I've got a 94 f150 5.0, it currently has long tubes and true duals with an off road x-pipe, E303 cam and matching valve springs, new pushrods and lifters, timing chains and gears. I'm basically looking for a good intake manifold, I've seen the Edlebrock and heard of people doing the Holley Systemmax upper intake swap, what're thoughts?

Thanks,
Logan

 

Is your truck mass air?

 

Yes it is equipped with mass air

 

no letter cams in a truck, bad idea

 

Why's that? It seems to run fine to me

 

What about a Comp Cam setup? I have both, part number K35-308-8?

 

With the mass-air setup, he should be fine.

 

This cam would be much better suited for use in a truck than the E303. The stock heads do not flow much beyond .500" lift so you will be losing out a bit on the return for your dollar. But the low end will return with this cam.

The truck 5L EFI intake is a nice piece, I would keep it.

 

I forgot to mention that I've got the Gt40's off of an explorer too lol. Sorry, terrible at explaining what I have.

 

GT40s are definitely a step in the right direction. I would definitely go with the Comp cam, keep the 5L EFI truck intake then budget for a custom tune to get the most out of the investment.

 

the letter cams do not have the torque range and power band needed to move such a large vehicle . the gt40 heads are a great improvement , the p heads are a pia, I have them currently and have a constant misfire on #4 because I cant keep a plug wire on it without it burning off. in the 96 5.8 I am running a comp 35-510-8 , with 1.7 roller rockers with a performer efi and the dual 61 mm t/b gt40p heads, shorty headers and the k& n intake setup , my truck is a 4x4 supercab short box with 3.73 gears and turning 305/65/16 lt's .

 

the temp replacement engine is a 89 351 with the e7te heads. the performer intake, the 1.7 roller rockers the headers, and a comp 35-231-3 . I cant say how that one runs yet

 

to add a little more fire to the story my truck, when it was running right, my coworkers 99ish z3 convertible could barley keep up with the truck

 

I really wouldn't worry about the cam if the truck runs fine. If takes off without ******* it until it gets up on the revs, it's fine.

 

i rather have the new cam, whats $ 120 bucks anyhow?
