Would this combo work?

[Rynb15]

OK,im getting a 90 5.0 from my buddy in a couple day here. and i was looking at doing a few mods right away. What the car has right now is shorty headers,and some type of cam. Nothing to big but you can hear it. The car has been sold a few times in the last year so no specs on the cam. Im looking at getting the trick flow track heat manifold and a bigger throttle body. Im just wondering what kind of gains i would be looking at with out doing the heads. If its worth the money or to do something else. Right now the car will run 14.1 on bald tires. I just want to get it to the low 13s hopefully with the set up im talking about and some slicks. I know people are going to say do suspension work first, and i will just not yet. Also i am going to put on a offroad x pipe. Think it will get me there???

well if u get some good tires.. also i would get a 65mm TB untill u get some heads... 70mm might be overkill so i am told... I had a off road H pipe and then i went to a off road X UPR and droped me 3 tenths in the 1/4.. u might look at 25HP gain with a intake and TB also if u hook up u should be in the mid 13s easy!

what size is the stock throttle body?

 

[Nick302]

55mm or so.

 

[Rynb15]

if i did the manifold and the bigger throttle body would i need bigger injectors?

nope, you really wouldnt need injectors until you got into the heads.

Find out the cam specs. It is probably a Ford alphabet cam which r just OK. If u want a great H/C/I on a stock bottom end 5.0, go TFS track heat stage 2 head from summit, TFS Stage 2 cam, port matched RPM ll intake, Accufab 70mm TB, PMAS 75mm MAF, LT headers, SVO 3.73 gears.
