1st ET's with new engine

My daughters tricycle wheels are to tall for 3.27's at a drag strip with your combo ! Get ya some gears bud, then hang on. That combo unless your car weighs as much as a tank should run on the low side of 12's at least.
Try 3.73's or if its not a daily driver maybe even 4.11's
Oh what the hell ... if you put the bottom end together with good parts, reinforce your seat so it don't snap off and put 4.56's in it

All joking aside, decide what RPM your horsepower peak is at and choose your gearing accordingly
