In late 2004 I was looking for an engine for my 64. I narrowed my search to a few builders, Blueprint Engines was one of them. I did end up having my engine built by www.enginefactory.com . They were more willing to work with me to build exactly what I wanted for a very fair price. Blueprint Engines didn't seem to be willing to work with me on what I wanted and often they didn't return my phone calls for days. I worked with Matt at EngineFactory and have been very happy with what they built for me.
