Diff ratio
Hi there, I'm new to the thread, have 66 lemans with a 400 and original powerglide, car was original 326 engine. Have purchased a Tremec 5 speed to put in .68 overdrive ratio and running boss 17 inch wheels, 215/50 series, I'm not a burnout guy but will thrash it up through the gears and be open road cruising at 65 mph, can some one suggest a diff ratio that will have me at 2000 rpm at 65 mph, sorryI'm **** at maths 😀

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
