the MSII computer with V3 board can be had on ebay for about $340. i think you will still need to build a wiring harness. with the new MSII it does ignition control and you don't need megajolt lite. you can use the ford edis setup to run wasted spark or you can use an MSD ignition or one of the other and run it through your distributor. you just have to lock out your distributor. i won't be available to build and test computers until october at the earliest, but i can do them as well and i can mod an intake manifold for you and setup you up with rails etc.

PM me for details.
