i have a 94 dodge ram 1500 4x4 automatic now my question is i bought a 509 lift purple shaft cam off a friend of mine but was then told i cant put it in my truck unless i go to a carburater instead of fuel injection because the computer could not read what the cam is doin right which will make it run great under throttle but die at stop lights and when slowing down is this true someone please give me a correct ruling i have already tore the motor apart and am just waitin to put the cam in

 

Need a little more info on the cam, that's not that much cam if that's the correct lift for 1.6 rockers. Need to know the duration, lobe separation, etc.

 

i dont know anything else about i just know how to put in i dont get into all the measurements my friend just said it was a 509 lift and he gave me the lifters to go with it he said it would seriously improve my horespower and be noticeable in the sound becaus eit would lobe pretty hard so how do i find all that out about it cause i just trusted him, cause he builds drag cars but i dont think he knows it either he bought it at a swap meet

 

Are the lifters the rollers? Sounds like one of the performance cams for the LA engines before they went to roller lifters.

 

the lifters in the truck now have rollers on the bottom of them but the new ones with the cam do not but they are longer than the ones in the truck by quit a bit

 

Duration: 292/292
@0.50": 248/248
Overlap: 76 degrees
Centerline: 108
Lift: .509/.509
this is what i believe to be the specs on it from what i looked up if these are the true numbers does anyone have an answer to my original question about leaving it fuel injected or having to change it to a carburater i thank all of you for your help an hope someone has an answer for me

 

Single pattern flat tappet cam..... pretty knarly at that. No, that is NOT going to be computer friendly, at the very least, you are going to need a custom tune, and that is going to require yet more work. That cam isn't a good cam for a truck, unless you only use it for racing.......

 

its my work and play toy i pull a trailer alot but its 4x4 so i play in the mud as well as i want to be able to shut up all those ricer drivers in town the truck is all stock except i just got the tranny beefed up and i just wanna put a cam in it that will improve my power so if i put it in an have my computer tuned will it work or will it need more

 

i bought it all cam an lifters for fifty bucks and dont want it to go to waste

 

You will hate that cam in a daily driven truck, and it is NOT suited for towing AT ALL. That is a high rpm cam, that will absolutely kill any bottom end you have now. Not to mention that even getting it installed correctly is going to be a chore....... You would be FAR better off picking up something that was actually designed for what you want to do. KRC used to make some good cams...... (206, and 210....) but, they sold out (are watson performance now...) and I have heard some horror stories about dealing with them. So, I can't really recommend them.

Talk to comp cams, or crane, or crower, tell them what you got, and what you want to to do, and that you would prefer that you not have to get a custom tune...... you won't get as mean a cam, and it prolly won't have that hot rod lope at idle, but, you will have MUCH better driveability, will still be able to tow, and you will have a good improvement in performance. (the factory cam's are compromises......) Not to mention it being a direct swap......

Getting valve springs to match your cam would be a very good plan as well, as I don't think the stock heads support a heck of a lot more lift...... would be very easy to put something in there that would get you to coil bind in a hurry. (which that proposed cam most certainly would)

You don't want that one. You will have a very difficult time getting it to run right, it won't do what you want, and will prevent you from doing some of the things that you want it to.
