Good Morning All,
First post here so I thought I would show what I am working on over the last month or so. I have a 66 Charger with a 440 (originally 318) that I am converting from a Holley Carb to the Edelbrock Pro Flow 4 XT system. As with any project, it always turns out much bigger than expected. The engine bay was in need of a serious clean up as well as the engine. Engine came out and both the engine bay and motor received some new paint. Along with some new seals to stop a few oil leaks.
Before engine pull and paint. Edelbrock intake set on to test hood clearance.
The mess I was making:
Engine after some love (old intake was put back on to hoist into car)
Motor is back in the car and I'm currently working through getting the new fuel lines in the car. So far I would say install has been fairly straight forward. Below are the major items I purchased and for the most part things seem to be falling in place. I checked hood clearance of the new system on the engine before I pulled everything apart and I believe I have more room with the XT system than I did with the Holley Carb and an air cleaner on top.
Engine bay with a fresh coat:
Engine back in car:

I expect I am roughly a week or two out from attempting to start for the first time. One hard lesson I learned is "buy the dang tool that compresses push lock fittings onto rubber fuel lines." I think I tore my bicep trying to get those on the not so clever way. The $300 tool is going to be looking mighty nice after my doctor visit next week.
One of the tougher solutions I thought should have been simple was to find a way to route the return line back into the fuel tank. I did find a solution on Summit and it should be linked above. But I still don't love the setup. I figured a 5/16 inch bulkhead barb fitting would not be all that difficult to find. I ordered 3 different fittings I thought would work, but when they arrived, the fittings were indeed 5/16 but the bulkhead washers and nuts where way to big for the location I wanted to place them. Thinking back I should have just had a 5/16 tube welded into the tank. But we'll see how the return line going to the filler neck works. It had great reviews on Summit and if I hadn't cut the neck off incorrectly to start with. It wouldn't have been a tough install.
A few items I'm still thinking thru are the intake elbow and if I want to move my battery to the trunk (of course I do, its just a question of do I want to do it now). I do not have electric fans on this car so the gap between my radiator fan and intake is not large. I ordered a cobra head intake elbow to see how it works for now. But once I decide what to do with the battery. I'd like to have a custom intake tube fabricated that would put air cleaners on each side of the engine bay. I thought that would look pretty clean and I thought the symmetry in the engine bay would be cool. I'd also need to figure out what to do with the upper radiator hose as it would be in the way as well. So for now, hopefully the cobra intake will get me started.
I'll continue to post pictures and thoughts as we progress. I still have some wiring to clean up and need to finish the fuel line connections. But we are nearly there. Obviously the major item here will be the tuning side and if I feel this was all worth it. I'll make sure to include the specs on the motor as well when I get into tuning so you all can compare to your engines. I really struggled with tuning a carb (and carbs, had two 4 barrels on it at one point) over the years so hopefully this helps.
Hope everyone is having a great year so far and looking forward to car shows this summer.
