I found this over on mustangforums. The cams in green are proven to work with SD mustang ECUs. I don't think its a hugh leap of faith to assume these cams will also be compatible with the truck SD ECUs.

From what I have been told, as long as the lobe seperation is not greater than 114, it should work fine with a SD computor.

 

I can tell you from 1st hand experience that the Crane 444211 DOES work with the truck ECU. Only occasionally do I have issues with idle, but that is usually at startup. Otherwise, she pulls hard all the way to 5K RPM. Of course 4.10 gears help since the power band starts at 1500-1800rpm. Just my $.02

 

Stryder, have you heard any good reviews on the 35-349-8 Comp Cams Xtreme Energy camshaft? How much did you spend on that Crane cam also, I bet it's cheaper than the Comp cams, I just bet?

 

Wow, now your making me stretch my memory. I think cam kit was under $300, and that include matching springs. Havent heard much about the Comp Cam, although from the specs it looks decent. A little less than my Crane with a little more duration on the intake side.

 

I have a 1992 Ford F-150 with the 302EFI motor and I want all the torque I can get from this motor and by swapping a cam in it for right now I think that would be best for my budget right now other than I would be swapping heads probably for some GT-40 heads. I am still running the Speed Density system and was wondering if that Crane will work beautifully with the SD system. I know you said that you have an occassional startup problem, is that in the idle or something else when that happens. I just want the best cam possible for my SD system. I advanced the timing on my truck a little and wow the off idle torque is something else and that is without the camshaft so I know the camshaft will definitely wake up the motor in this truck especially being the 4x4 it is now. I have owned this truck for a good 6 years or so and just love it even though it does have the 302, just can't believe I never messed with the timing of this truck when I got it, I guess you can say I didn't even know how to mess with the timing on this engine until about a week ago where I thought to myself you know what I am bored let's check the timing and sure enough it was on 0* instead of 10* BTDC and I advanced the base timing to 15* and it runs on 87 perfectly without pinging or knocking....

 

The problem at startup is stictly idle. It just wants to lope a bit more than usual. Not a big deal. Timing wise, for my setup, 14* BTDC works great. The heads are E6s with a slight port job with a little more detail spent on the exhaust side. The GT40s should work great all by themselves, but I'd still clean up the exhaust ports. I'm also using the ECU from a 351W truck. Not sure if it made much difference, as the old one was shot and needed replaced. Not sure how this cam will affect an auto tranny. You may want to call Crane's tech line on that one. For torque, you want low duration and high lift. So you may loose a little with the comp cam.

 

Conanski told me that on the 35-349-8 Comp cam was like using 1.72 roller rockers and a upgraded high duration cam believe it or not.... If you know Conanski on the board here he's a regular on the 302-351w small block forum, he suggested the cam to me last night because I recommended the best cam for the 302 as far as torque goes...! Thanks for the feedback though...

 

the lobe seperation must not be less then 114* stock is 116*

 

Kem, you are so right, I stand corrected, Thats what I meant to say.

 

i figured you did, just wanted to catch it before people really got confused. SD seems to be one of those animals ya know.

late

 

Will the 35-349-8 cam work with the stock valve springs with the lift? I thought you could only use a cam with a lift of .500 or less and get away with stock valve springs. There is a lot of good info on this thread!! I've been searching for the right cam for my bronco and it seems like everything i read says something different!! Will the 35-349-8 cam work for sure with all stock valve train components?? Thanks guys!

 

I just looked up the 35-349-8 cam on the summit website and they say is is not computer controlled compatible. Is this a mistake on their part or what?? Stinkin summit isn't making this any easier!!! lol

 

Well if you look at the Crane 444211, it shows a L/S of 112* (supposedly non-SD friendly), but when you call and talk to a Crane Techy, they say it will work with SD...and it does. I'd call and talk to a Comp Cam Tech. They will give the the thumbs up or down on SD compatible. Usually anything with a duration under 220* is supposed to work with SD.

Any lift over .500" and you need new springs. Not sure how much lift the stock rocker arms can handle. That is why I went will full roller everything. Then again I also have 0.530" lift.

 

When in doubt go to the source and trust what they say. Comp Cams says this is an OBD1 computer compatible cam. The pic I linked above.. that doesn't seem to work anymore, is from a mustang forum and they also say this cam is proven to work on speed density mustang motors. Here it is again...
