Am I dreaming?

Still working on a 1973 dart swinger that my grandmother bought and my dad drove off the lot with her in.

Originally it was a slant 6 and I was going to “restore” it all original (ish).

I decided to go with a 360 out of a motor home with long tube headers and a intake and a edelbrock 600cfm carb so that I could turn on to my road without blocking traffic forever........

I got a 8.75 SG rear with 3.23 gear and am planning to drive it as my only car......

Is it going to be fine? I am not doing any cam or pistons etc at the moment.

Is it going to have problems overheating or be a pain except for lack of AC?

Ive already spent too much money (more than it will be worth outside of sentimental value) and dont want major headaches.

I told the wife its gonna be fine and that it will run great but what should I honestly expect when its finally done?

Can I drive it to Florida from NC without worry etc?
