In our many years in business, we’ve always focused on offering high-quality aftermarket performance products for earlier model muscle cars and hot rods. That was until about two years ago. With the ever-increasing popularity of the General Motors LS family of engines, we’ve made a real effort toward creating a complete, well-rounded, and high-quality LS product line. Beginning with our fabricated intake manifolds and valve covers, we’ve expanded our offerings to include cooling, electrical, ignition, and more – all for LS engines. In continuing our reach into this huge market and community, Top Street Performance is proud to announce that we have recently become a vendor and sponsor on the LS1Tech forum. is the leading destination on the web for all things LS. For more than fifteen years, they’ve dedicated themselves to an engine family that would become popular enough to rival its predecessor, the Small Block Chevy. With how-to guides, technical resources, and lists of top-quality parts vendors, LS1Tech has become the most trusted site by LS owners, racers, and enthusiasts. We are happy to now count ourselves among the passionate LS1Tech community. See you online!
