383 power upgrade help

Hi Joey N, welcome aboard. You have my absolute favorite motor there. My best friend in high school had a '66 charger with the 383.

You will eventually want to get your hands on these books, and others. Search around on Amazon. The engine math book is a MUST, get it before you spend any more money.

I agree with Ottmundr. 383/400s are, or at least used to be, very under rated engines. They will make lots of power if the right combo is chosen, & you won't have to spend a ton of money. Read as much as you can about low deck big block Chryslers as you can before spending dime one. Bigger isn't always better.
