I started this project long ago, but put it off all summer as I built a 3 season gazebo in the backyard... I've jumped back on it but my other thread is so old now I figured I'd start fresh. See the beginning here....

I changed a couple things in the plan since then, such as putting on aftermarket fuel rails and lines. The 2v rail was too narrow on the crossovers, didn't want to run hose clamps to widen it. The 3v rail could be made to work, but the fittings to do so added up to enough that I just went with new rails. I had also planned to make adapter plates for my 2v headers, but due to time/cost just bought them from Logan Motorsports as they have dropped the price since I first talked to them. They were $180 including bolts, here they are in place....



Anybody with kids knows the "cheese" face....

The intake manifold butterflies have a plastic plate that holds everything in, a few screws and you can pop it off and remove the butterflies and shaft...



I cleaned up the insides a little, refitted some little bushings at the sides of the runner, and filled the voids between with silicone...



The silicone fills all the way in between runners and the passages are oddly shaped inside, so it should be pretty secure even under vacuum.

Next up will be to finish brackets for the fuel rails, finish running braided line, and to install the cam lockouts, more pics to come....

 

so whats the plan with the cams and cam phasers?

I'd love to do this swap but dont have the space, or the ability to have the down time of my truck

 

Lockouts, only costs $50 to get rid of the VCT...

gotcha, any other modifications so far?

 

To the engine? Only what it will take to get it installed. I debated for a long time about doing ported heads or cams, but all the little stuff to install it ate up my budget.... I may well do cams down the road, they are very easy to install if you stay with grinds that don't require springs.

 

Yea i meant what all was modified to get it to install and run.

I know how the budget thing goes, it adds up quickly, kinda have to plan in the budget a couple hundred, ahead of time, for broken stuff or other misc items that might be needed before its all said and done

 

glad to see this back in swing, there's been others asking about this same swap

 

Why does this motor have a flimsy, El Cheapo, intake manifold? What was FORD thinking?....

 

Its cheaper that way, plus it will atleast last past the warranty on the truck

 

Thats what the thread is for.....


Whats so bad about it? Ford had problems with early 2v versions that didn't have an aluminum coolant crossover, but other than thats its much lighter, cheaper to design and produce, retains less heat, and has a smoother interior finish. Looks fine to me....

 

The has to be a much nicer aftermarket Aluminum Intake manifold out there somewhere?...........

 

Why? The plastic one works fine.

 

There are no aftermarket intakes for the 5.4 3v, unless you want to have someone fab up a sheetmetal race intake for ~$1500-2000.... There is one for the 4.6 from C&L, and one coming for the 4.6 from Ford Racing, but those only increase power at higher rpm and lose some low end. The plastic Ford intakes are really quite good for the most part, the only folks who really need aluminum are those who run nitrous and try to blow their **** up with backfires..... Our truck motors really don't need a different intake, the stocker flows well and there is a huge amount of power in head porting and cams, you would only need a different (shorter runner) intake if you want to raise the powerband significantly higher in rpm.

 

I just think back to the days when I had my 1989 Mustang LX 5.0! What a beautiful Aluminum Intake that thing had!....It was a thing of beauty!.....

 

The funny part about that is the current mod intakes are far, far better from an airflow and power standpoint than that old 5.0 intake....its not even close....
