Carburetor vs Fuel Injection on a 541 HEMI - Dyno Tested 

im mechanically injected( racing only for me nowadays in diesels or meth/E85 and add a big-mag or twinsets ) or DI/port and add COP/CNP for me and my 69charger/4.3X4.5in D8 hemi + Tr6060/C7-dropout wasn't interested in computers as a teenager/pre25~yo but my zoomer sibling ( go figure there into Japanese/JDM's and viper's/copperhead-model and yes i also like the RX8 body-styling and TT/compounded 3-rotor 20B-engine ) helped changing my mind and i ended up working on OBD2 ~1997-08 vin's and i got to see vs my 87~era k1500 how much progress has been made in daily's-tunes ect, VVT was possible and done in limited models/aftermarket parts but adjusting a cable+driving ( in 1930~ ) is a pain and the holly( also makes carb's ) methodology ( 1950-70's~ ) of cintrificale-force/spring's isn't prefect but better than being fixed-setting same within the leaking-downward/upwards lifter's ( 1960's road's-LLC ? ) for VVL vs muti-air/computerised, still like my platform/hemi/906-iron and im not planning on leaving it for my car ( the hurricane L6 or 2L 4's don't have a place in my driveway for now the BEV/hybrid/fuel-cell is a maybe's ) but if i can im not aposted to modernising/upgrading-it as i see i wants

wifi and pad-charging is a double edged sword as it makes it easier for me/someone to tune/user-friendly ( and more choice's as carrying and or remembering connectors/dongle's can become a pain and in phones-the-most-likely/tablet's/less-so-laptop's im kinda surprises me that they aren't plug-free at this point, phones like iPhone/flip's are trying to pass IP68 testing and less opening's the easygoing it is to pass and or making a scuba divers models and or one that putting up with my car+millwright/ranching setting's ) at there kitchen table or inside there home or eating at a roadhouse/coffee shop ect but also now making easier to hacking and stealing or cop/others-blowing-up ect still a EFI advocates after owning carb's+dizzy's and diving from Florida* sea-denver co USA the carb just cannot keep up and my wife wasn't happy about my dirty shirt ect as for engine swapping nope not in my 67-71 charger it's keeping the big-bock K-sub framing just with a dry sump oiling and deeper-bread-pan style aka 9in SS 1868-mopar oil-pan looks my chevy C10 1968 ( sold and yes Denver run-vin/time 327+sm465 4:10 towing for a friend ) and or 1980's k1500 yeah okay time for hybrid or BEV swapping as the epa getting gumpy about me using a diesels or copying* my charger's setup

A carb is fine.......until it coughs and ruptures the diaphragm in the power valve, or it gets trash in the air bleeds, or you travel from sea level to 12,000ft, or it boils or vapor locks because today's gas is formulated to vaporize easily..... Before you say it, I'm a gray headed old fart that grew up with carbs and my hotrod has MPFI.

Thanks Mike. Glad you liked the vid.

Glad you enjoy it!

@@Karrpilot when you're done using it run it out of gas and your lawn mower works every season for me

When going into storage, fill tank with "clear" (aka non-ethanol) gas. Alternate: Aviation gas (blue). What 1st responders do with their power equipment.

What’s it weigh?

Don't chew on too many of your words because if you think about it, the intake design and centered 4 bbl vs 2 4 bbl spread equally over the length of the engine is not an accurate comparison.

We can’t help it.

personally for carbs i liked my 68 C10's cable's/Manuel-choke more vs my E-choke on 80's gm's/k1500, thermo on my( im millennial/zoomer generation fyi ) 1970~ 383-LD-BBC was a hit or miss experience for me and wish for EFI or cable's for carb and timing/dizzy, also not big on tapping as i generally don't get the best experience and let the coil saturated and start and mess with the choke/timing but modern 2015-upwards is way better if added correctly on aftermarket and in dealership's/OEM's, skip the 1970's-2002~ era of EFI/obd1 not constant and headaches of both thoughts processes

Also far less things to replace in the unlikely event of an EMP that would instantly kill most FI's currently in use. Yea, I am stretching it, but better to be ready than sorry.

Don't forget about a carburetor having way less things such as sensors, computers, wires, and injectors to screw up and leave you stranded on the side of the road as well.

no doubt be very pleased with the performance this elephant will give him i was team mechanical-inj+hot-mag no-boost/no NO2/or/on~871 as a teenager/pre-25yo ( millennial generation fyi ) but my current/next combo is a 4.3x4.5in stroke's iron D8/modern-repop hemi on TT-boost and EFI as iv heard im going to be more happy with it and it will be less fussy that my elder's/coworker's experience in the 1970-1990's era as OBD2 ect calms down the radical setup to be more street abel than even my ideal teen 572-wedges

i was about 14-to-27 and at part store ( older gent probably now in his 50-90's yo, different guy but about the same age and at a car show told me about his new-at-time 1971? cuda that one main street Ogden ut 1971/72-era spun the back/N8+N7 rod main's+burnished the rope seal ect from starvation full-8qt's/dealership's-delivered on hard-lunch 426/stock-setup and told me id better considering using a dry-sump systems to avoiding crying+cursing ect as it happened to him more than once in the 70's and herd similarly storyline's but the other's are 440's~ and or less-bad-ending's ie seal had to be replaced or one-rod/N8? ) and around Christmas time ( 25-45~ yo as i was the youngest one of the bunch around 2008~ era at 17-21yo-me ) in a meatpacker maintenance shop ( my side gig around 2008-14 was a NE/Lincoln* USA Chevy's/caddy's/DSM repair and or racing shop ) and got talking about cars and wifes/family and or they found out about my 383+727 60's charger and mentioned that they or there buddies car/pre-1975-challenger 833-stick ate plugs ( about every payday~ ) and wires ( and valve covers leaking 90-d-to-yearly and or rear-main but that's unfortunately commonplace for BBC in general worsening if driven-hard and or lacking maintenance like oil-changes ect, my plans currently for my new setup is converting into a new rubber+one-peace-unit and deleting the front seal+drive's and use top-fuel tricks like copper-spray/lacered-paint/felt/corke-gaskets and 1970 alcoa casting's instead of being stamped-covers ect ) regularly and the carb ( also-they tried different intake's to solving it and different types of carbs ect, didn't work but found out that the single-carb and single-plane and Mallory+CDI-box/chevy-parts was easier but not it/minty ) never ending tuning headache i think/remember they swapped it out in ( Kearney~ nebraska usa ownership/vin fyi on the one that got detuned/swaped, the other mans was don..../Utah and got sold around 1992~era ) 1982~ for a 360 or 340-6 and 518A-auto and had less hassles and costly ect and also comparing with their acquaintances with ford's/mustang's and 440/502~ 906-headed road-runner's/b-bodies biggest thing the bee broke was trans's/clutch's/torque-converter's( sprague or belooning-out/leak/broken-weld's and from that sometimes destroys the thrust/rear-main bearings in the engine ) and or driveshaft or rear-end bearing's/gear-set's and piñon snubber's ford SBF and side-oiler's was wash-down and or broken/melting piston's and or spun-rod's but my/one-of-them coworker liked driving fast in California/CIP-chased a couple of times at 85+mph the other's was hot and or dusty roads

They are great until the stop working because of bad electronics being most of our electrical parts are made in China now which are junk compared to when the Japanese were making good electronics back in the day . A buddy of mine he bought I think it was the Holley sniper fuel injection kit to use on his 70 Dodge Challenger with a built 440 and right away it started having issues where it didn't want to learn the idle & throttle perimeters and it would just up and die on him after multiple attempts & talking to the Holley techs that were telling him what to do to get it to start & run correctly & nothing made a difference so he took it off & it sits on his shelf in his shop with something that's not usable. I would be highly ticked off spending that kind of money on something that doesn't work correctly & if I remember he said that Holley wouldn't stand behind their product or give his money back on it so what ever you do bont use their fuel injection systems . My friend said screw it and just put a good Holley 4 barrel carburetor on it and he hasn't had any issues with it at all granted fuel mileage won't be as good & to start it a couple pumps to set the choke & prime it but at least he can drive it now he said . Even the modern cars trucks with fuel injection are having issues such as wires being chewed through by rodents computers & modules going bad stuck injectors etc all that can leave you stranded at worse or cause the engine to go into limp mode were it will only let the vehicle go about 15-20 mph if your lucky & if you have to climb a big hill on the road while in limp mode forget about that because there's not enough power to go up one so most of the time its calling a towing service to get it home or a shop to get it diagnosed and fixed .

Howdy Steve!

Right on, Blinkie.

Evenin'!

Right on!

Thanks, you too!⭐️

i also like 871+mechanical injections or cross-ram EFI on hemi's/440-platform but in the modern era EFI all the way on the streets

Nice.

Been told for years some Canadian Pontiacs actually had Chevrolet motors. Anyone know why???

​@pb68slab18 The cars were built in Canada. Chevrolet engines were also built in Canada. Pontiac engines would had to of been imported with import duties. All the while there was some Pontiac models imported into Canada with Pontiac engines.

​@@pb68slab18A buddy of mine has a Pontiac that looked like the Chevrolet elcamino but it had a Pontiac front end on it back in the 80s and it had a sbc in it. We had never seen anything like this before and I had a 70 Elcamino back then a 350 sbc and a 4spd transmission so we called a Chevrolet dealership in Fridley MN back then known as Viking Chevrolet and talked to someone about this Pontiac and he told us to call back in a couple of days after asking if we had the VIN numbers off of it which we did so we called back & he had told us that there were indeed some Pontiacs that were part Elcamino that came from Canada and this one had found its way to MN back then . My friend was a body man back then & acquired the car as a partial payment from someone he did some body work and a paint job for it & I had told him I think this Pontiac Elcamino was probably pretty rare because we never ever had seen one before just mostly the cars back the that were new or the old muscle cars at times that we would look at that were for sale cheap but in decent shape yet . Once we found out what this car was he ended up selling it right away instead of doing the body work on it & fixing it up so e then selling it so he must have needed the cash instead . He was more of a Mopar guy and had a 69 & 70 Dodge chargers both big block cars and the 70 had factory power windows and the nicer interior than the 69 had . He ended up fixing up the 70 and was drunk driving it 1 day & ended up rolling it and totalled it out & ended up parting it out & selling the interior to another friend of ours who had a 69 Dodge Super bee which he still has to this day .

Not a 65 vert., but a 64 2 dr. HT. Back yard find. On blocks for many years. 409/425 4 sp. bucket seat car. Orig. engine and rear. Trans. had been changed out. Verified by PHS Canada. Found in Thunder Bay Ont. Canada in 2023. Saw it in person, have the pics. Rare piece of muscle car history

There is no "twin efi"... this is direct port fuel injection on a single plane dual quad intake.

Thank you!

You're welcome!

Thanks Nick and crew it's a awesome way to start a week

Good point.

Same to you!
