Hey guys i have recently acquired a 4.3l v6 vortex engine. This is the same engine that the Syclones and Typhones used, the engine comes with the cast iron block, cast iron heads, valves, valve covers, crank-cam shaft, timing chain, and intake manifold. This engine also comes with the stock turbo charged exhaust manifold. Turbo not included. What made this engine so special is the fact that these GM Syclones and Chevy Typhones could reach 0-60 in just 4.6 seconds without any modifications. If you are interested give me a email xkrazyroguex@yahoo.com
