I tend to agree with Mike.
But here are a couple of things you can play with to keep you occupied.. lol
First you can go to this site:
Link =>
Stan Weiss' - Automotive Performance Software / Interactive JavaScript to Calculate Rear End Gear Ratio needed
Remember;
You have a larger engine now so the torque value will
be higher at the flywheel, assuming the static compression
ratio is the same. If the static Cr is higher, then the
engine will produce more torque at the flywheel.
Volumetric efficiency (VE%) is the highest at 'Peak Torque'.
So with your new engine I would imagine VE% will also
increase.
Moving either to a shorter tire, or a higher numerical gear
ratio will multiply the torque more.
Add the above to a higher flywheel torque value_lbs / ft
and you could simply be spinning your wheels. . lol

Next is a post I made sometime back on this forum:

Yes, eventually the slope of the torque curve turns downward
(because of a decline in %VE) as you indicated above.
The torque curve pretty much shows one the VE% curve
as one follows the other.
So we desire to maintain a high torque curve out to the highest engine rpm that we can.
I have not used this formula for quite some time,
but it might be useful to use it here today, to show
how this works.
((Engine Torque * Trans Ratio * Rear Gear Ratio) / Circumference of the tire.)
The engine produces its maximum force at its torque peak and
its maximum work at its power peak.
Torque does not contain the HP component
but the HP component does include the
torque component.
And finally:
The engine uses more fuel and air, per revolution, at its torque peak.
The engine uses more fuel and air, per unit time, at its horsepower peak.
