Is it worth changing your stock throttle body 68mm to a 70mm do you get that much more power ?
also I have a 05 4.0 I have installed heeders and cold air induction does it make sense to go further ?
for a small block
More power and how far to go with modifications is a pretty subjective subject.
I doubt you will notice a difference between 68mm and 70mm tbs.
I'm not that familiar with the 4.0 engine but it seems there is a little bit of aftermarket support but mostly in the turbo arena, that may be the way to go. Ask around in the 05 V6 forums for more imput.
And welcome to stangnet.
Hello from Salt Lake City!
I have a 1968 convertible That my dad purchased for me when I was 14 years old, I am 53 now, so I've had it for awhile, lol.
I was born and raised in the Seattle area, moved to Salt Lake City 6 years ago.
originally the Mustang was painted gulfstream aqua, and arrived to our garage with some minor front end damage. My dad and I fixed the damage and painted it red, I then cruised around in it until my early 20s, before completely dismantling it in 1989.
fast forward 30 years, I am finally putting it back together. In the early 90s, I built a rotisserie, and painted the shell Vermillion red.
I have not done anything to this mustang until last year when I started the assembly process.
I am looking forward to tapping into the resources and knowledge all of you experienced Mustang gurus during this tedious process.
here are some pics of where I am with the assembly.
