Hello all, My car is getting old, with almost 140k miles. And while it's running fine now, I am wanting to add a blower in the next year and a half or so, hopefully a kenne bell. My first step was to get some PI heads and some decent cams, as KB doesn't support the npi heads anymore. Now, my second step is trying to build a powertrain that can hold the power. For the transmission, I am planning on having T-45 source build one. However, for the engine, I am sort of lost. For under $2000, is there any good rotating assemblies out there that will be able to hold 500-600 hp? I am planning on using my stock block, if that will work? I know mmr makes short blocks, but if I can save money by using my old block that would be best. What sort of rotating assembly should I use? Any suggestions of where to start?
