  • The folks at Holley Performance Products were kind enough to send us a Terminator EFI, which we recently installed in Hagerty Parts Finder Davin Reckow's classic Chevelle. We test the impact on performance via the "butt dyno," the 1/8th-mile drag strip, the chassis dyno and gas mileage. Subscribe! | bit.ly/1sddOmD

    Chevy made some beautiful cars back in the day and certainly this '66 Chevelle is a representative of good design. This '66 is one of my favorite for it's style and looks alone and like the Chevelles from that era, definitely a hit for that big block 396. That EFI is amazing too!

    As usual some of you are missing the point of this. It wasn't to make more power, that was just a bonus. It starts better, has better driving manners, and gets better economy. If that's not what your looking for don't buy it, hell it's your money. I liked the video even though I don't plan on ever owning a carb'd vehicle again.

      Whatever power your making with a carb, you could be making more power with EFI, his power level has nothing to do with EFI and everything to do with his intake, heads, cam and compression. It made 500ft-lb of torque at the wheels though, and that's excellent for what it has.

    I was sick of pulling fuel bowls off constantly to make adjustments to fine tune the balance of street driving to WOT and having to make compromises to achieve the performance and streetability I was looking for. That was what pushed me into making this conversion. Running these systems also allows you to upgrade to a single plane manifold, in fact they even recommend having a common plenum for a more accurate vacuum signal to the MAP sensor. The wiring is easy, I used only a couple wires for the optional items while the rest is self contained so definitely do not be intimidated by that. The part of the install that took the longest was just the figuring out the routing of the harness to best hide it and cleanly integrating it into the factory harness. I chose a completely different route for fueling than an in-tank pump since I do have a return line but my tank has no baffling and could still suck air in certain situations with a less-than-full fuel level. Still have yet to drive it but I have started it and my goodness it was easy and the smell of vaporized fuel was no longer filling the garage after running it. I can’t wait to get it out on the road.

    Hey guys, great to see you doing another series. I've been a qualified mechanic in Australia for 15 - 16 years now and am a qualified LPG installer/ LPG RWC Inspector (LPG cars in Aust require a separate RWC for their LPG system itself) and RWC (Road Worthy Certificate) Inspector amongst other things and thought I'd chime in on the fuel tank issue. Firstly, I would NEVER recommend anyone doing their own welding on their car's fuel tank at home in their garages- BUT FYI- it's all about purging the tank clean of flammable gasses obviously. One method old timers used to use was to completely fill the tank with water to push all the air out and then go about cleaning and drying the tank prior to commencing welding but these days we use an inert gas to purge the tank clean thoroughly, then clean for welding. THIS IS NOT A JOB FOR THE HOME MECHANIC, NO MATTER HOW EXPERIENCED. THIS IS A WORKSHOP ONLY REPAIR, IN MOST PLACES MANDATED BY LAW.

    As someone who daily drives an 84 pickup that's carbureted I was seriously thinking about buying the Holly EFI kit, even had it in my shopping cart on Summit ready to buy, until I dug a little deeper. The pros are obviously mentioned everywhere: Tunes while you drive for maximum fuel economy and efficiency, better cold start up, no more having to deal with my manual choke, etc etc. But what they don't tell you is the cons. This is not an easy job that you can throw together. One thing they don't mention is you need to have a single plane intake manifold, or you need to cut and notch out your duel plane intake manifold, otherwise the Holly EFI will never run right. Duel planes are way more common, so you'd have to pull your intake manifold off and cut out and notch it and then put it back together. You can even see it in the HolyPerformance install video (even though they don't mention it). If you're half way into this project and didn't know that you'd be pretty pissed. And then there's the kicker, a properly tuned carb will run better and make MORE power than a Holly EFI kit. Holly even admits to this. So unless you're still in the build process or you have another vehicle to drive while you try to install this kit I would not recommend it. Go with a $150 wideband gauge and tune your existing carb. Hell I even added a $25 dollar flow through electric pump so when I let my truck sit for awhile I can prime the carb and it fires right up no problem

      I had a 1986 k-5 blazer with the stock 350. It had a bad accelerator pump and a dead cylinder but no matter how long it sat you could bump the key and it fired right up. You’d have to feather the gas when you moved from a stop to get it to not stall but the thing would just fire right up and it would never leave me stranded. I miss that thing.

      @jfv65 7 ปีที่แล้ว +13

      you can tune a carb all you want but in the end you can only put 1 static tune on a carbed motor whereas EFi learns and tunes the engine all the time while driving. Think about low vs. high ambient temps or low altitude vs. high altitude, clean vs. dirty airfilter. These variations will all be tuned out by the EFi.
      EFi also does it's own cold start enrichment, no choke needed.
      EFi is also able to cut off fuel when engine braking. It also controls idle speed dynamicaly (compensating for AC, alternator load, powwersteeringpump load.)
      once you go EFi you won''t look back.

      Kills me how many guys try to tune there carb off of smelling the exhaust pipes for a rich or lean mixture.
      Maybe a trained blood hound could do that but no human is gonna know AFR from smelling the exhaust.

      Carbs are a good way to make your engine run. Very primitive, but effective. However, EFI has so many benefits over a carb and unless you play with one, you will not even begin to understand. Besides, big oil companies are forcing you to convert with the fuel they supply...

    • @cuzz63
      @cuzz63 2 ปีที่แล้ว

      I have seen a few with issues but most of them come down to improper install, usually wiring. Old school car guys think they can get away with janky wiring, which doesnt work with EFI. A well tuned carb is great but constant tuning for todays gas and conditions can be a hassle.

    The only EFI kit id consider now a days is the FiTech GoEfi. Starts at $795.00 and you dont have to modify anything. ECU is self contained in the throttle body with the injectors. Comparing Fitech with Holley makes the Terminator look like an antique.

    Great article. As far as I last read (which is admittedly a number of years back) even the best EFI retrofit systems still made a few less HP than a properly tuned carbureted engine. I'm merely curious from a dollar for dollar standpoint how close the Chevelle could have come in terms of power and perhaps even mileage with more intensive tuning of the ignition and fuel systems to begin with.
    That being said, besides the other advantages listed on the video I can really see a great improvement on plug life, especially at idle, and ease of starting every so often in Winter months.
    Nicely done.

    • @GlassTopRX7
      @GlassTopRX7 8 ปีที่แล้ว +5

      +Tory S The EFI will make more power, in most cases it wont be dramatically more though. The throttle body doesn't have the restriction and turbulence that carb jets induce at least with the current kits. Granted we are talking about a throttle body system, the it's not a huge leap really. Even if they were rated at the same CFM the throttle body would still hold an advantage because of the turbulence. MT just posted a more detailed dyno comparison using a LS motor and they had the carb jetted and couldn't match the EFI.

It's just intended to get you to buy the EFI setup. They don't care whether you argue in the comments - it just increases exposure of the video in the youtube system.

    I did a conversion myself last year for my 64 Comet, though with a different system, but with similar results. Amazing drivability, with much smoother torque and more of it in the lower RPMs, smoother idle (have a fairly large cam), and surprising gas mileage increase. My biggest issue is controlling fuel slosh when tank is below 1/4. Carburetors have a built in reservoir (fuel bowls), so aren't affected by lateral or forward G's as much, but the high fuel demands can cause a lean condition due to fuel moving away from the pickup. Did you find similar issues? And if so, how did you address it?

    • @torys8236
      @torys8236 9 ปีที่แล้ว

    • @jbird4471
      @jbird4471 9 ปีที่แล้ว

      I actually, just this morning, added a large basket filter between my tank and external pump. I'm hoping this will give me some reserve, if the fuel does slosh away from the pickup under acceleration or corning when fuel levels are lower. If not, I'll probably go ahead and modify a new tank. No one seems to make a drop in tank for my specific car. This will be especially important when my blower goes in next week!

I do have a father and a family friend that are very savvy with old Chevys so it won't be as much of a chore for me- but you can easily find one that doesn't need as much to be "modern", or just drive it stock!

      Your right about your age group not having these sweet cars. As a matter of fact, young people are actually holding off buying cars these days.

Myself, if you add 20 to your age that's me, lol. So when I was almost 8 these were BRAND NEW! I suppose I never stopped loving this particular car since my cousin had one way back then. He'd take me out a lot in it. It was all black, all stock(w/ a few mods) I'll never forget the sound. Sounded like a jet engine! I figure if I don't get one soon, I'll probably die without ever having fulfilled this one dream. So I really don't know. I do have a garage to keep it dry in for starters.

If you have a 396/360 you have the high performance engine. IF you have the 396/375 you can tell it buy the intake manifold. It will look SILVER because it is ALUMINUM. NOW get a set of AIR BAGS for the REAR. The stock carboarator for a 396/360 does not put enought gas in the engine. YOU NEED a 780cc. If you have a 396/325 hp, that is not a high performance block. The 360 says hp on the BLOCK in the back. To make that car run you need a 4.10 rear. The rear will make the car go fast but it will cost you a lot in gas. My 396/360 came with a 331 rear. My best friend bought a 396/375 chevelle with a 4.10 rear and could not afford the gas. WE swapped rears and this made my car fast. There is a 396/375hp chevelle out they some where with my old rear in it.
