Thanks for the video. Never heard of this engine, very interesting. You have a typo, "the Moer" (Moser) in the summary text. I don't ever mention little typos but this one might prevent someone who was searching from finding this video, so I made myself an exception. Thanks.
There was a guy in the Sacramento, CA are who built a big block ford that had heads more or less like this. He was trying to run it as a top fuel motor as I recall. I heard it fire up at the track a time or two, but never heard it actually try to make a run. This was back in the late seventies. Wish I had taken a few pictures of it.
Can we stop for just a sec and appreciate that this was made in 1970... Milling billet parts today is like brushing your teeth, it's everywhere, but in 1970!?! This is WILD
No big deal. How do you think cams were made back then? The only real addition to milling is digital computer control (CNC) with easily changed programs. Had to know what you were doing back then, now it's mostly trial and error.
@@toomanyhobbies2011 lol You're silly . A LOT of work was involved back then . Where do you think your ideas came from ? And what you have nowadays ... Geniuses like Smokey Yunick and a slew of other geniuses . I'm from that time and there was no CNC to carbon copy anything, it took some serious innovation . Most things are piggy back to what those MEN began .
Me too . I never got to see one torn down . I remember there was talk about it having staggered cam timing on the intakes, hence the single port for the intakes . One valve would induce the flow early and the secondary would pick up from there, essentially the duration was partially controlled between the events . That engine was a big influence to what we have today .
Yea. Today it's everywhere.. but in 1970 .. WASNT A CNC IT WAS AN HMC..HUMAN NUMERIC CONTROL😂.. IT WAS MILLED N DRILLED BY HAND MORE OR LESS.. NO COMPUTER DID THAT.. IT WAS MAN MADE
I'd love to see the OHC 4 valve chevy 350 that Honda built for Chevy in 1973 when Chevy was complaining that they could NEVER meet 1975 emission and fuel economy standards. Honda gave them a full size Impala that got 50% better fuel economy AND power with excellent driveability.
Sir Jack Brabam the Australian Forumla 1 Champion won the F1 Championship in the Brabam car built by him and Australian Engineering Company REPCO ( still around today) , they used a Oldsmobile Alloy 215 ci ( Buick Small Block) and heads quite simular to these in the early 1960s , they used the Oldsmobile version of the Buick as the olds had 5 head bolts per cylinder and cross bolted mains . The rest of the motor was a billet steel crank machined by Repco in Australia, billet rods, forged pistons , it was also 4 valve OHC engine , as stated they won the F1 championship against Ferrari, Lotus , Ford and all the rest with a originally a pushrod alloy GM motor . Probably the only GM V8 production pushrod car motor ever to do so..
@GregQuirin Story's not quite accurate. The Buick production engine made it's way to Rover, and Leyland, and people thought that was the same as the Olds version, and story had it be the basis of the Repco-Brabham engine, but it's not. The basis of the Formula1 motor is Olds V8 Indy Race Engine program, not the Production engine. The race and production programs ran in parallel, and are very similar.
@@PiDsPagePrototypes you are so far from correct you are stupid , it had nothing to do with Indy , nothing to do with any of that , the complete story is Australia's history , not some crap you heard , you want the correct story , Brabam Australia used the Oldsmobile version of the 215 ci Buick V8 , not some Indy crap , there are books written on this , Repco Australia built the heads , not Indy , it's a stock Oldsmobile version of the 215 ci , Australia did the heads , they even bolt to the original block, Rover was later , nothing to do with a mid 1960s FI motor , Sir Jack Brabam and the whole process is taught in schools in Australia, rite down to Repco building the motors and heads , so get a grip on reality, learn a few things , look up the official pictures of an Oldsmobile 215 being run , and go back to your mum's Kia

thanks for the video, i love this stuff. Id love to see a modern chevy 4.8L truck motor with Honda K24 heads. no idea if it would work, but these guys could figure it out.
It always made me wonder why the OHC V8's we say from the 60s/70s used one giant belt or chain. Double the stress, double the stretch. The Fords actually run a few extra degrees on the pass cam due to the massive stretch from the 7ft long jumprope chain.
I'd like to build something like this some day . Maybe a BBC version with a 3.76" stroke with a 4.5" bore, maybe larger if possible. It should take care of issues with the BBC heads. 478cid DOHC BBC, 32valve should be plenty for the streets. Especially if the cams can be setup for vvt! And a VTEC system would be awesome, I have played with the idea of modified Honda j series V6 heads cast for V8, to fit either LS or SBC, with VTEC and variable cam timing. Have basically two cams on each shaft. One with .500" lift , and about 220° dur. @.050" and the other with about .596" and 260° @.050" with both cams having independent variable timing. Maybe use a BBC oil pump and modify the lifter bore oil supply to operate as piston oil squirters! Use a plug,threaded to allow a squirter to be bolted in. With a long bolt and safety wired on the top side. Maybe a high volume pump can supply the oil requirements. Enough for the vvt, VTEC, and squirters. I'd want to cast and mill a completely new front for the engine block To bolt on, with a new timing cover, and a bottom end girdle, to then require a custom oil pan. The girdle bolting to the pan rail, and the main caps. With the front engine cover bolting to the heads, and a timing cover bolting to it, and valve covers bolts to the head and front cover. The front cover possibly allow use of a different style water pump Maybe a LT water pump can be used or LS, maybe a old 250 I6 water pump, using custom pulleys. Possibly use a micro controller programmed to read the manifold pressure ( map sensor) throttle position, and engine RPM. To determine when the VTEC kicks in, and where the cams event timing is advanced or retarded. Basically when under load at low rpm, set things up to produce tq. It may also need to know what gear the transmission is in. EITHER way if the rpm is climbing decently fast, at full throttle. The VTEC can change the cam to a 3500-8500 rpm cam profile above 4200-4500 rpm, or a manual control activated when idling around. To get a radical rough idle. And extremely low tq! At idle but with 10.5:1 it should sound great . Maybe the Honda followers can be used ina head cast for a Chevy engine, using possibly larger valves. While still using the stock style intake manifold. At most using adapters. Possibly the exhaust flange pattern being the same as well. At most using an adapter to use a common flange pattern. Maybe a SBC going to a LS pattern . It could possibly use k series exhaust with adapter to LS or at most a custom flange with ports that can align with either LS , BBC, or SBC, so existing headers can be modified to fit. Maybe a SBC engine using an adapter to allow a narrower BBC intake manifold. (With larger ports) it will be longer, however with the custom front cover, the engine will be longer also. Maybe the BBC intake is the way to go. And epoxy the floor of the manifold to get the ports slightly smaller. A 383 with BBC intake and a 750 Holley carb. 32valves , it should make about all someone could expect from a engine from idle to 4000 rpm, then the cam change, (VTEC) and have the top end from 4000-8500 natural inspired power should be 2.25-2.5 HP/CID and the boosted power at one bar should double the output. At least 80% more, if the valves aren't too small. It should breath like an athlete in a hyperbaric chamber! With the ports raised in comparison to 23° heads. The intake runners at nearly a 45° angle to the valve stem. Intake and exhaust. Maybe get 383 with a 4.125" bore and 3.580" stroke, offset grind a crank to use a small journal rod or the Honda rods. Something already done. Or weld and grind a steel crank. Get a as cast crank in machined and mill in the stroke . Using 6" or , 6.200" rods. Maybe 400 pistons with the block decked , or custom pistons. Un-common strokes cost $$$. Maybe name it uncommon in a language other than English, 😆, put that much time and $$$, into something you gotta at least name it , possibly getting two 1.84" intakes and two 1.5" exhaust valves. It should flow near 400 cfm at 1" lift, maybe incorporate a slide valve in the head to get better low end tq. To close one valve and induce swirling in the cylinders! Maybe even have the intake valves opening at slightly different times having one open when the other is at .020" - .030" lift. To get the swirl started. And keep the quench pads large as possible . With the compressed air fuel in a small as possible and close to a sphere as possible. The pistons if domes, have a small hemisphere in the center carved out under the sparkplug. Keeping compression 10:1 or greater. 9.5:1 with boost. Unless it's over 3 bar. Possibly 11:1 on 93 octane, with water ethanol injection.
A Spokane racing group brought down a SBC to test in California for an Indy Car project that Tom Sneva raced in a different season. The Chevy produced more horsepower than the aufen hauser motor that was on a mid night express to race in 48 hours at Indy. The days of only one Dyno in existence on the west coast

@@charlesangell_bulmtl who knows it was probably this thing it looks like a porcupine when the cam boxes are off. It’s kind of confusing. It looks like they are cylinder head studs, but they’re actually the cam box studs
I give Chevy a pass. Yes they've built overhead cam V8s here and there and some were damn good. They realized that the benefits definitely doesn't outweigh the drawbacks. Something to be said about easily removing a head and popping it back on WO needing a bunch of new chains and guides,
Clearly trying to copy the Italians and Germans who had already been doing this for decades. Ferrari had made a 3L 4v V12 around the same time for the 312P making well over 400hp at 11-12,000rpm.
I'm not sure if the Italians and Germans were doing this before 1929 but Fred and Augie Duesenberg were making twin cam 4V engines (supercharged as well) during that year.
All you guys that thinks this was state of the art at the time obviously aren't too familiar with foreign engineering, my 75 fiat which is a dohc was originally created in the late 60 and Alfa Romeo was already using vvt in the 70s American engines have always been a little bit behind on engineering, these early manufacturers of dohc engines already had them fully worked out and very reliable, this is cool to see though, it's probably the cost and complexity that kept Chevy from manufacturing it in their passenger vehicles, makes me curious how a modern day version of this would be against the 5.0 coyote, in my opinion the coyote is one of the best small v8s out there.

@@alfredstewart5107 Obviously it IS a GM project as they produced it and if u would do one ounce of research u would find that GM was trying to create a stock block engine to compete with the Cosworth for Indy car competition. Good Lord man, at least do two minutes of research before u make a statement.
@@matthewmoilanen787 i did research and you are wrong. You are welcome to provide evidence proving otherwise.
@@alfredstewart5107 No you are welcome to provide me evidence of your claims. It's not my job to hand deliver you a note from your teacher. If you claim somebody is wrong feel free to prove it with evidence. I'll wait.
@@matthewmoilanen787 thats a lot of words to say you are wrong
