A quick question. l got a CEL just after the engine started to run rough. The code is P0304. A search led me to bad COPs (#4). One of the recommended places to buy is rpmoutlet.com but a search there for the proper COP ask if I have the 4.6/5.4 (2v) or 4.6/5.4 (3v)or 4.6/5.4 (4v). I can not find the info in the owners manual or the stickers under the hood. I suspect that I have the (2v). Is that correct? 2000 Ford F150, with the 4.6 engine. Thanks.

 

you have a 2v

 

Thanks, that what I thought. Is the 4v a mustang engine?

 

not sure but I think the gt's were 2v and the cobra's were 4 valve

 

The the old body style GTs had a 32 valve (4 valves/cylinder) 4.6l engines.

The new body style GTs have 24 valve (3 valves/cylinder) 4.6l engines

The old body style F150s have 16 valve (2 valves/cylinder) 4.6l AND 5.4l engines.

The new body style F150s have 16 valve (2 valves/cylinder) 4.6l engines.

The new body style F150s have 24 valve (3 valves/cylinder) 5.4l engines.

Currently, the only 32 valve 5.4l engine is in the Ford GT Supercar.

 

For 2000, the only engines that were v-8 and 4v were the 2000 Cobra R 5.4L, and the Lincoln Navigator 5.4. You got yourself a 2v.

 

I forgot about he Cobra R... and the Lincoln Navigator...

 

I bought Motoblues from RPM outlet and one was defective I contacted them and never could get a return authorizations. I would not buy from them again. If When it comes time to do it agaain I will get the globals off e-bay at least they honor there guarantees..

 

The first statement is also not true. 96-04 GT's are still powered by 2v engines. The Cobras of these years were the ones treated to 4V engines.

 

And the Mach 1.

 

You are correct. Forgot to mention that as well.

 

Glad I was close, nice to see some people who don't mind being corrected, unlike other forums I've been on.

 

I forgot about that too.

Sheesh.... I dunno what I was smokin' when I wrote that... me trying to be quick, that's what it was... not thinking.

 

I had no idea!!!! I am a Mach 1 SUCKER. I feel in love with the MACH when as a child when I went to classic car shows. When Ford included the badge again here recently I considered getting one. I knew they got the shaker hood but I didn't know they were given 4V heads. Does anyone know of any issues, reliability, drive ability, etc...?
Thanks

 

Nope, they are reliable and quick. Under-rated for sure. Back when I had one and was into fast cars, I saw a *bone stock* 5-speed Mach 1 run a 12.9x. Yes, I'm serious. That guy must have been one hell of a driver. They usually run mid 13's. The auto cars aren't near as fast, they have a different bottom end and don't rev as far. Had a friend with a stock 5-speed Mach 1. I always felt sorry for the guy in the LS1 next to us at red lights that thought it was just another Mustang--WRONG!!
