The DOE rates the '99 E150 with 4.2l V6 at 13/17 mpg and the 4.6l V8 at 12/17 mpg. Since mpg is basically a wash, which engine is more robust and/or reliable? Is the bump in HP and torque worth dealing with an OHC engine? What's the service life of the chain, guides, tensioner, etc.?

Thanks,

4.6 modular is a better engine. Parts are plentiful and cheap.

We had the 4.6 V8 in our Lincoln Town car. Put just less then 200,000 miles on it and it got good highway mileage. It always did burn some oil, a quart every 800 miles on the highway. But over the dozen or more years we owned it, put on one set of wires, 2 sets of spark plugs and one time I had to get it towed in when on a very cold morning it could not read the engine position sensor. I think it is a really great engine.
