400 block with stroker crank is going to want a lot of fuel. Aside from that, you'll want a 1227749 computer and the $58 mask from the turbo Sunbird / Syclone or the custom $59 developed by a couple of Syclone guys and found at code59.org. There are also a few changes needed to run this code on a V8 so you'll want to get some help when you're getting ready to fire things up.
