Current challenge is going to be to get the LT4 in there. I bought some dirty dingo LT4->LS mount adapters in the hope they might work. They.. won't. I'm going to have to build my adapter plates I think. Also, the A/C compressor won't fit (yet... I'm still thinking about it), and I have no idea where I'm going to mount the oil resevoir (dry sump), and the various external coolers (water to air I/C, etc). That's where I'm at up to date!
