Precision Industries Torque Converter
Look no further than Precision Industries' Vigilante line of torque converters for the LT1 engine. Their single-disc lock-up converters have helped propel many a bolt-on LT1 car into the 12s. Many LT1 enthusiasts recommend running a 3,200 stall with internally stock engines. While it's on the more difficult end of the scale for the DIY'er, this is a mod that can be done in an afternoon-or in about two hours by a professional.

Nitrous Express Wet Kit
Expect 125 rwhp or more from this nitrous kit, which translates into e.t. drops of close to a full second. Along with its high fun factor and great bang-for-the-buck comes great responsibility. Follow the manufacturer's instructions closely, as a poorly installed nitrous system can damage engines, your wallet, and your eardrums when the old lady hears about it. While there are some handy accessories for nitrous, like window switches and bottle heaters, you can get started fairly cheap.
