you can lower the ratio further by putting taller tires...
For the Ford that would work, got any or know where I can get a 2.41 set??

The Chevy Van is getting low RPM torque monster 383 with its torque peek at 2000 RPMs...running a 85/90 Camaro TPI with matching PCU with Highway mode able to lean to 16.4 on light throttle and load.

It too could be golden at that ratio, same question where to get a set?

Thanks.

Rich

PS I have a 2.73 already.
