I tried answering yesterday but the forum software doesn't like my work or home computers....
I'm going with a MegaSquirt 3, full sequential on fuel and ignition. I have a trigger wheel I'm going to bolt to the harmonic balancer and use either a Ford VR sensor or an aftermarket hall sensor to trigger it. I'm still settling on the cam trigger, either modify the points lobes or I have a few other ideas too. This is version one of the engine, basically throw together parts I have. The next version will be turbo'd and a custom intake and probably custom headers.
I'll update this thread as the forum software allows. It has something to do with the UBBCode.
This is the error I get every time: The host from which you are accessing the board is not recognized as a valid host. This is more than likely related to a firewall issue that is blocking the referer variable. Check your firewall settings and try again.
