10's on $5,000 ?

I just want to know (not to drag this out...) how a running and driving duster is further ahead of the game than a running and driving diplomat.
Ok, lets say I use my '74 Duster.
  • rear end is a 7.25. Do i need to change it???
  • tranny is 904. Do i need to change it??
  • small block K frame. Do i need BB mounts??
  • has small block stock exhaust manifolds. Do I need headers??? $$$$ for abody BB headers, I might add.
  • Has small block radiator. Will it work???
  • Has drum brakes on all 4. Will they be sufficient???
Please enlighten me if I buy a good running diplomat how my Duster has an advantage in cost or anything else to get the BB swap/rear end swap done and go 10's???? Whether I put 4k into a Duster or take 5k, spend 1k on a diplomat and do the same swap.

In my mind, the main difference is you’d be starting with an unknown quantity....... that could easily suck up another several hundred dollars worth of non-go fast parts...... all of which would have to come out of the budget.
Plus, some of the possibly needed parts may not be the same stuff you’d have lying around.
It could easily need things like a caliper or rotor, shocks, brake hoses, a radiator that’s shot, etc.
That’s all extra $$$.

That’s the intangible part of starting with nothing but a fixed number dollars.

I feel it’s a clear advantage to be starting with something you know.

Again....... not my rodeo.
You’ll do it your way.
