this sim requires all of the mods in my sig and the biggest comp cams with springs and a good dyno tune.

keep the rpm's below 6000. the cams are advanced 4 degrees from stock specs for the CC's.

biggest CC 3v cam, open exhaust using my estimated 400cfm exhaust. unported 3v heads.

 

the stock intake runners hurt the power by 50hp. but exceed 410 lb-ft at 3500. with the smaller cam.

 

So the comp cams posted a while back are exceeding the stock fwhp by around 30? You can change out the stock intake runners right, and how much will that run you.

 

i have run the sims on all of the cams using the stock intake runner length. the 127300 is the one that exceeds 410 lb-ft. hp is around 345.

the bigger 127350 with the short runner mod, get as much as you can stand. that dyno sim was cut off at 6000. the cam can be retarded and better exhaust added for even more.

add ported heads 269 intake cfm and 208 exhaust cfm and it goes wild.

 

ported head specs short runner

399 lb-ft @ 4500 rpm
422hp @ 6000 rpm


stock runners:

404 lb-ft @ 4500
389hp @ 5500


that's with the biggest cam 127350. that cam is way too big for long runners and small plenum volume that goes with it.

 

if you guys keep the intake stock you can still get big numbers. especially torque. this program is recommended by the one and only Ed Olin. its called engine analyzer pro v 3.2.

http://www.performancetrends.com/download.htm#eapro

you will find it to be amazingly accurate.

 

i noticed the stock cams limit these badly.

stock 178in/198ex @ .050 cams are tiny for 330 cuin.

there is little you can add to the motor outside of cams to make more than 280rwhp. 332fwhp.

 

I'm probably in the neigborhood of 280rwhp and 340rwtq as of right now, but it took more than I'd hoped to get here (dyno numbers in sig are pre-cat delete). How much are these cams and how much of a task is it to install them. I'm pretty handy if you look at my mods, lift etc but I have yet to venture this far.

 

you need springs with them also. i haven't swapped them yet. i had the cover off when i first recieved the motor, but i didn't take the phasers off. i have been told there are springs retaining the exciter rings that need to be watched. i need to get a manual soon. i'ts going to be that same as 2v aside from that. i will make the tooling to swap springs with the heads on. move piston to TDC compress spring and remove. reverse.

it's a job, but worth it. these stock cams murder power. 280 is about all i can see us getting. they even make short runners help very little. i may be slower as a result of lost torque and little HP gain. cams once again. the intake is not as big of a restriction as cams. add big cams, and that changes.

 

I'd definitely purchase this but I have to re-read nearly everything you type. You're a little over my head, some of these words I'm hearing for the first time. Can you spit out some hard numbers, (price breakdown, possible gain breakdowns, etc). Thanks for posting but keep it simple, you're losing us.

 

ok, sorry.

the best torque cam for 5.4 3v: 127150 compcams.
393lb-ft @ 4500.

the best hp cam is the biggest compcams. 127350

388hp @6000 with short runner and all bolt ons. stock heads.

the HP/TQ figures need to be adjusted +- 7%. these sims are a way of evaluating a combo without wasting a lot of money. really josiah , you have what it takes to make big power once you add the cam. you should expect 38o fwhp with a good exhaust.

a good exhaust is defined as follows:

1 5/8" shorty headers or better
2.5" O/R 'x' pipe or better
3" IN/OUT mufflers
turn downs/simple 3" 90 degree outlet in front of the tires.

best exhaust is defined as follows:

long tube 1 5/8" to 2 1/4" stepped headers with 3" merged collectors
24" long x 3" collector extensions
3" mufflers optional
nothing else

the best exhaust MAKES power - - - the good exhaust saves it.

all boltons and good exhaust with 127350shouldmake 380 fwhp / 390 fwtq. that's 80hp gain over stock.

with all bolt ons:

right now the cams are the bottleneck
next the heads are the bottleneck
lastly the intake manifold is the bottleneck

The exhaust is a key in the motors to making the biggest power. if you modify everything and leave the exhaust out, you leave a bunch on the table.

these heads, even in their maxxed out ported form are the limit for power.

269cfm intake flow is not enough to get 500fwhp.

to approach that power level:

12:1 CR
solid lifters
custom cam: 227in/239ex duration @ .050 with .600 in/ex lift. duration@ .200" 136/169 with 30 degree max lift dwell.(the cam sits at .600 for 30 crank degrees)
huge valve springs
open stepped header exhaust
80mm throttlebody
short runner intake mod
racing gas.

that gets you ~465hp @ 6500

 

pricing. bamchips sells the cam/spring together.

a tune is required for the huge cam. they are supposed to be good with 3v's.

at least they sell the kits. if you have a tuner you like use them.

 

assasinator, Not to hijack the threat but did you race this Friday. Since I live so close to the track, I finally stopped by to check it out.

 

no i ran into tuning problems it was running rich and it foules a couple of plugs. i'm going asap. i'm driving a laser red 96. the stang group i'm a member of will be there. sorry. i plan to try it again this friday. the car is running fine. i fooled around with the fuel and got bit. i also had to fix an idle issue. little things add up. i'll post a thread friday afternoon if it's a go. i'm hoping for 84mph. but i may not gain anything. we'll see. if i stay ewith 3v for long i'll put the cams in. this is rediculous that ford hijacked this motor with tiny cams.

Ed Olin had special cams only he could get. it really explains his power. we'll see. i have everthing i can add. i may open the exhaust between now and then and if i can find a 170 thermostadt. the stinkin tuner flash memory error24 went bad, so my spark is stock 4.6 2v. it may hurt a little.


EDIT: the club is meeting on saturday. my wife tells me one or the other. stop by and visit us at:

Saturday June 17 - This is our regularly 3rd Saturday of the Month Meet. New Summer Hours starts!!! Meeting at 6:30pm. Fire Mountain Grill parking lot on Wilma Rudolph Blvd exit 4 off Interstate 24. Bring your chairs, this is a meet and greet with a short cruise likely afterwards.


see ya. -bill
