they were also going to run a 351W but it wouldnt fit, according to ford
The prototype EA GT had a 351W in it and that was a very tight squeeze, i have heard that 11 EB GT's were released with a 351W but I have never seen any official info on it.

The stock intake only flows 136cfm per runner while the E7 heads flow 156cfm, so they intake is the main restriction. You can port the stock intake but even then you will only just get it up to the level of the E7 heads. IMO just get a set of AU Explorer manifolds, they look stockish and I doubt insurance companies would ever know the difference.

The EA GT prototype had the 351W but no EB GT's got them, they all had the GT40 based 5L mustang engine.

I'm going down the porting the inlet path. From data that I've gathered, I can see that the best port on the lower HO mainfold (8) flows 207cfm, the worst (5) flows 151cfm. The upper HO manifold isn't much better with the best (1) flowing 197cfm and the worst (3) flowing 185cfm. Appartently this data was gathered using 'flow performance' equipment.

That data is way too high, looks more like the explorer maifold flow data but even then it is a bit high. Most flow data I have seen puts the highest flowing port (8) at 155-160cfm and the lowest (5) at 120cfm with an average of 140-145cfm. Porting of the manifold is only suppose to give a max of 180-190cfm per runner but that usually requires either extrude honing or for the upper manifold to be cut open, ported then rewelded.

If I had a camera I would get some pics
I used custop chevy pistons (KB) that require finishing off (I think they were 1.1" hieght pins), to get the require hieght and a bit of machining around the skirts to clear the counterwieghts, the rods are 350chev eagle Items that are stronger and lighter than standard ford items.
The ring pack is a little tight and it rattles like crap when it is cold.
The inlet is custom made using Throttles from CA18 nissans (about 55mm but by the time you take out the diametre of the throttle plates area is equal to a 50mm throttle). It uses 16 injectors - 8 at the entry to the heads for economy and 8 at the throttle oppenings for power.
I have the runners at 10" long from the face of the head but I am still playing around with that.
