Is the standard gearing in this tranny able run well with the low end performance I did with the engine? I assumed I could change the rear end gearing to get the streetable performance I'm after. This is a truck I will use mostly around town and wanted nice performance.

BTW, I bought an upgraded clutch to handle the added power and resurfaced the flywheel.

Thanks

As Accelo mentioned.... Do This.

Best of both worlds, still have low gear but you also have overdrive. Also easy to do.
