383/.030 to 400-450 hp?

[Dartin']

As this is the first time I have ever built an engine, SB or BB, I was wondering what combinations I would need to achieve the wanted performance and horse power. The car is not going to be a racer, more of a fair weather cruiser. Here are the facts of the engine as it sits right now;
1969 383/.030 stock (except the bore), 4bbl carb
It will be put into a '69 Dart GTS clone with the appropriate BB 727 street/strip trans. and 8 3/4 rearend with 3:55 posi.
I am just getting started with this project, so have a long way to go. So any thoughts or suggestions would be helpful. Thanks!

that's what it comes down to. living in the USA your at least about $1600-2000 better off then any mopar fan in Australia that's just in shipping, anyway any mopar purple cam can't hurt & a 451-474-496 cid stroker would get ya going with stock heads real nice.( change your stock valves for 1 piece s/s ones, you may already have them). I'm getting one of these my self from the USA & having it sent over. 440 source & muscle motors seem to have all the goodies. i also just bought a book called big block mopar performance hp books.it will give you some really good options. good luck.
