I'm doing a 4BT swap for a buddy of mine and I thought i'd just post what my build plans are to make it easier for the next guy and to get any advice anyone might have. I'm using the 4R70W tranny with a TCI master race clutch kit and controlling it with a US Shift Quick 4. I'm also installing a deep tranny pan and 1,600 to 1,800 rpm stall torque converter both from Monster Transmissions. I installed new power steering and transmission coolers on the front of the condenser and then mounted a Mishimoto intercooler, model MMINT-UZ, in their place. I'm planning on using a Destroked 12valve to 4R100 gas adapter plate to bolt the tranny to the engine, but it hasn't come yet to know for sure. My dad has a machine shop so I plan to have him make an A/C compressor bracket kind of like the Dodge 5.9 has. I also plant to have him make an adapter for my flex plate. The engine is freshly rebuilt and we'er using 5X .014 injectors and an HX35W turbo; the main short coming of the engine is that it has an A-pump. Any advice would be appreciated, especially on how to mod the A-pump.
