Steve's Nova Site is an automotive enthusiast website dedicated to the 1962 - 1979 Chevrolet Nova, Chevy II and Acadian automobiles. We work together to preserve, restore, drive, show, race and provide fellowship for these classic cars. This is one of the best places to find information about parts, rebuilding, restoration and racing. This website is not affiliated with GM, General Motors or Chevrolet in any capacity.
It's a matter of matching parts. Your cam grind lists the power band from 1600 to 5800 RPM's. An Eddy Performer lists power gains from idle to 5500 RPM's, with the Performer RPM power gains at 1500-6500 RPM's. The Performer RPM would match your specific cam grind and give you the most performance available. Combined with your stall, you would have a great package with your cam and the Performer RPM. I would probably top off the combo with a Holley 650cfm double pumper. One thing I've learned from this site is you can have all cool parts but if they don't jive with each other, you've got an expensive hunk of metal weighing down your front end
By the way, what brand is your converter? I'm currently looking for a 2200 to 2800 stall.
Remember 2 things here. 1- Your cam was designed for a 350 so it will act a little bigger in a 327. 2- A Performer manifold will act bigger on a 327. A Performer RPM will act bigger yet. They were both designed for 350s. If you were doing 4.56 gears and winding to 7000 rpm you would pick parts for a 350 doing 6700 rpm with 4.10 gears. An old Chevy Z/28 high rise would be perfect.
Boss Hog, I have had a few of there converters even back when they were Alabama Converters and they have been the balls. $200 with free shipping!
Awesome. Thanks. I'm looking at buying their brand and I found a 2200 to 2600. I'll look again for a little higher stall. They're not to far from me in Madison.

Yep The plan is to move bigger in unison and not over do it at the same time. The reason I went with 10.5 compression is so I could fully utilize the head/cam combo I picked out. What I want now is to match the carb which is math and we seem to be discussing on another thread. The manifold is another story, too much rise and I lose bottom end but gain velocity/high end. Not enough rise/crappy runner design and I lose atomization/velocity and don't fill the chamber... I'm leaning towrds the Performer, I can always add a spacer if needed.

The Z/28 intake is a good one. But the perfomer RPM has been proven to be better across the whole power curve.
IMO running the RPM or a Z/28 intake would be about the same as running a performer with a 1" spacer. Personally I like the look of the RPM. I had a 383 with a 268 cam and 10.5 to 1 comp and I had called Edelbrock and asked them which manifold to use. The recommended me to use the performer to make more torque off idle to 3200 RPM vs the RPM given my particular combination. It was going in a truck not a street car.
