so i have been looking at the e303 cam and it seems to be a popular choice among 5.0 mustang and f150 owners. my question is can you just drop one of these into a stock 5.0 on speed density? without changing anything. like lifters and such

 

need more info, and if your trucks a 4x4 dont bother. theres a ton of other options out there, and the letter cams are not ideal for a 4x4 truck. paul will chime in on this one for sure. he actually helped me choose my cam for my 96 f150 5.8 4x4

 

dont know too much about them but i had a friend put an e303 in his truck and it took away alot of his bottom end power.

 

it would be going on a 89' 5.0 2wd automatic. and i would figure it wouldnt give you much low end, more so top end horsepower

 

he had good top end power but he also had some other things done to the motor.

 

ok lets start here, 1st your 89 figuring it has the orginal engine is not a factory roller cam. 2nd your speed density. you have a non ecm controlled trans which is good and i see a fox mustang pcm in your future! i think the best way to go about this is to see what casting number your block is and determine what cam to start with . the best way to go at this is with a mass air conversion with a mustang pcm and a decent roller cam. again conaski will see this and chime in . one question needing to be asked is what are you trying to do with the truck?

 

That cam is not SD compatable and it's also a lousy choice for a truck 5.0 even if you have mass air.

 

this truck is basically going to strictly be a street truck, it never pulls anything and rarely hauls anything. i really dont wanna go through the hassle of converting to mass air.. are there any good cams available for a stock 5.0 on SD?

 

I'm also wondering from those that have done it. What is the best SD cam to go with...

My truck is a 351W 4x4 and like Nally427 I have no interest in changing to Mass Air.

 

In an '89 5.0 a good SD friendly cam is the Comp 31-255-5.

You'll want a different cam in the 5.8, for a pre '94 flat tapet motor use the Crane 444232 and in a post '94 roller motor use the Comp 35-512-8

 

Thanks that is a great help... mine is pre 94..

 

Help got 89 f150 4×4 5.0 took off fuel inj. went with carb. Looking to add HP on a budget what's the best head and cam combo ? Have msd dist. and coil , long tube headers , please help .

 

I have no idea why you would do that.

How do you plan on addressing the fuel system to step down to carb pressure? What transmission do you have? If it’s an E4OD then you will need the OEM or an aftermarket computer to run the transmission.
