3.0 Updates. and new questions

[88workcar]

I have read through all I could find here and other places. I have a 2001 3.0 single cab. That engine will not stay in there but it will be a little while. While working towards my project I find myself wanting to do things to the 3.0.

1st question, has anyone used the Tom Morana parts? Ported intake, dual TB mod and so on? The dual TB intake claims 25hp 25tq. I think that is quite far fetched and would like to know if anyone has indeed try such parts.

I have been porting intakes and heads for 20+ years and this would be nothing to do. I do have a broken exhaust stud on one head so I will be pulling them. I will order the reman heads with the upgraded seats ($309.00) and port those, then swap.

2nd Question is are the old 5.0 Mustang rockers interchangeable? I have a few sets.

I know the engine was designed for torque and it does well, fighting the shear design could become a issue but i'm not asking for this one to see 200+ and 6k rpm lol. Just put some pep in it's step. Thanks, Jason.

I believe people have used the roller rockers and had some good results. As for the ported intake and stuff, I'm new to the Ford Ranger, so not sure if I'm correct or not in my assumptions...

I think some of the stuff he has is for the 3.0 is for the older 3.0 where it had the non-composite intake manifold. Then there's stuff like the "large elbow throttle body" and "4 barrel carb'd intake". I tried youtubing some of the stuff he has listed to see what it does and stuff like that but was not able to find much on some stuff.

He also has 2 different 60mm throttle bodies listed. One for 270 and one for 300. I'm honestly not sure what the difference is. Would you have to port the intake manifold to make it work? If so... the 53 mm should be a bolt on? BBK used to have the BBK 1902 which was a 56 mm throttle body for the 3.0. Can't seem to find one now.

I believe Tom Morana is one of the only people that makes stuff for the 3.0 though.

Here's a couple links to what someone had put together:

I've got Morana's ARP head studs, upgraded valve springs and 1.8 roller rockers. No complaints. Not sure I'd spend the money/do the work to make one of the intake manifolds work unless you really wanted an "all motor" NA 3.0.

There's a bunch of material in the lower intake manifold that can come out and be opened up to match the ports on the heads/upper intake better:

Just wanted to post some before and after pics incase anyone was interested. I gasket matched the ports as deep as I could, and focused on smoothing and straightening the truns as much as I could. I took some measurements, and the round intake ports were increasaed in area 15%, while the...

Heads have plenty of areas for improvement too. Some go more hog wild than others. Here's my "medium" amateur port job:

Looks great! I'm not really big on lowered trucks, unless its a lightning lol. BUT I like it. Love the heat extractor hood. Good luck on the engine work

Those were the first things I ever ported, so they were a learning experience. I'm not embarassed by them, but I could've done a better job too.

Thanks guys, I have ported several 5.0 intakes with great success. I think I will start there. Flow all of the intake 1st. Does anyone make a long tube header for us?

'Course I was always told "there is no replacement for displacement."

Just wish Colorado emissions would allow me to do the 5.0L V-8 swap.

Nope.
