I have an all MSD setup on a '79 Bronco w/a 351M/400. I live in Alaska. I can drive from Glennallen (5000+ ft. above sea level) to the Anchorage basin (102 ft.). From the coldest winters to muggy humid Fairbanks (446 ft.) mornings in summer, it never sputters or falters. Love it.

You've done a really nice job on that engine bay and car overall

So I've got a good size cam in my 350sbc in a 1991 s10. I've dialed the Holley carb in to the point where I genuinely don't believe EFI would make me much happier drivabilty wise. Truck fires up at the tap of the key at 4am (at sea level down here in Hawaii) and again at 4pm after work. Daily driven street engine making an honest 350hp. Now I have the advantage of having worked in a speedshop for a good decade when I was a bit younger and learned lots from old gearheads. I feel like going to EFI on these older engines is like giving up. There is no reason you can't dial in the carb to perfection! That being said, I still have my eye on this kit for other projects and your review was precisely what I was looking for. Thank you very much for that. Your Camaro is beautiful 😍

I got fuel injection 20 years ago the first gen pro flow. Good system a little outdated and hard to find parts for but still runs good. For those that say you can tune a carb just as good well you can with an O2 sensor I've done it plenty times. Only issue is the tune changes with temperature and starting cold will never be as good as FI. This system looks good the price isn't bad and you can control timing with the 6A. I would look hard at this if I can no longer maintain my system.

Agree!! I hid the box under the rear of the air filter... Stealth.

I just has an Atomic EFI installed on my 1979 Chevy C10, stepside. I had to take it back to my mechanic because having duel fuel tanks made the installation process more complicated. I got my truck back two weeks ago and I am really happy with the EFI system. My carburetor was giving me trouble and I was looking at getting one that was rebuilt. That means getting a carburetor that has been in someone else's' car for the past thirty years. Also, my carb was dripping gas after I'd run it filling my garage with the smell of fuel and making my wife as nervous as a long tailed cat in a room full of rocking chairs. Worse yet my truck would sometimes just die in the middle of an intersection when I'd start out from a stop. I also had to pump my accelerator several times to start it when cold. Now, I don't touch the accelerator, I just turn the key and it starts right up, just like normal folks. And it doesn't stall in intersections. It's very embarrassing when you have a beautiful truck and it just conks out. Also, there is absolutely no smell of gas when I park it in the garage and my wife does not worry about the house burning down. It may be a little early to say but it looks like I'm getting better gas millage. I can drive up a mountain at high altitude and there's no need for adjustments. The computer makes all the adjustments needed all the time. Other new carbs were not an option for me as they are not street legal in California except in really old cars that don't need to be smogged. I'm really happy with my Atomic EFI, it performs flawlessly. A carb may have more power but I don't race my truck, it's a show truck really not a race truck. And, it has plenty of power in that 8 cylinder, 350 engine. Way more than I need. I can burn rubber anytime. I'm sure glad this EFI system came along and that it fits my truck. I'm as happy as a fat rat in a cheese factory.

I’ve got a 77 Grand Prix with a 350 and an edelbrock 650. It does run fairly well but there is times that it sputters and bogs no matter how well it’s tuned. EFI is coming in the near future for sure

I'm thinking of making the switch to EFI myself. The car doesn't like running in temperatures above 80° and after adjusting the carburetor the last two summers and two trips to the mechanic shop with no results, that was $900 down the drain. In my town we're out of the good old boys that know how to work on carburetors so that makes it more difficult. Thanks for the video and review.

Great review Thanks !!!!! I'm running a pretty decent fuel system, Aeromotive A1000 etc and a Quickfuel blower carb I think this is the brand I would consider

I recently installed the same system on my heavy street cam 302 in a 69 MGB. Previously had an eddlebrock carb. The carb was super simple to set up and tune for great power. The issue was on hot days vs cool nights. I could tune the carb for kick in the back power on those cool nights but then would be boggy on those hot Saturday drives. I could tune for the hot days just fine too but it sucks knowing your leaving at least 40 hp on the table when day turned to night. The atomic solves all that. Great power with out the frustrating hot days bog. Yes I feel the carb ultimately made better power on the cool days but the efi is better 80% of the time. Atomic system needs time to learn and internet help is frustrating. If you can understand what the adjustments values represent than it becomes much easier. Also diddo on the fan!

Do aftermarket EFI's work well on big cubic inch engines like the 565 or 572 BBC?

I put together a system for Ford 351W van and for SBC sixties Chevelle based on GM TBI EFI for a total expenditure less than $100 for parts for each. I performed the labor myself.

Nice car, Nice EFI System!!!

Great video

There are people in this comment section that know that it's possible to tune a carburetor perfectly. What they don't seem to know is that tune won't last through a day of driving. As the day progresses and atmospheric conditions change, air density changes too and carburetors don't self adjust to compensate. Now consider air density differences between summer and winter. Yes! you can tune a carburetor perfectly. How many times a day are you going to tune it to keep it perfectly tuned? Fuel injection tunes itself on the fly.

Nice video thanks. I just got my 68 Cutlass 350 back from extensive mechanical upgrades including engine rebuild, new carb, exhaust, etc. I'm disappointed in how it runs after spending a small fortune on this project. Runs rough and smells awful. I'm wondering if changing to this EFI system will solve the rough run and smell issues. We use this for a family fun car and can't deal with the smell. Plus, we wish to use it in parades and don't want people hating us.

Nice swallow sound right at the beginning

Thanks!

Nicely done. What did labor run you? Who makes that accessory drive system, clean. AED makes a fantastic carb tailored to your exact build fwiw. If you arent a wrencher efi is the way to go. This Ca ethanol gas sucks, fuel boils at too low of temps Love the Camaro stance is spot on

what kind of electric fans are you running?

That is a really great upgrade. I wish MSD would make them for foreign cars too.

I have this complete set up on my sbc it runs and idles perfect but on top in it sluggish and I don’t feel the power I should ... any advice out there

Sweet car!

i had a holley avenger 770 and couldn't get it run properly i purchased a MSD Atomic EFI and it runs fab now very happy whth it

Damn we have an almost identical situation. I recently bought a 69 Camaro ss too with carburetor and it’s been a pain, running rich and stalling. I’m seriously considering EFI and have been shopping around. I also have an MSD ignition system. Did you compare MSD to Holley and Fitech brands before deciding? My engine has 700hp capacity. Would this still be a good fit? Thanks for posting man. Get back to me if you can offer some advice Camaros rock🤙🏼

I have a 69 Camaro with 383 stroker and msd ignition setup too. I installed same msd fuel injection conversion on my car. Could you tell me what settings work best for you so I can see if it works for me. I would greatly appreciate it. Thanks

I really would like to go efi with the msd.But what bothers me all the time is the look of the system with all the wires visible.In this case the Holley terminator stealth is better but I've heard that the Holleys have much more problems and the support is a real disaster

Great video Mel, thank you. I'm interested in installing the MSD Atomic fuel injection system in my 1979 Chevy C10 truck but I want to determine if it is street legal. I still have to have my truck smog checked. Do you know how I can determine if the system is street legal. I called a California agency and they told me the vendor should know. I'm not so sure about that. Also, were you happy with the job MT did? I live in Orange County so I would give them consideration for my job. Any info would be greatly appreciated.

2:28 your throttle cable housing moving you should have a bracket to hold it so just the cable inside moves.

This guy was eithet paid off or the only guy running a MSD ATOMIC without issues!!!

Where did you purchase your Atomic EFI Air Cleaner

Do not mount the pump outside the tank, it has to be inside the tank, do not run a returnless fuel system, the engine needs a return system. Also, just go with the one fuel filter. I had to have mine done all over again. I live in Florida, so I don't know if that made a difference. But I had a regular mechanic install it the first time. I later had to take it to Detroit Muscle and they had to change everything. Also, buy your fuel pump separately. Get a high quality fuel pump, do not get the one from MSD that comes with the system.

How is it going for you now? I have the same kit I’ll be installing soon.

Yeah, but do you like it?

What kind of pulley system did you use, I like the look of it.

Great review. Did you experience any improvement in gas mileage?

Do you know who makes those hood hinges you have?

Are you still happy with the MSD set up? Still running the same fuel system?

Is your intake manifold a single plane or dual plane?

How has it been after 4 years? Still worth it? Im thinking of upgrading from my avs2.

Have you had any issues with it? Thanks.

So it's Feb 2021 now. How is it

I can't wait until they have something like that for motorcycles. There are so many old UJMs and 4 cyl super bikes which would go from nuisance to wonderful with a kit like that.

"Because of environment... and temperature that I live in", what do you mean by that? Dry Hot Summer? Or Wet Humid Summer?

Any vacuum ports?

What kind of cutouts do you have and who installed them?

That external fuel pump was a smart move!!!

How Much is this kit. ???

I bet 99.9 percent of the people in this comment section daily drivers are fuel injection. If its so did bad and your worried about being stranded turn you cars carb and see how you like it. I have had plenty of cars with carbs and my race car is carb. Can you set a carb to be perfect all year round? No. Will it run ? Yes but it won’t be optimum. Have a motor with a big cam and try and start it and go. It ain’t happening. On a race car it doesn’t matter cause your basically tuning for wide open throttle. But on a street car or hotrod fuel injection is where it’s at. No pumping the throttle, keeping your foot on the gas to idle till it’s warmed up. I did 2 systems on my buddies cars a fitech 600 and a edlebtock e street. Both work wonderful and they love it. Don’t bash it till you have experience with these systems.

Not even NASCAR uses carburetors anymore. It’s called progress.

The computer doesn't talk to the fuel pump lol. It pulse modulates the voltage depending on demand.

Although all of these are nothing but updated t.b.i .i would stick and .....LEARN.... How and why a carb works. My t/a 1050 carb, my z28 lt1 sfi . Yes efi is the way to go but it's just t.b.i with only a few of the sensors of an all out f.i car has. Crank sensor,map,Maf, I.a.c etc

سلام عليكم ILOVE CARBURETOR IDONT LIKE EFI OR COMPUTER TO DRIVE MY ENGINE CARBURETOR MORE POWER NEVER FAIL

It's not hard at all to dial in a carburetor. Im not sure there can be any more simple device than a holley carb.

ill take ur old carb

I hate the sound wen the video starts

All of this is good until you break down on the road in the middle of the night. I'll keep my carb.

For someone who says that this isn’t an advertisement, it sure sounds like one.

Id leave the carb on the engine it came with it was set up for the engine that efi might be making your engine lose power plus if you by a car like that you should know how to tune it

if you ever think about selling that car, you let me know

I bought the Atomic for my Ls 3 and runs like shit ,no matter what I do it burns raw ,its been junk ,the FAST efi works a lot better

lt does NOT come with everything you need. You still need to buy a CD ignition box. lt won't run without one.

Did he seriously say nothing on this car is original??🤣😂

Cool system, but its really not that hard to set up a carb. You have to use a vaccum guage first to know what power valves to use before you start jetting. A out of the box holley dp carb when jetted properly is only 2hp lower than your injection system and it was done on Engine masters dyno on youtube. So you still have a lot of power left in it when you have your carb sent out for work done if you want more power for race applications. The vortec engine has a plastic factory truck manifold that no aftermarket manufacturer has been able to make more power from 0 to 5500 RPMs. Then the aftermarkets edge them out above 5500. So unless you are racing high rpms, guys are wasting thousands of dollars.

Too bad you wadted your money. Fi tech is cheaper and easier to hook up.

Come on guys carburetors belong in the stone age

You start off with a beautiful classic car and you change this and change that and you end up taking all the things that make the car beautiful. I hate seeing this at car shows. It just not the same. I have 5 classic cars. A 1968 chevelle 396. A 1969 convertible Firebird 400 4spd. A 1978 Trans am 400 4spd. A 1987 Buick Grand National. And a 1959 Chevy Apche. I will not change anything. It takes away from the car.

EFI=People who can't tune a carb. Get a carb dialed in it's just as good,...for less than half the money.
