Did they make the intake out of plastic to get a smoother casting for airflow?

I have been selling Ford Parts for 25 years. The 4.6 2v is one of the most reliable engines Ford has ever built along side of the 300 I6.

I had a '69 E300 Econoline with the 300 I6. It started running rough once and a couple days later there was a terrible smell of raw fuel. I opening up the engine cover and found the air cleaner housing rattling around, pulled that and found that the top half of the carburetor was loose and gas was flowing from the float chamber down onto the manifolds.

Tightened up the screws and drove it another 60k+ miles...

Sold my 1992 F150 (300 I6 equipped) in 2001 with 240k miles on it. I saw it three weeks ago still going strong. I tried to catch up to the guy driving but there were too many traffic lights in between us. Wonder if it has hit 500k yet.

Sorry for the hijack on the thread.

I have a customer with 1997 F150 4.6 that has over 700k miles on it. The heads have never been off and it has never blew out a plug.

We have two different 4.6s. The '03 GT and the '04 Mach1. My GT turned 10 last month. All I've had to fix were parts that normally wear, Tires, Brakes, a Battery after the first 7 years. Also changed the plugs on both after 60,000 miles, just to see how they were doing. Could have put them right back in, but of course didn't. Driven hard many times too. The Mach has 84,000 miles, and the same for it too. I love these cars and the engines. I would focus on the last two model years, '03-'04s.
