Building a 383 help

Hey all, I just bought a date correct stock 383 bored .030 to put in my 69 barracuda (which is what it originally had). I've never really built an engine before nor know what to look for, but my dad and I are in a competition on who would win, his 70 Chevelle 454 or my barracuda. Both are 4 speeds and mine has 4:10 gears, I forget what his are but they are slower than mine. I'm trying to build this 383 to have a lot of horsepower and focus on lower end torque for acceleration. I'm looking for what parts I should get, cam, pistons, heads, etc. Thanks for all the tips and help.
