Bullshit. Not only does the skinnier 4.6L 2V fit the wide as hell DOHC 4V model fits, as well as the 5.4L 2, 3 and 4V's; the brand new 5.0L 4V, 6.0L powerstroke, 460 BBF hell there are very few high performance ford and chevy motors that have not been stuffed inbetween the frame rails of a ranger.
If the OP is going to put a V8 in I would step out of the 90's and ditch the 5.0L. A stock 3V 5.4L would be a perfect ranger upgrade. 300HP/365 lb-ft stock mated to a good auto transmission that has proven to yield decent gas mileage wwith the heavier F150. You would have as much if not more into a 5.0L pushrod swap to get similar HP. Not to mention the 5.4L would be smog legal in Cali.

That makes zero sense. that means when i finish rebuilding my 1958 oldsmobile 371 engine it will be a 2012 engine and will need fuel injection, cats and a control module to meet 2012 requirements.
Maybe they guy meant a crate motor from ford? I know for sure that when you swap in a newer motor to an older car, you have to meet the emission requirements for that year motor. you could use an older motor and than try to fit on all the emission stuff you need for your 2003 in order to pass but that seems it would be hard to pass visual inspection and would probably have to go to a "referee" or someone like that. i cant remember what they actual title is but basically they just do the tailpipe sniff and as long as you are running clean from the pipe you pass smog.
He is wrong as far as rebuilds. Maybe a shop rebuild with Cali smog hookups. The motor will have to be OBDII with full 2003 Cali smog to pass in a 2003 ranger.
