the mark/cont is kinda what i was referring to, thanks wicked. and to dickh, any particular websites as to where i could find these aviator engines? I'll keep this all in mind, but for now engines are my last concren (unless mine dies then ill just do a npi short block with my heads) my next project is sprucing up the interior then either a MM k member kit or a TA

Has no one even brought up the fact of the weight of the Iron 5.4 vs Alum 4.6? Even if the HP numbers are the same and the cost is the same, the 4.6 Alum will walk away due to weight savings...and not to mention taking it off the front of the car where its needed.

You spend your XXXX$ on a 5.4 2v...and Im SURE I can build a faster 4.6 4v for the same price. 2v < 4V. 4.6 weight < 5.4 weight...so far 4.6 4V is the winner easy. Plus not dealing with header issues for the 5.4 swap...or intake issues...or the tight clearance between the hydroboost and head/valve cover...and lastly, a 4.6 4v motor fits under the stock hood.

I literally had a stock avaitor motor, with a lightly extrude honed intake (didn't look like much at all), crower cams, longtubes, clutch and 4.30 gears and it was super fast and fun. I still hold the HP record for that build. 363rwhp NA. What NA 2v 5.4 you see make that...and if it does...I know Im 100+lbs lighter...which is a huge deal...esp out of the hole...

I really dont see the point of the whole debate.

I mean with what I have planned for tax time this year. I should be able to break 10's on a stock motor with ease in a full weight street car.

The debate is ppl just don't know whats better or worse. There are ups and downs...I guess the ONLY up for the 5.4 is cubes.

And you could run 10s on a stock 4.6 4v as well. look at modular speed. Stock motor, on3 kit...ran deep 11s on motor...340rwhp. Now has 46xrwhp. I think thats good/deep 10s...

Hell if you want 10s on a stock motor cheap. Buy a fox. throw an aviator motor in it. Carb it. Take out some weight. itll go deep 11s...easy. Should go 10s when done right.

But that isn't what we are tlaking about here. Its about 5.4 2v vs 4.6 4v.

Used Longblock 5.4s can be had for cheaper than a 4.6 4v and are more plentiful, 4v cams cost significantly more than 2vs so that puts extra money right there, idk of any intake problems but there are limited intake choices.. Weight is more than an aluminum 4.6 but 30lbs more than an iron 4.6

Both can be fast cars and are different motors the 4v is a superior NA design.. thats why it was used in the cobras, machs, marauders, ford GTs, Mark VIIIs,navigators, aviators

There is no right or wrong if your goal for the car is to have low weight and big HP and High RPMS then 4v

If you want high torque low rpm Peak hp car.. 2v ... would be a good autocross car

If you want a motor thats better than stock thats cheap 2v 5.4 is the easier and best bet

My stock 4.6 threw a rod and I needed a motor asap.. no chassing down crossover tubes, headers, no time for a tune.. i needed to be back on the road plus I couldnt find a complete 4v for under 1600$..

I had a 2v 5.4 shipped to the shop and I was on the road 2000 miles without a tune under the stock hood and 20,000 miles later its running strong and putting down good numbers

to the OP is all about budget and goals.. you can put in an aluminum or iron 4.6 5.4 2v 3v 4v 5.0 pushrod 5.0 stroker 5.0 coyote 4v 5.8 pushrod 460 BB shit even a new ford 6.2

Ok. So. What Im getting is a 2v 5.4 car wieghing in at 100+lbs more making 270rwhp/340rwtq is better than a stock 4.6 4V with NO mods making 285-290rwhp/320+rwtq? That motor still peaks around 6000rpm. I guess if you want the motor to peak around 4500-5000, go 5.4 2v and no matter what still be slower...sorry its the truth. Not being rude, just stating facts.

I mean I kinda understand a 5.4 low rpm high TQ issue...but the 4.6 isn't far off on TQ than most say it is. Hell the Mach motors prove that...and are plenty lighter. I have less than 2200$ I think in my 32v swap in my 96 GT. I did have some stuff laying around, but I figured in buying that later just for shits and giggles, and I estimated 3k total...done and driving. This included, motor, intake, TB, CAI, Shorty headers, B intake cams, cross over tube, throttle and cruise cables, everything. 3K...that aint bad for a 320-330rwhp/330rwtq motor. Port the intake and itll make 340+rwhp with NO loss in TQ.

Idk. I don't feel that the extra weight for a lower peak HP and TQ curve is worth the effort.

And from your sig pic. That hood looks a little modified.
