Advantage with

Split dominators on say a 530" or smaller motor with production type heads and stock block with a off the shelf tunnel ram?

In my experience they seem to run better with a single dommy and intake with production type heads but in your case it would all be dependant on the compression and cylinder air flow here. Need a little more info on your build/RPM range to tell.

I don't have requirements in mind.. I was just thinking with our tall deck and spread cylinders how much it could help or hurt on a small ci combo.

Just for reference let's say..

528ci
Full race port tfs 325 heads
A custom solid roller
13.1 comp
Rpm limit of 7500
A off the shelf ram with custom top for the split dom's

Waste of money on that type of build IMO.
