Hypothetical build questions…
I hate to ask but please explain this.
Well, 1st we know to gain hp at any one rpm, is with a gain in torque.
2nd the main/easiest way to gain torque is displacement the other is efficiency, cr is a big part of that. 3rd VE is second part of that it's hard to improve down low over stock, most mods will make peak torque gains in a higher mid rpms, torque has frown curve. 4th each rpm has a hp% of torque, we all know 5252 rpm is 100% double rpm same torque 200% hp and half rpm 50% hp, but at 1000 rpm is 19% and 2500 rpm is 48%, 3000 rpm is 58% etc... so if you move torque say by 20 lbs-ft with different cams thats 4-12 hp, not saying so it doesn't matter and or what happens down low, so throw any cam into her it just a little extra info.
Oh ya :) So my overall point to the OP was the majority of hp where 2 gear drops to has already been mostly decided by displacement and cr etc... the cam obviously have some effect on torque there but that torque will have a smaller effect on power at these rpms. To make a decent gain in power you would need a huge increase in torque at these rpms.
