube headers, pedestals, mounts with trans crossmember. But again i cant talk to anyone at CPP to get more details on flange thickness of headers etc. Any suggestions on a long tube header that will fit a ls swapped 67 as I may Go with the TinWorks LS swap setup.

I have a spare 67 swb coil spring frame that is unmolested that I got from nothern texas that is super clean. I want to have about a 4/6 drop but done correctly to still be able to plant the power and the truck be nice and nimble. I have tried to call CPP as I like alot of their products but had several questions. I have sat on hold for over an hour at a time to get through to someone and eventually just hang up.
So with the guidance of a gentlemen from the forum he gave me some other known names for suspensions and 1 stop shops to get most of the stuff I will need.

Then i came across Tinworks and holy cow, really impressed with his work. But I do not have the budget for a proper air ride system so i plan to use most of his pieces for the rear other than the bag kit as I will likely just install drop coils at this time. I'm still somewhat confused on what shocks to get if using shock relocation mounts to allow the shocks enough travel to not ride like a covered wagon.

Front I plan to use factory Arms after replacing all the bushings, then someones 2-2.5in drop spindles with hopefully disc brake conversion kits for front and rear. Would love to get all the Willwood pieces but being a truck that will likely see 10k miles a year I dont want to be limited on replacement parts when needed like pads/rotors etc. So I saw the CPP kits but again not being able to actually talk to anyone about the products makes me feel like customer support will be ****ty as well. POL seems to have the same kit as the photos almost even match CPP. Would love to use the Mcgaughys but when i contacted them which was a good feeling....They have supplier issues and likely wont have parts to assemble the kits until after the first of the year....UGH!!! Suggestions? i want a slide on style rotor for front and rear along 13in min for front and 11in minimum for rear. I do plan to run 18in wheel min possibly 20in so clearance will not be an issue.

All input welcomed just the kinda person that wants to set it up correctly the first time and build it to last but it will not be a garage queen and will need to be able to service everything when needed without issues of parts availability. I also dont want a huge over lap in cost so if something would cost 10-15% more now to be at the next level vs a much larger expense to change later, then i rather do it now. Prime example doing coil springs now with possibly converting to air ride system in the future.

Thank you all for your time and help in advance.
