yeh i had found em right after i posted that.. he wants 379 for the 2v ones.. he sure is damn proud of those things.. i think me and mark might could make some for cheaper.. if not ill probably just buy them. but im sure someone else makes them by now.

 

I wish i had a cnc machine...

 

yeh ive got a couple buddies with some machine shops. but who knows if they'd have time to make some for me. and the best thing to make them out of would be ABS plastic so it doesnt transfer heat to the intake manifold thus reducing intake temps. but i prolly will end up forking over the bucks for it. im still indecissive on going 5.4 or sticking with 4.6 id have to buy so much stuff for the 5.4 short block just for a little bit more torque and not alot more HP. so in im probably sticking with my 4.6

 

That's the only sacrifice? Seems like with the 5.4 you would get a stretched out power-band - a longer pull. I imagine you know what your talking about . Is there a significant weight difference between the two motors? Also , I'm sure Neal looked at these specs and weight is a critical aspect in his build. Why wouldn't he opt for the 4.6L over the 5.4 .
Something about my non PI motor , although slightly modded w/type 3injectors from the 2000 crown vic motor and harness along with COP'S and open intake sporting the K&N filter + the flowmaster 50 series (non SUV model) . My buddy's Supercrew's can't keep up with it lol - They have more flywheel HP , but I smoke them from start and anywhere else in the powerband, my 98 supercab pulls away and it pisses them off bigtime lol. I figure the injectors upgrade is the biggest contributor because it never ran that well before I added that.

It could also be because there truck is heavier, not sure..

 

a stroked motor makes alotta of low to mid range power. a square bore or small block makes good mid range to top end power. the 4.6 makes more HP per liter than the 5.4L and weights about 150lbs less. the 5.4 has windage problems, bearing wear, piston slap, and doesnt like to rev even built safely. many will argue it but ill take reliability over a motor that will make a little bit more power for a short period of time.

 

You are probably right, but at 111,000 miles, half of those have been wot, mine is still running strong as ever!

 

HI!... Just to correct you..... a 5.4 is NOT a stroked "engine", (MOTOR is electric) it is NOT a stroked 4.6. The 5.4 block, deck height is higher to allow for the longer rod, thus called a "LONG ROD" engine. Long rod engines produce really good TQ while still making good H.P. The only reason the 4.6 makes more H.P per liter is because FORD won't exploit the 5.4's potential. I have already proven with my 5.4 that 425H.P at the flywheel is ubtainable with low compression. The 5.4 and 4.6 weigh very close to each other. The only difference is deck height between the two engines. About 20-25LBS. The 5.4 has no windage problems or bearing wear problems any different than the 4.6 does. Piston slap is a problem to to the long rod set-up. The after market already has pistons that solve 90% of this problem. A 5.4 can be built to rev safely. My old 5.4 had 210,000KMS on it and was revved to 6800RPM on stock internals for almost 7 years. New built 5.4 has been over 7000RPM. But I limited it to 6800RPM. Mod for mod the 5.4 will make more H.P than the 4.6 due to the increase in C.I's. Though the 5.4 will always KILL the 4.6 in TQ mod for mod. I've had problems with my built 5.4 but none of this was due to parts or design. It all has to do with the idiot engine builder I had build it. Now that I'm having a professional modular engine builder build the short block, hopefully my days of problems will be over. Time will tell....... I guess.

 

Hopefully! These engines have so much potential!

 

I know exactly how you feel Neal. Idiots did the same thing to my motor in NC. Not gonna have that problem now with who built new one goin in there now .

 

Thats a good reason why i do my own.

 

HI!... Your definately screwed then! LOL! (JOKE)

 

So Neal, did you hear I sold the lightning blower and im going Turbo on my new engine?

 

HI!... Ya I read it over on another forum. What size turbo you going with? T-67... T-76?

 

Not sure yet... Its going to be big though.

 

Evertime I get my license it's at the DMV not the DEV

Must be alittle more than just long rods in the 5.4 cause the pistons are going to move the same distance in either case due to the stroke of the crankshaft. You can't increase displacement with just long rods. It's a combo of bore size, head chamber size, crankshaft throw, deck height and correct rod lenght that makes it all work
