Question: Can a 4.0 litre SOHC engine in a 2 wheel drive 1999 Ford Explorer XLT with trailer tow package (3.73 rearend) be replaced with a 4.6 litre SOHC engine? Is this more trouble than it's worth? Reasons considering: Now towing a trailer weighing in @ about 3800 lbs with about 450 lbs tongue weight (about 2/3 of spec'd tow capacity)
Any replies would be appreciated.
Thanks, Hergi.
