There are books that have dyno tested combo's that will get you a lot farther than a forum post to 'help me hop up a 235'.
Most important... what's your BUDGET? You are $1500 in for a rebuild or $2000 for a crate motor.
You can buy a 'warmed up' crate motor for about $3k.
Or you can stick with catalog parts: headers, new intake and carbs.
It all depends on how much money you can spend.
