Towing Grand Marquis
We own a 2007 Mercury Grand Marquis (VIN# 2MEFM75V27X641091) with the 4.6 liter V8 engine and a 4 speed transmission, I'm a electrician/mechanic by trade so I installed a aux. transmission cooler that...

You know...hard to advise. I believe when Ford was competing against the Chevy RWD Caprice and Buick RWD Roadmaster...both using the small block Chevy V8 (LT-1)...260 hp/330 lbs ft. of torque....5000 lbs tow rating. Then....I'm pretty sure, Ford rated the CV and it's ID twin the Grand Marquis 4.6 V8...at around 5000 lbs towing.
When GM dropped the RWD V8 car line...Ford then dropped the 5000 lb towing limit as they had no large sedan RWD V8 competition.
Those with better memories can confirm I'm right or wrong on this.
Memory tells me the Ford/Merc towing for the full size RWD, sedan 4.6 V8 was the 3.23 final drive ratio....don't know if you have this ?
