I Made an Engine Part !

Before anybody gets mad... this isn't intended as a promo...
Nobody here is silly enough to have a 348 / 409 anyhow ! Nope, I just wanted to share the results of what took 5 years, utterly countless hours, and all the money that will ever be in my life... To me, Stock and especially Super Stock engine guys, will appreciate and "get" this, better than most. It's an intake manifold. No, not a one-off, custom sheet metal piece. It's a fully finished casting, made from a multitude of drawings I did, which were translated into a pattern / mould, then cast at a foundry, then I machine them in my shop. Yes, of course, they're for 348 and 409 only. Single 4 barrel, single plane ( has never been one ), isolated plenum design. A little unique in a few regards. The plenum chamber, in hind sight, is a bit like a more consevative version of a "Merlin" for BBC. Anyhow, Here's a couple pictures of it installed on the engine in my station wagon. The engine itself, is a second time re-ring of an all standard size1963 425HP short block. Heads are aggressively ported "333" truck parts with 2.06" / 1.735" valves". Actual comp ratio is 10.4:1. Cam is my own specs, solid flat tappet, made by Comp... .565" / .578" net lift at the valve, 242 / 246 dur @ .050", 272 / 276 seat duration, 108 C/L. Used a set of Belanger design headers, made by Wilso Header Manufacturing... 1 7/8" tube, 36" length. This is the "6000" ( small port version ). |
Re: I Made an Engine Part !
Congratulations, Aubrey! It's a great feeling to accomplish something like that!

Re: I Made an Engine Part !
That's outstanding. I may have seen a 409 once in my life, and that intake looks so at home on top of that engine. Great job!!

Re: I Made an Engine Part !
looks great!!

Thank YOU, guys... I thought stuff like this would be of interest here.
I first installed it on the car, and road tested it. Was cool outside, and I had no thermostat, so the engine was cooler than it liked. It DID exhibit some low-mid range part throttle "stumble". I didn't like that. I can tell you this... after about 3300 RPM, it seemed that the stumble may have been looked after https://www.youtube.com/watch?featur...&v=U4ok_ykglOE Anyhow, I have since installed a proper 160 degree thermostat. ALL good now. It was simply important to have this "no heat" open plenum manifold with a little temperature in it ! However, in the inbetween time, we went to the dyno in Lacombe, Alberta, to ARL Automotive. Dyno was done by Dave, Allyn Lee's partner. We tested a stock 409 intake, an Edelbrock Performer RPM, and my "Speed-Port 6000", all using the same 750 CFM Quick Fuel Carburetor. Didn't come out exactly how either of us expected. Unusual results really. I have charts and graphs from the session, that document everything... A/F ratio , BSFC , air flow , along with a final comparison graph. |
Re: I Made an Engine Part !
True Hot Rodding is alive and well! Good job!

Re: I Made an Engine Part !
Now THAT, is Cool ! Good job !

Re: I Made an Engine Part !
II'd like to post a few charts... I KNOW you guys like numbers !
I need to find them, and get them re-sized |
Re: I Made an Engine Part !
Well done Aubrey !
Looks great. |
Re: I Made an Engine Part !
all i will say is that is a very cool story and good job!:) i an 40 and i have only saw 2 motors like this that the same guy owned:) very cool to say the least!

Re: I Made an Engine Part !
Guys, and Gals... I'm having trouble even locating these scans ! ? !
I made a compilation video that summarizes the development and dyno tests. If you don't have to have 50's/early 60's pop music in the background when watching a car video... you may like this ! https://www.youtube.com/watch?featur...&v=yej7CwbvOUE The charts are in there, and are legible if you run the video in full screen. You can stop the video at any point, to see the numbers. |
Re: I Made an Engine Part !
Wow!! Job well done. That is awsome to see...a true hot rodder!!
|
Re: I Made an Engine Part !
Very nice...so you didnt say Aubrey, what was your overall feeling for the end result?
|
Re: I Made an Engine Part !
Wow. Very impressive. What a huge undertaking. Congrats.
|
Re: I Made an Engine Part !
I heard you were interested in possibly selling these manifolds.What would be the approximate price for them, and are they available in large port( 690 head or Edelbrock head) versions as well as the small port version?
|
Re: I Made an Engine Part !
Amazing job, that's a real hot rodder!

Re: I Made an Engine Part !
thanks again, guys.
Dion... nobody has ever asked that ? ! Leading up to it, was so stressful, that I was actually having chest pains ! When the Edelbrock Performer put 35 HP on the stock intake ? The stress really set it ! HOW the heck could a manifold change do more than that ? First pull with my intake, had a "glitch" / stumble. More stress. Second pull... 465 torque, 462 HP Disbelief ! Because I was still in a postion to finalize the carburetor height of the casting, we tried a couple different spacers. 1" open, then a 2" phenolic 4 hole. 1" did nothing. 2" made a few more HP, but gave up mid range torque. Relieved Seemed that just as cast, was best scenario ( I'm not that good.... just got lucky ! ) So, cooled the engine down a bit, and did a last pull a couple hundred RPM higher. 466.6 ft lb torque @ 4200 465.8 HP @ 5800 Still a little disbelief. Quite frankly, the A/F ratio numbers are so steady, I'm uncomfortable even posting them. Doesn't look real. To me, I think the angle of approach to these goofy, almost horizontal intake ports in the heads, can be looked after, ONLY with a single plane manifold that accomodates them. That, I believe, is why it worked. Hopefully, this helps level the playing field for guys with these engines, using small port heads. A modest, hot-street build, should be able to make 500 HP. Comparable to a similar built oval port BBC. That has never been able to happen before. |
Re: I Made an Engine Part !
Impressive! Congrats!

Re: I Made an Engine Part !
Aubrey, that is really cool.
Having raced orphen engines myself ,I have a special appreciation for someone who goes to these lengths to race their combo. Congratulations! |

Re: I Made an Engine Part !
Take what Goldman says with a grain of salt, he's a little weird. Couldn't resist!
|
Re: I Made an Engine Part !
That's cool as heck! But how did it compare to the Edelbrock intake?

Jeff... You didn't watch the video ? !
Here are the basic numbers: Stock intake ( dotted line ..... ) torque 438.5 @ 3500 RPM horsepower 389.9 @ 5400 RPM ( 387.7 @ 5300, 387.6 @ 5500, 385.6 @ 5600, 383.4 @ 5700 ) Performer RPM intake ( broken line _ _ _ _ _ ) torque 448.7 @ 4200 RPM horsepower 424.8 @ 5700 RPM ( 422.9 @ 5500, 424.3 @ 5600, 424.5 @ 5800, 423.9 @ 5900, 423.0 @ 6000, 421.8 @ 6100 ) Speed-Port 6000 intake ( solid line _______ ) torque 466.6 @ 4200 RPM horsepower 465.8 @ 5800 RPM ( 464.8 @ 5600, 465.4 @ 5700, 465.7 5900, 465.7 @ 6000, 464.9 @ 6100, 464.4 @ 6200, 464.0 @ 6300 ) My sinlge plane intake held an AVERAGE HP of 412.... 37 AVERAGE HP more than Edelbrock. Torque was an AVERAGE of about 18 ft lb more. The amazing thing was 76 horsepower more than a stock intake. Holy $&#%, is the stock intake a piece of crap ! http://www.speed-port.ca/images/2964...81079af6b7.jpg |

Re: I Made an Engine Part !
No, didn't watch the video. That aside, that's pretty dang impressive! About now I'll bet Edelbrock is saying they should make one so sell as many as you can and recoup your investment. And I'm really curious about that, how much $ do you have invested (aside from probably countless hours)?
I was looking at adapting a SBC or Mopar B Victor type intake to my AMC when I was pursuing Super Stock. I don't see that happening. I spoke to Edelbrock and I was left with the impression they would build one but that's been two years now so I guess they don't have a real interest in the project. Now that you have a killer intake, turn that 409 into a SS! |
Re: I Made an Engine Part !
Thank YOU, Jeff... at least now, you might have a better understanding as to why I don't have enough money to make my Stocker better !
Super Stock ? Oh yes, it occurred to me. Just can't though. Rust free, original pint, inner and outer wheel wells... no WAY would I cut them ! Even if I got it to work on the 9" tire, I still would have to change rear end. naaah. gotta get that out of my head I need to sell about 120 of them, and donate my 300 hours of machining... in order to get to the "break even" point. If I can get a couple dozen in the hands of prominent builders, racers and rodders... I think I'll be OK ( as long as the large port works as well ). So far, I do have THE two major W block builders buying one right now, and wanting to sell them. It'll never be a money making venture. |
Re: I Made an Engine Part !
Aubry, I watched the video and I am impressed. You had to run a 409! You couldn't have run a 327, 350 or 400 small block Cheverolet. The reason I mention those engines, is because you would have a large market of Chevy guys to sell the intake manifold to.
I always loved the 1962 Chevrolet 409, 425 HP engines. Back in 1962, they were really hot! When I first started racing in 1968, you almost always had to make everything yourself. Traction bars, rims were narrowed to 4" to accomodate the 7" slicks we use to have to run. And the list goes on and on... From what you accomplished, I would bet you could build other in demand intake manifolds. The larger speed shops could sell the hell out of them. You need to try to contact Jegs, and Summit to see if they would be interested in your product. I am sure there is a market for your intake manifolds! Don't forget the big block Chevrolet engines! |
Re: I Made an Engine Part !
Congrats on a job well done. video is cool. that is some wagon. And a great soundtrack.
That is hot rodding at it's purist. Vic Sr must be looking down saying dayum, lol. |
Re: I Made an Engine Part !
Thank, John... Yes, I did inquire at Summit.
WOW... I send them a non-returnable sample. If they don't market it, they still keep the sample. uuuuuuuuuhhhh.... not in this lifetime ! Market is too small. I hope to sell 2-4 units a month.. if I'm lucky. To the guys who said to the effect, "this is hot rodding"... I take that personally, as the highest compliment... it DOES take the sting out of the poverty ! Chris... dayum... I can't even think of what to say to that ! thanks, man see... I KNEW you guys would "get it" ! |
Re: I Made an Engine Part !
If that's the stock iron 63-65 340 horse 409 intake,no wonder. just look at the #6 intake port at the flange. The whole W motor engine family had the most horrible intakes ever cast up. If they knew then what we know now!! That's the main reason that engine didn't breathe as well as it should have. Your dyno results showed a nice flat long power curve, making that engine way more useful. Amazing what a little technology does!!

Re: I Made an Engine Part !
“That Canadian guy….Bruneau…damm, we sure are lucky he wasn’t racing 35 years ago. He would have been major trouble.”
Comment that would probably be made today….from Bob Glidden to Jim Headrick. (I know Headrick is gone, but I digress.) |
Re: I Made an Engine Part !
Oh, and Jack Mullins called: He wants his wagon back.

Re: I Made an Engine Part !
Very impressive. I always look forward to news and videos of your 09.

Re: I Made an Engine Part !
Hey Aubrey
I am doing a 1963 409 For fellar. This thang was so rusty that I let it sit in weak Hydro-Chloric acid for 8 hrs so I could see what it wus. Have installed one sleeve, 4 businhgs in lifters. and 3 different main caps. Then had to bore to .085 over to get a ring to fit. Ross made the pistons. This motor is complete and numbers matching down thru the carburetors. Then he wants me to build him a 482 CI with Edelbrock heads. Now got another customer bring another from Alabama. Man am having a ball as I had a 63 around 1970. And the sound of 2 AFB's coming in still makes cold chills run up ur back. reed |

Gotta love that.... I looked into a patent. Yes, it was patentable... product with a widely used design, in an application never done.
However, patent lawyers explained to me, that all the patent does, is give me the leverage when I sue somebody for copying it. great Hopefully those production "leaches" realize that the market is so small, that there need only be one of us stupid enough to try and recover their investment,, yet alone make money from it. Thanks, Bunk... though I have a bad feeling that 35 years ago, I would havev been hot rodding flat head V8's... oh, wait a second.... 35 years ago, I WAS hot rodding flat head V8's ! ! |
Re: I Made an Engine Part !
Aubrey;
What a great story.. This is what "HOT RODDING" is all about, in my eyes... Have you thought about contacting these guys? http://www.lamarwaldenautomotive.com/ I like their work too.... Congrats on the success of your intake... |
