thank you to everyone that has replied. i think i am just going to start making her pretty for right now. just small things like new mirrors, fix the interior etc. she runs great at the moment so im not going to try to mess with anything im not sure about. but i might be coming across some extra money so i would like to buy a block and heads and learn from the ground up. im just not sure sure what block to get. 350, 383, 400 small. if u no of a good reason to get either one, (besides that all are better than a 305!!!) please explain if u could. thank you again for everything and your time.
