Performer vs. performer rpm Q-jet

I was just wondering which intake I should use for my truck. It is an 84 GMC short bed 350/350 with 3.08 rear end. I am planning on putting a 383 stroker in the future. I just want to know which intake would suit this truck better. I dont think the engine will be seeing rpm above 5500 very often which is what the performer is rated at. But I have also heard the RPM will give me more performance at all engine speeds.

I would definately go with the Qjet rpm.

Generally, I agree with this thinking.

Either version of the RPM seems to be quite capable at any engine speed below 6500 and it is quickly becoming the "Universal" intake manifold. I like the Holley 300-36 too but the RPM is a little stronger up top.

I have a Performer and a 1910 Edelbrock Q-jet and I wish I has the RPM Q-jet manifold to go with the killer Q-jet. FWIW I have a 383 and it pulls hard. I have 3.08's and getting some decent times up here a 4200 feet. (15.25-ish)
