Novice EFI install

I have procrastinated long enough. Tomorrow I will begin the tear down of my current carb set up which is running the best it has ever ran since I installed my Mark Jones 496. We are finally getting some summer so this is not helping. I am enjoying cruising. I will work some evening to try to get this conversion done before winter flies. I will go nuts if I can't try it out before the snow comes.
Any way I consider myself a novice and an absolute newby when it comes to efi.I will try to update this as my install progresses. It will be a Holley HP efi sequential mpfi system. I have most of the pieces to start so lets see how it goes. I am counting on you guys to help me out.

Here goes...

I have port matched the intake to the gaskets.The Edelbrock oval port intake was originally 1.7 X 1.9. I have bored it out to 1.9 x2.1. The bit kept loading up, It took more time to clean the bit then grind the intake!
I have modified the throttle linkage and fuel rail for clearance. I needed to add a spacer under the throttle body and trim some material off of the fuel rail. The linkage got turned inside out and I built a new piece of the linkage to square things up. Powder coated the intake and rails.(I wasn't planning that but they were rough and it help hide my grinding on the rail).I have installed a good chuck of s.s. 1/2 hard line beside my 3/8 existing line that will become my return. Built a mount for my ecu that will be in the engine bay.
I will go for one last ride tomorrow if the weather permits and start draining fluid tomorrow nite.
Pic 1 is what I am starting with.
pic 2 the new linkage piece I built. I only had hand tools. Guess which piece I built !
3 I am trying to show the clearance I have
The rest are pics I like.

I am handy but remember I am a NOVICE. If you see this project going south let me know!

Re: Novice EFI install

There's always going to be some modding/grinding getting these things installed, especially under a stock hood. I wonder if in the the end, I should of ran the Victor intake like you did rather than the Holley, as the Holley intake is very high. I did get the thing under the hood afterall.

Keep at it - you will be VERY happy once she's up and running.

PS - how about bending-up some metal tubing (like Holley does) for the end rail connections rather than have all the hose?

Re: Novice EFI install

I have some left over s.s 1/2 tubing, I'll see what I have for 3/8's tubing and fittings. My 10 dollar bender might not be up to the task!
I enjoy modding. I expect it on anything I buy aftermarket.

I am counting on you Vince to get me through this!

Re: Novice EFI install

Hi Dan, looks like a fun project!
Hope you don't mind if I keep an eye too?
This is the "NEW" holley system, right? Not the old commander 950?
I been dieing to see one in action, half tempted to convert mine...

Re: Novice EFI install

I am going to do a Holley HP MPFI on my 427ci 550hp SBC. I am looking to use LS1 coils and use a 60-2 crank trigger and a vortec cam signal distributor with a flat cap on it, so I ca run sequential.
Keep us posted

Re: Novice EFI install

Not much to report .
Installed the ecu (yep the new Holley) on to my shaker. It now has another use other then being a boat anchor.
Finished welding up the lower air filter housing so it will clear the linkage. I glued a 4150 flange to the 4500 filter housing. The housing has to be clocked with the linkage to work.
Tweaked the mounts to get my coil to sit on the manifold. I am a little concerned about electrical noise as there will be a lot wires in that area.
I will pull the fuel tank out tonite and maybe the seats so I can run some wiring later under the carpet to the back where my battery and msd box are.

Riley, are you going to use the "vortec" distributor for later model motors? Is that a drop-in deal? Just wondering how that gets hooked-up, and the coil.

There is a harness from holley p/n 558-410 that I am told will plug into the HP EFI harness and has a crank trigger sensor end on it and a cam sensor end that plugs into the vortec cam sync plug on the GM dist. There is a vortec cam sensor distributor "plug" that only has the sensor and oil drive with out a rotor or cap that is better looking if one is to use DIS instead of a single coil and distributor like I am. The LS1 coils will use a holley harness # 558-301 that plugs into the HP EFI and will plug into the LS1 coil harness on the other end. Holley does offer a DIS system but it a waste fire and I didn't want to run the opposing cyl plug wires across the motor.

Re: Novice EFI install

I got a few things done. New fuel tank is in and the fuel lines are done except for two short line to and from the fuel rails. Wired in the new fuel pump and run some wires from the battery in the back to the firewall for the main power for the ecu, fuel pump relay and points wire for the MSD. Added a few more wires to the main harness including a usb cable. Out came the fuel pressure gauge and Dakota digital fan control. The fuel pressure will be bit higher now and the computer will control the fans.I am leaving in my afr gauge for now. I will compare it to the Holley wideband on the other side. Pulled off the old manifold and started prepping it for the new one I hope to throw on tomorrow. I'll try to get the harness installed as well if I get time.
Couple of shots of the new tank, some plumbing including a vent filter and new hard line, completed wiring harness and gutted engine bay.

Re: Novice EFI install

Got up early and got the intake on before parenting and work took over. Seemed like it went pretty straight forward. All the bolts fell in pretty easy. It was my first time changing a manifold so it was a little stressful. No leaks I hope. I got a hour or so in tonight installing the wiring harness. I have it half tore apart now as nothing fit the way I was planning it to. I imagine another hour or so and I will have it routed better and cleaned up. It is getting very tight back there now. On a positive note the throttle linkage bolted right up and works very well. The air filter also fits fine. I think another 3,4 hours of wiring ,a hour for a fuel line and hour to add/change fluids I should be getting close. I got a computer geek to fix up my ol laptop yesterday and got it back tonight. It seems to have perked right up so hopefully it will do the trick when start up comes around.

Looks good Dan. Where did those fuel rails come from? Sexy for sure. When your ready to fire it up, just download the closet fuel/ign map and it will run excellent right from the get go. Only thing you will need to do is add timing for your cruise rpm (to sim vac advance) and tweak the idle AFR/ign and your good!!!

Re: Novice EFI install

DONE!
I have all the wiring completed, fuel lines are finished.Changed oil,put antifreeze back in and dumped 10 gallons of fuel in the new tank. I have a little tiding up to do but not bad. I will reread the start up instructions tonight and read up on this FAST distributor. I'm a little lost where to set it or how. I dont think I will turn the key tomorrow as it is Thanksgiving and we are invited out. I need another set of eyes and hands also to look for fuel leaks and check timing as it gets turned over.
Now I need to get ready to trouble shoot and put my basic computer skills to the test.

Vince, Edlebrock fuel rails turned inside out.

Re: Novice EFI install

Nothing exciting to report. Keyed the system up without the injectors hooked up. Found 2 fuel leaks. One was in one of those spots you prey it wouldn't be. Anyway it is all fixed up. I am now waiting for help. A second set of eyes to check timing when I turn it over and double check leaks.Down loaded the base global folder into the ecu. All my sensors seem to be up and running. Did a throttle position autoset.
I am finding the instructions for the FAST distributor a little confusing. Hopefully tomorrow night I will make noise.

Re: Novice EFI install

Finally was able to get back at it late this afternoon.I was ready to turn the key and was waiting for help so someone could verify cranking timing. Well we spun it over and over.....nothing no spark.
I verified I have spark going into the distributor but nothing coming out. I am running the FAST dual sync. I was scared of the ignition before I started and here it has bit me already.
Any ideas on the problem?

Re: Novice EFI install

Hey Dan,
This is really the only part of the installation that is a little tricky. The FAST dist comes set up for a 50 degree crank reference angle. Make sure that the setting in your software is at 50 degrees. Disconnect the coil!!! Then set your number one cylinder to 50 degrees BTDC on the compression stroke. Line the rotor up with the #1 terminal on the cap and install the dist. The Dist comes with a red wire for power to the dist. This should be on a circuit that is hot in the start and run positions of the key. There are two LEDs that will light up on the dist, One for cam signal and one crank signal. The cam signal is on the left and the crank signal is on the right. With power to the dist, rotate the base back and forth until the cam signal LED lights. Now rotate the dist counter-clockwise until the first crank signal lights the crank LED. Rotate the dist back and forth to find the leading edge of the signal. Tighten down the dist. The light should flicker as you move the dist back and forth. Put everything back together and start the car. Check your timing to the timing tables in your software just to make sure. Tip: temp set your timing in the idle area of your table to a constant number so that it doesn't jump around when you are checking it. Pretty easy, just a little confusing.
