I was initially going to use my previous 3 rotor manifold I had but my friend Walker Morgan convinced me to do something different...

Old manifold







And went with 321 SS (which wasn't cheap) and went with something different... here are some pics of Walker's art work (Morgan Performance Fabrication)





A brushed 321... equal length, bottom mount turbo (first I've seen on a 3 rotor).

One of the issues later we found was that the motor mounting kit I purchased wasn't made that well and the engine did not sit flat. It took us a half day with 3 guys trying to make things sit flat before moving farther along..
