A rebuild for the 4.6 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.

Ford 4.6 Dohc
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. Mod Motor Cam Timing I’ve come across a lot of rumors floating around online about mod motor cams being installed as many as 4 degrees advanced or retarded from the factory. Wanting to verify this, I checked my engine’s cam timing before removing the cylinder heads. We won’t document the entire cam timing test process here, as we’ve done about half a million cam timing articles in the past 58 years.
The mod motor’s overhead cam arrangement only adds a slight twist to the process in this boilerplate article. Cylinder Head Flow Chart. I brought the stock heads and the new Trick Flow heads to Westech for flow bench testing. The difference is dramatic. There is a lot of potential in these Trick Flow castings.

Stock 4.6 bore is 3.552 inches. On the Dyno The engine fired on the second crank and ran surprisingly well. After fixing the previously mentioned oil leaks from the gallery plugs in the cylinder heads (and fixing an unrelated wiring nightmare under the dash), my car felt really strong running on Blue Oval Chips’ programming for the Mercury Marauder MAF installed in our June ’11 issue. However, Trick Flow recommends reprogramming the ECM after installing its Top End Kit, so I spent the better part of a day on Westech’s chassis dyno, as Ernie Mena fine-tuned the air/fuel ratio and timing. Tuning Ford ECMs requires some sort of handheld programmer that goes between the tuning shop’s laptop and the ECM.
Ernie used the SCT X3 Power Flash programmer I bought from Blue Oval Chips. As a result, my car is now making 70 more horsepower and nearly 50 more lb-ft of torque. The torque band is much flatter than stock, as well, making about 300 lb-ft from 3,500 rpm all the way to 5,000 rpm. The car feels much more powerful and a lot more fun to drive. We’ll have some dragstrip numbers to back up these horsepower figures soon.
4.6 Dohc Engine
New technology to go old school! When you retro-fit a Ford 4.6L or 5.4L (SOHC/DOHC) with a carbureted intake manifold, you'll need this new Controller to handle the ignition chores.
The Controller plugs into the coil packs and sensors of the engine for a direct installation. From a PC, using our Pro-Data+ software, you can program a custom timing curve, a step retard, two step rev limiter and even a vacuum advance. A great system for street rods and retro muscle cars.
Features:. Fire the coils and control the timing on Ford Modular engines with carburetors. Map a timing curve and vacuum advance to meet your vehicle's needs. Program two rev limits and set a step retard for nitrous use.
Connects directly to the coils, crank, cam and MAP sensors for an easy installation. Does NOT control fuel Specs.
