i can see low rpm torque and maybe fuel economy in city/rural area's but NO HP gains what so ever.

Bud Mud,
Could you measure the height and width so we could get an idea of area? Might not be as bad as you think. Then again there might be a reason you can't give them away on eBay. It is a very tall port!

Okay...
SP2P - 1.64 sq.in.
Performer 400 (2171) - 2.11
Factory 2bbl. D7TE-SA - 2.34
Weiand Action +Plus (8010, pre-China mfg.) - 2.44
Holley Street Dominator - 2.53
I didn't account for the corner radius, but there it is... And yep that SP2P is tiny! Like to get my hands on a factory 351M/400 4bbl. intake just to have a look. Apparently Ford made a rare but excellent 4V Cleveland intake - spread bore I believe. By excellent I mean better than a lot of aftermarket intakes... apparently.

The SP2P might be a good street manifold on a 351. It has 29% less area than the Performer 400, but a 351 is 14% smaller than a 400. So, it is basically 14% smaller on a 351 than a Performer 400 is on a 400.
