another freaking engine build thread

not really any particular goal i just figure if i have to replace the bottom end i might as well go big. i figure 550 would just be a respectable number for that many cubes. and i know just 300 hp in a duster would be excellent but i dont want to spend 3-4k rebuilding it and only get like 350 when i can spend around 6k and get 550. also im 20 years old... i tend to think with the little head not the big one XD
