That jump is plus 28.6%, which is huge. But as said; off-the-line you are still fighting a lo-stall TC, 2700 ft elevation, and lower than stock, cylinder pressure; You cannot make a silk purse out of a sow's ear.
put a 2800TC in it, get the tune right, and never look back.
I'd like to see the result of a compression test.
Yur sig says 256/262/112 @.050.
Ima thinking that is just wroong,lol
Is your engine also a 71? Do you know the exact compression ratio of it
IF that is a 9.2 motor, and
If that cam is really 256/262 advertized (not .050),
then; it will feel like a stock 8.0 smog engine below about 3200, until she begins to get up on the cam. With 3.55s and 25.5 tires, that will be about 23 mph.
That 2700 ft elevation is stealing nearly 15 psi off your cylinder pressure and 10% off your sealevel performance. And the stock TC with this combo at this elevation is probably stalling at under 2000rpm. You cannot bandaid those problems with gears.
But Try and remember how it felt in first gear at 3200 rpm with the 2.76s when you smashed the pedal. Now go do the same with the 3.55s. With 28.6% more Torque Multiplication you should see a HUGE increase in the RATE OF ACCELERATION.This is a fair comparison, because it takes the TC out of the equation, and it puts the cam up on the bottom of the power curve. What you are comparing, is the RATE of Acceleration, or how long it takes to go from 3200 rpm to shift-rpm in a particular gear. If you get wheelspin, the test is invalid. Go to the next gear.
