I have a 2003 GT i want to put the 347 out of my 84' into. i believe i will run into issues with the brake booster. I already know ill need a new K member and ive located one from AFCO. I need to know if all i need to do is re-route the vacuum from the hub to the intake on the 347? Any ideas folks? Thanks

Brooks,
The vaccum for your brake booster can be run off of the intake. The 2003 brake booster is also a hydroboost until and will need the hydraulic lines plumbed to the boost unit from the power steering pump. You might want to take a look into how the 5.0 in the 95 Mustang was run. Good Luck!
