Oh ok, Yeah I can build anything you want. Engines I'm not familiar with I just refuse to offer advise on part selection and tech shit really. I'm not going to tell you what cam is best or whatever but all engines are the same on the inside essentially. Some are better designed, however.
Where I'm working at the moment is a Jeep specialist so I've been doing quite a bit of different stuff lately. A few 4.7 Hemis, a couple of 1943-5 Willys Jeep engines and a 1945 Dodge Weapons Carrier. Your LS1 wouldn't be an issue
