This 7 year old information is just about useless. The quality of cams and lifters has gone to zero. The failure rate is SO HIGH in 2023-2024 with any brand of flat tappet cam and lifters. Why gamble your rotating assy? And your block and oil pump. Save your money and get everything you need to go to a roller cam, lifters, pushrods, springs. Zero break-in. Next to zero failure rate.
Fuel Injection was on option on the 1957 Chevy Small Block V-8. It was all mechanical and you had to keep it tuned. GM Service manuals are very comprehensive. The Rochester Fuel Injection units bring big dollars today .. Seems I have seen modern systems that are built to look like the Original ones..
buy a Holley instead,can you imagine having to use an ADAPTER to put a Performer on a performer manifold of the SAME brand.Just a way to make you buy MORE STUFF
Does one have to use an Edelbrock Intake Manifold to take advantage of this system or can you use say a LS3 Intake Manifold and achieve the same results?
I know I'm 4 years late to the party, I wouldn't say anything about a youtuber or a home garage mechanic, (which is what I am at best) but this has the EDELBROCK USA stamp of approval on it. I am not an Edelbrock hater, I have-a-bunch of their stuff and I really like all of it, so here is my burnt oil under the fingernails observations. 1. Mr. August Cederstrand is a Reginal Account Manager. I assume he's not a Certified Mechanic, or they should have put that on the screen as well. Shame on you Edelbrock. Too bad corporations are more concerned about engineered image than practical information. Which brings me to 2. If your Engineering Department calls it Convex or Concave, please clarifiy. It is just a description and not a procedural catastrophy, but it has caused quite a ruckus, Shame on you Edelbrock. 3. I may have drained the old oil before I took the motor out of the vehicle, or even broke down the motor to remove the old cam. I like to pull the pan, make sure the oil pick-up tube is secured, and put a new gasket on, just a personal thing.
Your e-mail captured my interested but I want more power and higher RPM's I suppose I need to research your other models of heads. I am really surprised they are made in the USA Commifornia no less.
Why the hell don't they make a 400 or a 350 CFM 4bbl for smaller sht ? Holley owns that market solely because Edelbrock doesn't make sht for v or inline sixes that doesn't turn 10k rpms.
None of this high rpm break-in makes sense. The opposite, low rpm does make sense. No car factory ever breaks in an engine first start, not ever, for over 120 years. Start the engine, drive it to the parking lot, turn it off. How many engines have been stored for 1, 30, 70 years but start and run fine? Abandoned in a field? No lube at all, dry. The cam turns 300 rpm at 600 rpm idle. The lobes are actually pushing the lifters ~1/3 of that, duration of ~120°. So about 100 lifts per minute or 1.7 per second. You can blink or tap your finger thrice as fast, for perspective. This is trivial and breakin grease or even oil is plenty. When you raise the rpm 4 times idle you have increased the velocity at which the lobe approaches the lifter and the speed that the lobe wipes accross the lifter thus increasing friction dramatically. Like starting a fire by twisting a stick on a piece of wood slowly vs very fast. And pump oil pressure from lifter bore and crank slinging takes a few seconds. Someone should make a test rig of an engine with cam, only 2 lifters and 2 valves and springs. Put a motor turning 300 rpm on the cam with NO lubricant and measure the temperature rise vs time. If the surfaces are hardened properly there should be no wear. Then raise the rpm to 1200. A drill or a lathe tool with no lube experience much higher pressures and dont dull unless the rpm is very high. Best of all, get a sixties GMC V6, the cam is IN a pool of oil at all times. As far as rings seating, use a bit of thin oil and low rpm. Never had problems and engines I built 30 years ago still run fine.
That's great man I'm sure comp cams, Edelbrock, Howard's, crane, lunati, and all the other cam companies have no idea what they're talking about. They didn't build an engine thirty years ago and offer terrible advice on a RU-vid video comment section. Everyone should take your terrible advice. Especially on how splash lubrication works and friction works 👍
@@maxsinger3526 Read my comment again. Slowly. Focus, concentrate on each sentence. Then critique each one, explain where I'm wrong. After years of investigating, Powell machine and others have determined that flat tappet failure is not a hardness issue. Maybe a crown and cam slope issue, i.e. crappy machining. Powell no longer has anything to do with flat tappets. Failures began after the myth of high RPM breakin. The myth of crank slinging oil is absurd. A new cam is installed with break-in grease, that's why it's called "break-in grease", that's why Isky and others supply it with the cam. High RPM slings the grease off. The goal is to mate the contacting surfaces without excess friction. Prime the oil pump with a drill and look at the lifter bores, if they dont weep oil directly onto the cam lobe you have a problem. And a drill on the oil pump is equivalent of very low RPM.
My 1406 on my pontiac 350 accelerator pump is shot carb is 25years old should I rebuild or is it worth rebuilding or just slap a new 650 electric choke carb on it can anybody help me decide thank u
So on the 122 you say you need a carburetor. I have a 1993 c1500, with a custom built tbi with bigger injectors that flows at 650cfm, on an l31 vortec 350 with a mild roller cam and some work done to the heads. The engine and TBI is built for boost, with a double sealed needle bearing and 46mm bores. Tuning is with EBL Flash II OBD1 flash tuning system from dynamic EFI, with a 2 bar map sensor so I can tune for boost. The TBI is good for a little over 500hp, between fuel and air. Is there a reason why you guys say carburetor only? Weiand used to make a similar roots type blower I believe, that wasn’t intercooled for the TBI engines, so why wouldn’t this work?
There’s no reason to have terrible rock music at mind numbing loud throughout the video nobody wants hear that crap. WE want to know about the parts and the price
Like was already commented there a lot of jets.....as cool as the carb is I'm a little concerned if or how much the carb has to be tuned for mild build street use....aka the 650 on a 428 Ford.....simple adjustments no big deal but would or could these adjustments open sorta Pandora's box to all those jet adjustments.....
1700 IS very EXPENSIVE, probly DOUBLE the cost of equivalent Carb. BUT wait thats not all, For this efi to work you also need a $600 fuel sump kit! BUT WAIT thats not all either. Summit has this listed as a 2400usd efi system plus the fuel sump Converted to CAD currency im looking at $4000 bucks right out the gate and wouldnt be surprised if a bunch of add ons needed bump it up to $5000 cdn dollars. Well the truck im putting it on is only $6000 !!
Gotta come back and watch this every now and again! He never worked a day in his life because he absolutely loved what he did, and he was damn good at it.
