I have done some research using the search function however I did not see anything that answers my question. I am collecting the parts necessary to do an Eaton swap on my '03 Supercrew. My question is in regards to the harmonic balancer that I will need for the swap. I have the lower caged pulley assembly for a 99-00, it came with a flange that appears it would bolt onto a balancer and allow the caged pulley to thread on. I did a search on the White Bear (formerly Tousley) website for the Ford number on the 01-03 Lightning stock balancer and its the same number as the NA balancer. Will that flange bolt to my OE balancer? If not, is there any reason that an 03/04 Cobra balancer would not work? I have a nice low mileage version that looks like would allow me to eliminate the flange entirely. Both my truck and the 03/04 use a 6 rib inner belt so that is not an issue.

I understand the 99-00 and the 01-up have some differences. I am curious what my best option is?

The 3 bolt flange pattern is the same. My truck is also an '03 with the 6 rib belt. If you have the caged lower with the bolt on style inner hub it will be fine. I put an aftermarket 4lb lower pulley set up for a lightning on my truck and it bolted up just fine. It may be a route to consider unless you want the stock size lower.

Get a metco hub and run a stock size pulley that way it's easier to up the boost when your ready

That's good to know about the flange bolting up, that will make things easier. I'm not looking for much over stock boost, I'm going to put a JLT on it otherwise it will be stock. I picked up a brand new in the crate oe Ford '00 supercharger/intake assembly, it came with the new lower cage/flange, alternator, and a pulley bridge set up. I picked up rails, 39lb injectors, MAF, and an 03/04 Cobra stock H/E. I have some of the Cobra plumbing and IC pump left over from other Cobra projects. I still need a plenum and TB, alternator bracket, some of the vacuum lines, and some wiring/sensors to complete it. Not trying to set the world on fire just need some more daily power and towing grunt.

Your going to want to get some stock L fuel injectors which are 42lbers. And dont forget either a Lightning fuel hat which is for 2 pumps or just a single higher capacity fuel pump. I do have a pair of stock pumps, if you need them let me know.:smt023:rockon_ford

Thanks for the reminder, I was planning to stick a 255 or 340lph in the tank. I am using a set of 39lbers out of an 03/04 Cobra and a stock 90mm Cobra MAF those should be sufficient for what I am looking at power wise. It is going to be a spring project, I am trying to get everything I need beforehand.
