need ideas on my 68 mustang project car

Hello im new here about two years ago my old man passed giving me possession of our mustang he had it build for me when I was very little about 7 currently it sat for about 10 years in a garage till he gave it to me to take care of a 4.7 liter v8 about 400 hp its very high in torque it has a c4 3 speed auto that's rebuilt but is pretty banged up from abuse :C It has a holley 2 barrel carb it was very slightly oil starved but had it looked just lost some life in my heads :C suspension too soft bottoms out now I want to learn form people and get ideas on what I should do with her she is a very hot tempered car over heats way too quick run at about 230 to 200 mostly had a thermostat changed and she run now at 190 to 180 on mild hot days scorching at around 230 to 240 she shuts down and refuses to start for about and 1 hour after cooling here is her pictures someone show me how to post pictures?

To post a picture you have to save it to a free picture sharing site then post the link. I think there is another way, but I haven't done it here in years and can't remember.
If it is the original radiator, or even the second, you have to replace it. The original just wasn't designed to last this long or for better cooling. My 65 Comet when it went from a 260 to a 289, the overheating back in 1979 was horrendous and it needed a new one. I can't give you advice on the suspension.

400HP in a 289 with a 2 bbl carb? Not very likely but you'll need to get the coolant temps down and the radiator replacement that 65Comet is where I'd start too. Rock Auto has a selection of radiators from $105 to $250. Even have a 2 row aluminum for $126
