my wife and the nurse were making fun of me yesterday. I was doing math sitting there to figure out my final drive ratio and rpms now with the t56 vs the 833 which was my first plan.
Im using a 3.23 suregrip 8.75 (for now, may step up to a dana 60 and sell the 8.75)
with the 440 and the 833, assuming a 26 inch tall tire. to run interstate speed of 70 mph, I'd be spinning about 3000 RPMS.
Now same engine and tire, with same rear, using the T56, I'd be running about 1900 RPMS.
Question is now, is that 1900 going to be too low in 6th gear and should I step up that rear gear? The 1st gear ratio is a 2.66:1 in the t56 vs a 2.44 in the the 833.
