how many of you have pulled the engines from your car?

The modular engines are easy to disassemble, but require expensive tools and machine shop equipment to assemble properly. They have WAY tighter tolerances than any pushrod engine. You could build one with ease at home as long as you don't plan on throwing too much power at it. The bigger the blower, boost and so on, the more important these tight tolerances become. Even the simple process of honing the cylinders requires expensive torque plates to be bolted in place of the heads to give the same bore distortion simulation as a set of bolted on heads.

I recommend you purchase a couple of mod motor rebuild manuals and not the one Sean Hyland wrote.

yeah, definitely get a shop manual and book for you specific motor. I had one when i built the motor in my lightning and it was a huge help
