They are more of a higher rpm intake. Single plane design.
I also have one laying around waiting for use. I was thinking of using it on my 390 for my pickup also. I think it may be a bit lazy off idle, but run like the dickens on the highway!

It does fine on street vehicles. We used to put them on 4x4s back in the day because they wouldn't hurt off idle performance, but really extended the top end. We loved 'em. We were using small Holleys, I used a 600 double pumper, and headers, with great success.

Scouder, what would you say about the Streetmaster compared to an rpm. They were not a high rpm manifold. I just got an e-mail back from an Edelbrock tech and he said they were sold as a 1500 -5000 manifold. I have one and am looking at whether to get the RPM or not. There used to be a mod paper on the Streetmaster but I can't find it anywhere. The Edelbrock guy did'nt want to talk about it.

According to Edelbrock they haven't made them in about 20 years, but neither has Ford made a 390 since then. The X design manifolds were all the rage then and they basically changed the size of the runners and the plenum to change rpm ranges. What the guy told me seems right. I worked in a speed shop in the early through mid 70;s and thats when they made the Torker, Torker2, and the Streetmaster. All X manifolds with differences I mentioned above.

I used to take mine to 6000-6200 quite frequently. This was around 1980. Like I said, we didn't see any low RPM degradation. Also, I almost wrote in my first post that I thought they were a 1500-5500 rpm manifold, but couldn't remember for sure.
Truthfully, if I already had a Streetmaster, I would use it instead of buying the RPM. The RPM is probably a better manifold, but not enough to spend the money. Just my opinion.
