best cam

[chadomac]

my car is speed density still i know there are some cams out there you can use what would be the biggest one i could use?

[chadomac]

any one know about this one? Comp Cams XE264

[331TwistedWedge]

whats your combo? ... that will determine what you need ... bigger is not always better ...

[mustangrfast88]

personally i would just go mass air then you can add anything to car and not have to worry about it

[chadomac]

wanna stay speed density at this point. i know bigger is not better but you can only go so big with speed density so i am trying to find out what my limits are

[mustang8998]

That number, covers a wide variety of cams. I'm going to assume (yeah, I know) that you are looking a the #35-349-8. I would think that you would have problems, but I'll let the guys with SD experience chime in.

was hoping there were some on here

[2Kblacksleeper]

Sorry Chad I can't help you with this one.

Ill still. Get with you about the paint though. I still need to do my lower ball joints an an alignment.

I had an 88 gt with sd, I put an e303 in it. I did not notice much difference in power or idle. I put the same cam in a mass air car and it had an nice loopy idle and pulled harder than the SD car.

IMO I dont think putting a cam in a SD car is worth it.

you just have to find the right set up that is why the e cam did not work in your sd car it was to big

[1986GT]

I agree with GREAZY. Why even piss with the idea? You can convert to mass air for close to the price of a new cam. Especially if you shop right for used parts. If your just curious about how far you can take an SD car before it doesn't run right. I would just research it because its been done thousands of times already. It really would just be a bad investment unless your not interesed in making more power more efficiently. Your decision obviously doesn't effect me and I hope you have fun and good luck with whatever your choice is. I mean no disrespect at all just my .02.

Crower 15510 might work or just throw some 1.7 roller rockers on it....

[chadomac]

i have got some ideas ive talked to a few guys on other boards that are getting close to 300 hp with there sd cars. seeing how this is just a weekend driver that would be good for me. besides everyone change's to mass air and then they through parts at it where is the challenge in that? fight the norm, dont be a follower and do something different makes for good conversation at shows

[Timido]

keep the stock cam get some 1.7 rockers gt40 or gt40p heads explorer or cobra intake 1 5/8 headers and a little gear. You should be in the 250hp range at the wheels. Leave it SD and you will have a car that is a blast to drive on the street and with some suspension/tires and a little driving you could run high 11's Changing the cam will cause SD problems.

[Rick93coupe]

There's a guy on theturboforums that has a plug in play mass air conversion for 150.00.

got the intake and gear need the rockers and heads trying to find a set of heads now.

[Timido]

Just keep the 19lb injectors. I ran that same combo in NMRA Factory Stock when I had a high mile stock shortblock the car ran 12.40s at 3450lbs with power steering on Drag radials. Get the car down to about 3000lbs with a set of slick it should run great. It was a blast on the street.

[chadomac]

i heard the explorer 19lb injectors are better because of there spray pattern any truth to this?

[mustang8998]

19 pounders are 19 pounders, no matter how you slice them.

Just search part numbers and let us know, if you find different ones! ;)

[chadomac]

hey jeff they are different. the mustang has one hole for spray and the explorer has 4 holes for spray

Maybe you mustang guys can take the chance to inform an F-Body guy. Is there some kind of tuning problem with the speed density systems on mustangs? I know in the f-body world speed density is not a problem at all. in fact alot of guys making alot of power change over to speed density. I had a 93 z28 that was speed density, with a pretty big cam in it and ported heads, made 415 rwhp tuned speed density and was perfect to drive on the street every day.

They make 300whp..... Wonder how much they are leaveing on the table. Your only driving it on the weekend so make it as fun as possable! If you want to fight the norm put a flat head it it. It is the "norm" becouse it works and we all like power why go about it with one hand tied? any differance from the norm sd can not adjust for and for every "hipo" part you buy you only get a percent of the returns and every part after the first the percentage of gain gets smaller

[Timido]

Do the car with the stock SD setup P heads stock cam then put mass air on it with a better cam you would pick up some power but at a $$$. The mass air harness pcm cam metter all cost money.

I made 300hp 350ftlbs at the wheels with un ported P heads stock cam and speed density. You would not want the bill for the shortblock. I bolted the same top end that made 250hp on it to make the 300/350

[Rick93coupe]

Everything I've read says that the Ford speed density setup doesn't like cam changes, that's why when someone opts to keep it, they change everything but the cam. My understanding is that changes in duration is what causes the problem.

[chadomac]

my research has led me to this There is 2 very important things to check when choosing a cam for speed density. The lobe center must be at least of 114 degree and keep the duration under 220 degree. That's maybe why some people have trouble with the b cam: the lobe center is of 112 degree and the duration is 224 degree. The only thing that make this cam compatible with speed density is this low lift of .480. Not all cams can be put on speed density. I'm sure that a lot of people with cams never check what was the lobe center before buying a cam. On speed density, you really need to check this.

[mustangrfast88]

thanks for that info if it was me i would just throw mass air on it and build away

Put 1.7 rockers on your stock cam and it puts you at approx. .472 lift, the stock SD cam has approx. 205 duration at .050 lift.

I'd put heads and intake on an SD car before even thinking about a cam.

[bangingears]

most of the SD cam voodoo is from 10 years ago. You know can install a chip and tune the SD computer? Every other car manufacter with a map sensor can run aftermarket cams, why can't you on a ford? well you can.... If it was my engine I would run a stock cam, good drivability, easy to tune, good behavior. If you must go for aftermarket get a custom ground unit, that has newer lobe technology, good vacuum to run the most resolution on the map sensor for good behavior, and most importantly, the most average power for your rpm range.
If you have basic understanding of speed density fuel injection, you can do quite a bit. We used to run twice as big fuel injectors, scale the map sensor output in half, and you are able to run almost 13psi of boost and let the factory computer add fuel, so the map sensor worked in vacuum and boost.
The problem with Fords map sensor is that it is not a voltage output type of map, but instead a frequency based map sensor. You could make a simple voltage to frequency converter fom radio shack, but why? With basic understanding of how things work, options are endless.

not really buying this, you mean LSA and not LC. The only thing a SD car cares about is vacuum, thats it. One of the engine master engines has a ICL of like 96 or something stupid, a LSA of I think 103 and made decent enough vacuum, and made power down low till redline. My old engine had a 112 LSA and made 18'' of vacuum. A cam designer will place your IVO,IVC,EVO,EVC and the duration, ICL,ECL,and LSA are based off that info. Check the chart

I have a lot of stock cam/speed density from running 3 years of NMRA real steet. I love speed density!!!! But the stock cam is the only one to run. I've been 10.6 @128 w/ 19lb inj, speed density, ported iron gt-40's, STOCK INTAKE, EXPLORER THROTTLE BODY, 306 FLATTOP MOTOR, 1 5/8 SHORTYS W/ 5 SPEED. It made 252 to the wheels on motor. Ran 10.6 on a 200 shot. No BS. Lots of witnesses on the board like Chad393na, yougotjunk, metcalf, 89notch, 347SC, Timido, Vinny(RIP). The car weighed 2850 w/ me in it and went 1.43 60 ft. It had a NOS plate kit between the upper and lower intake. You can do anything w/ SD but change cam or injectors. Hope this helps.

yea this car would get down and leave like a mofo.... didn't you put 300 to it and couldn't shift it fast enough? lol. that car was fun too watch

[todd86]

It was insane on 300!!! the day it went 10.6 I put the 300 on it and it went 4.11 at the 330ft. I had to lift because of grass and walls. the next pas the cross pin fell out of the tracloc and when I left it spun inside the carrier,locked the rear end up and broke the mainshaft in the g-force t-5. I honestly think it had a 9.XX if it woudnt have broke. What would 4.11 at 330ft run? it went 4.4X at the 330 on the 10.6!!! Amazing that 9's are possible w/ such a mild combo. It would have went 9's w/ a c-4 don't ya think!

LOL! Try shiftin a street tranny on a 300 shot. That was nuts. On the dyno it made 252 on the motor and 520 on a 250 shot.I never dyno'd it on 300. But on 250 it made 692 ft lbs of torque. Talk about seat of the pants! Second yellow, floor it spray and pray. Nothin like 300 on a micro-switch!!!!DAMN! LOL! As u may guess it was a little hard gettin the trannies and rear ends to survive. But it was a blast fo sho!!!:D

Loved driving it but I wish I could hve seen it launch like that. I remember vinny askin if i was sellin seats for that ride.:angel:

i say it would have went 9's forsure on a clean pass with the 300 in. that was probably one of my favorite cars to watch...
