I used megasquirt and currently left the VVT disconnected for now.

The oil pan is a 4200 with mod's <- this was the hardest part of the swap. I think though if the truck had the orginal front axle ( I front clipped mine) the 4200 oil pan might fit as is.

The cost of a used 4200 is actually quite low:

With a bit of looking I think this swap could be done for under $1800 complete.

I'm running a ford 9" out of a '78 cougar - its 1/2 wider than the stock rearend. the transmission is a 4L60E - currently shifting the transmission using 2 toggle switches smile and 1 for the LU convertor.

I think this swap will become more popular - the cost of the engines is quite good right now - no one wants them..for now.

Shortly the megasquirt boys will have a version that will support coil on plug ignition and sequential injection. So the EDIS install will no longer be required once the s/w to support the crank trigger is in place. In conjunction with this the megasquirt 4L60E transmission controller is due out soon too. This gives a complete tuneable engien and trasnmission control for most likely under $600.

The one item that MS will not support is the drive by wire throttle control so a earlier LS1 throttle body and adapter is needed.

The rest is straight mechanical fabrication - mounts etc.
