The Dyno Day at ST Motorsports in San Bernardino was an imformitive day indeed. I've never had my car Dynoed, let alone been to a shop that had a dyno. The dyno Day had roughly 40 SRT-4's and about 9 Mustangs, mine being the only V6.
I was happy with the ammount of Torque, but I was hoping for at least 145 RWHP. Well, I'm about 10 HP shy of it. Oh well. It gives me a base line for when I put my chip in. Other V6 1998's have dynoed within 5 hp/tq with the same modifications.
Ya, it's nice having the 4.2 It's amazing that my car dyno'd that low and is as high as it is now. Pretty impressive if you ask me. I personally wouldn't go the split port route, I think it's more trouble to install than it's worth. The single port design is not that bad, the only real major flaw is the tiny upper plenum. Their is one other flaw in the heads, but i'm not going to get technical. You can make your own upper or buy an aftermarket one and you'll be golden. The split port design nets the 40+ hp by design and by the size of the TB. If you port your heads and intakes well enough, you can use a 60mm TB also and see a major increase in hp as well.

I'll do them for you nice and cheap if you want. $125 for each one and you pay shipping both ways. So I would make it an even $300. I'll gasket match them, and port the upper to a 60mm opening. I have an extra set of heads in my garage too if you're interested in those. PM me or e-mail me if you're interested.
Ok guys, I finally got around to uploading the video. Want to laugh your head off at a V6 on the dyno, here's your chance. Count how many minutes it takes to get to 5000 RPM
