EFI-DIY, I actually have a 3.5L inline 5 that is going to be turboed and installed in my '85 C10. I recently purchased the injectors and base tune from Limeswap. I'm doing this for the uniqueness and fun of building EFI from scratch. I'm going to try and hide the EFI components as much as possible.

CNC-Dude, any idea how much should be taken off the head or which pistons are recommended? I have found re manufactured crankshafts for just under $200 (I have no core, so I'll have to pay that).
