Slant six noob

Greetings everyone,

I am looking forward to interacting with all of you. Let me start by saying I have a 65 Dodge Dart GT, and yes it has more than it's share of problems.
I have fixed alot " well not me, a shop did it" So here is a list of what I had fixed so far:

Brake conversion kit:
New manifolds:
New exhaust:
New Starter:
Replaced the instrument cluster for one off EBAY "now I know how fast Im going but everything else does'nt work"
New supsension:
New air shocks:

BAMN there goes 4 grand right there :angry5:

Now some more problems

It over heats like crazy, I get maybe 30 mins on the highway doing 70 and bam my radiator spewes.
I need knew carburetor linkage. " But Im thinking about doing a throttle cable with a kick down kit"

I caught wind of a 64 valiant at a scrap yard, hopefully pick at it this saturday.

will upload picks of my baby this weekend aswell so you all can see what Im working with.
