What intake manifold is best for my truck?

I'm not sure o intended rpm it's a Dailey driver will see expressway time maybe some expressway towing would like power right off idle as well..

In that case you want to concentrate from on off idle to mid range.

That's what I did on mine mileage isn't a big concern for my application.

Yeah, if mileage isn't a concern then it's good..

That's why I still think the Performer RPM is still best choice. Everyone can say why this one or that is better than that one. True, this will do this better, that one will do that better, but the Performer RPM is a good middle ground for a daily driver IMO. If you're keeping the Qet Carb, then the decision is easy, Eddy Performer. The rest are square bore unless you go with one of the other Wiend or Holly Q Jet units.

You'll like it. I had one on my K1500 with a 350 and headers. Real nice throttle response and good power right off idle at a light. Fairly good mpg too for what it was and how I drove it.

Post up some pics after you get it installed.

Nice !!! Old school motor. So did those heads get hardened exhaust valve seats?

Edelbrock 7101 Performer RPM or Weiand 8150 Speed Warrior.

Both are dual plane and will work well with your cam. A Holley/Weiand engineer told me that when used on a 350-383-400, both manifolds give up little or nothing at low RPMs to a Performer EPS and Weiand Street Warrior, but work a lot better above 3000 RPM.

Yep! Hardened seats magnafluxed Guide plates upgraded springs 3 angle valve job. I'm just curious how much hp this will make

Should run real good depending on the cam you have. You've got the best Pre Vortec heads you can have. Compression should be real nice.
