In my usual fashion, I've already jumped 10 steps ahead & read about 351W EFI. Seems that there are only 2 ways to fit an EFI 351W under our hoods. One, find a 351 GT40 lower intake & regular GT40 upper, seems difficult & expensive. Two, get a 351 truck lower, a 5.0 car upper (non GT40), and the BCB adapter to mate them.

This weekend I found this item, still hasn't sold. I've never seen anything like it. Does anyone know what it is, or how to get it?

This morning, my friend with the machine shop stopped by and I described the above adapter & discussed the possibility of making one. He can do it, but we had some initial concerns. If anyone can lend advice we'd appreciate it.

#1. Would it sell? I think so. You could bolt any 5.0 upper/lower to any 351W.
#2. Would it be acceptable to make it in 4 pieces? - 2 for the heads & front & rear piece. We thought it could be screwed together, or dove tailed. It just has to stay put till the intake is installed & RTV sets. I see the advantage of the 1 piece design, but he said it would make it many times more expensive.
#3. Would the dizzy clear the raised intake? I'm concerned with the bottom of the rotor housing hitting the top of the lower manifold.
#4. What is the thickness of the adapter? I don't have a 351W block around. But if it comes down to it, I'll get one.
#5. Is there a place to get the measurements of the head bolt/port pattern? He can do it, but it would be quicker if the info was available.

This place makes similar items, the website is down right now:

Any input is appreciated. I think if its done right, it could work, but you guys are way smarter than me, so lets hear it.

Here are pics of the adapter in the Corral classified ad. If you aren't a member you can't see them:

it looks cool, but looks like too many opportunities for failure.
