To be frank...the divider would probably even help with a single carb.
As per my " cam essay" thread..half the battle with carb induction on these motors actually stems from the need to run a cam profile thats been ground on a retarded lobe pattern....THIS REALLY effects bottom end torque.
If you want to improve the performance of your motor in the lower rpm range....dump the factory slugs and buy a multi key way chain...Install the cam and degree it as per the cam card..IT'll be a different animal!
I dont think you should spend the money on a stroker with that induction combo. Not picking at you at all just think you would be wise to to just build a solid forged 6.1 using its crank and just get new rod bolts.
Na want to do the 426 thing . not many options out there for carb set up . Nothing that has impressed me thus far. I don't believe the intake is the end of the road . Theres like three ive seen.
