Overhead Cam Timing - 4.6L Ford Engine Rebuild - Build A Panther More Power (Finally)

A rebuild for the 4.6

Photography by

At the risk of losing credibility with our readers (assuming I had any to begin with!), I must admit to never having built an engine before. I’ve done general maintenance, bodywork, welding, complete paintjobs, and even rebuilt a couple of automatic transmissions, but I’ve never taken an engine apart and put it back together—until now. People I’ve revealed this to usually have the same reaction: Couldn’t you have chosen an easier engine to build than the 4.6? My response is always the same (and I hope I don’t sound smug when I say it): Building this engine wasn’t that hard.

I mention this potentially embarrassing truth not as a means of publicly patting myself on the back but rather to inspire our readers. If I can put together an overhead cam 4.6L Ford engine, so can you. To my relief, it started and ran once I got it back in the car. It runs even better now with at least 4,000 miles of daily driving and almost 30 full power pulls on Westech’s chassis dyno. No oil loss, no scary sounds, and best of all, it makes nearly 70 more horsepower and 50 more lb-ft of torque than before, thanks to Trick Flow Specialties Top End Kit for 2V Modular Ford engines.

Don’t be fooled by this car’s two extra doors; this same build will work for any SOHC 4.6 or 5.4L Ford engine currently running in millions of cars and trucks—SN-95 Mustangs, Thunderbirds and Cougars, Town Cars, hell, even F-150 and Econoline van owners can do this job and reap the benefits of Trick Flow’s 4.6 Twisted Wedge Top End Kit.

I wonder how the fuel economy is with that big cam?  228/230-degrees @0.050" lift?  That's cam is just a little bit smaller than the cam that is in my 12.8-second Trans Am.  The TA has great drivability, performance, and the only thing that it can’t pass up is a gas station.  It is definitely not a realistic daily driver, but then I’ve never know the high performance press to be realistic. I find the dyno chart interesting as it doesn’t show the improved power much below 3K where most of the daily driving would be   I do have to give Car Craft a nod for doing something that didn’t involve a Camaro.  Some have called them Camaro Craft for good reason.

lol hypacrites... ford people do the same just like ricer lovers and anything else..... everyone brags!! They used caprices in new york since 66..... i think its called research, i worked at ford and still admire chevy's more becuase everyone looks down on them to be slow and unreliable when there quite furiously the opposite!!

The Crown Victoria is to Hot Rods what Justin Beieber is to music. No shortage of supporters, but still fundamentally wrong

Because when u get beat by a 4 door grandpa car that's got a blower under the hood it makes people go home crying that's why some people like to be different instead of modding an old muscle car or a Camaro or Mustang, some people like to do things differently just because it has 4 doors and is heavy doesn't mean it can't kick ur ass if built properly

I like almost anything on 4 wheels but I have to say as far as our company vehicles all 4.6, Ford has done well by us. 08 Econoline 250 205,000, 02 F-150 155,000. Both work everyday without any issues. By the way we do have a Chevy Express Van with 110,000 on it. Its sitting behind the garage with more problems than we can afford to fix so we can't use it. ;)

14 years with a national truck rental chain as a fleet mechanic. Ford 5.4L engines in E350 duallies, we typically got 140K to 175K before they were sold out of our fleet, with many miles still left in them. No harder service than rental fleet. Everyone that drives it has the attitude "yeeeeehaaaa! It's not my truck!"

I racked up a little over 370,000 on a 2000 model 5.4 Triton in a E250 before it spit a spark plug out.Never had the valve covers off. Still had the original water pump. Company decided to cycle it out of the fleet in 2010. The guy that bought it used a "Time sert" to repair the spark plug,and I believe he is still driving it to this day.

Bought my crown Vic 10 years ago, been supercharged for 3 years, other than a built tranny stock bottom end. Most reliable car ever!
