building 350sb

[63gmcgirl]

ok go easy on me guys, first time using a forum...
so i built a chevy 350 for my 63 gmc, just built it stock no performance parts at all
built now im looking to build it up, make a decent amount of horsepower and torque. its gonna be a street truck maybe a couple times out at the track but mostly street. im looking for the cheapest/best way to build hp.
i realize id need to change out cam/valve train, intake, exhaust but im lookin for the best specs for the cam, intake, headers, ignition sys, carb that i can get
i dont have alot of cash because im in college but hey i can save up lol.
any details on that would be helpful, i want to build it up right and not jimmyrig it together and hope for the best.

also thinkin bout changing out the 4speed granny gear trans.
any opinions on that?

thanks guys
