I guess I’m thinking about the gains vs the effort.
I can’t imagine there not being a gain…….. but how much of one?
At some point the induction limitation would shift from the manifold…… to the heads.
I agree, really there's not much more I am trying to gain. I did the intake wrong last time, I wanted to fix it. I think I have about 50-60 HP leeway before I'm putting my engine in danger of hurting the block.
If I had more time and money I'd put the engine back together as it was just to see what the tunnel ram will do but that's not just my time, that's taking up Dyno time too.
