I could talk about the tune but building it is a whole different animal. HK built mine it worked great. There are special things you need to do with the piston on a 4" stroke and need to get compression right. The pump gas element adds some things they need to do to the heads if you want it to live. Also the coolant flow needs to be addressed. We did the tunning and I think we did ok. I had a bit more than 300 on it 
I just wish I knew back then what i know now. We could have went way faster.
