I just had Muscle Motors build me a short block this Summer. The workmanship looks very good. I wish now that I would have just got them to build a complete engine because was starting from scratch. Call Eric and double check the prices, the website needs to be updated. I went 512 in a 400 block, stealth heads, 383 RPM intake. Mike @ MM picked the cam and they installed it too. I can't wait till next Spring.
