67/78 Big Block Swap Questions

[BMERDOC]

Ok, once again someone is askin about a big block swap. This time its me so...

I found a low mileage, cheap 78 Suburban. Its 2WD with a 454/400 combo. I plan to clean it up and resell it. From what I've seen the market isn't all that good for these trucks and it may be better to part it out.

IIIFFF I do part it out I'd like to keep the eng/trans combo, front crossmember, steering stuff and brakes for my '67. So that I dont miss anything what do you suggest I pull off of it for my truck?

It seems the fuel tank is good, I think the booster to v/c clearance isn't enough when swapping into this chassis. If it isn't I may elect to go hydraboost. Can I swap in the rad without issues? From what I know the motor brackets and mounts will swap fine because I'll be using the crossmember too. Can I use the tranny member? Can I keep the stock exhaust manifolds for now? I can't remember if it has A.I.R. or not. I'm not sure if the tranny cooler lines will go in nicely. Will the steering box connect to my stock column? Im not sure if I can swap out the later column.

If it matters, it currently has a 250/3ott

I know the last paragraph skips and jumps, consider it brain storming. Any input would be awesome! Thanks in advance guys!
