Down leg vacuum secondary for me... 🏁 Love the tech talk, Ben. As always, Thx for sharing. 🏁 Happy Holidays to you and your family🎄. Precision of the build out weights the parts.
Thanks Ben. Remember Darin Morgan talking about when they llayed back the combustion chamber more behind the intake valve on a pro stock engine and it made more flow. But on the dyno it lost 40 ft. Lbs. In torque.
Yes any aerospace technician like myself are aware when you depart at more than 15* combined angle, the airflow "might" follow but the heavier fuel particles will separate! Then we have a disaster when the spark is lit.
Great video Ben. I certainly appreciate all of the great Tech. Always been a fan of the Annular Boosters. And the Downleg Boosters. Thanks for sharing all of the great cylinder head and carburetor and manifold information. Merry Christmas to you and yours. Have a great weekend. 👍🇺🇸👍
Great insight Ben, always Love these informational videos. Great for listening while working in the shed. You guys are freezing, we have heatwave conditions on the East coast and inland. Merry Christmas. Tim Australia 🇦🇺
I'm one of your every video watchers. If you have the time , go to Salter Racing Engines and watch part 1 and part 2 time to get serious about horsepower. he has other videos that are worth watching.In others he talks about valve angles and their margines. How far down on the piston the rod should be located, so in short watch them all. WISHING YOU AND YOUR FAMILY A MERRY CHRISTMAS.
That's very true about the steering. I have both. 1 hydro and 1 electric. Very different feelings. On my Ls3/6L80E swap I am going to be running a Ford/Volvo electric hydro power steering pump. They have an electronic controller on EBay, so you can adjust the feel on the fly.
To me, Dynos are great for break in and to see where the power band is. And give you an idea of power output. Flow bench just say MORE MORE MORE!!!! LOL!!! They are good to let you know if your messing up the heads lol!!!! Great info brother!!!!
Thanks Ben. At 57 I am always learning. What it your opinion on putting a Burr or dimple finish on the main secondary body on a Quadrajet to help brake up the fuel?
I made a "pressure drop" flow bench about 4 years ago to mess around with some old iron Ford heads. On the first pair, after alot of grinding and testing, I did find the point where nothing improved flow...it would not flow better even with the valve removed. I have since learned that I could improve flow by working back the short turn at the expense of low lift flow...so I took only a little off. Of all my junky old heads, the low lift pressure drop on those heads is only beaten by some Cleveland 2v heads. I think the "yank" you talk about in overlap is something the flow bench will never understand, and only track testing would show, and I have to believe the .05 lift flow # is important to a good yank. I suppose a bigger intake valve gives a bigger curtain at every lift point, but if everything is maximized with a small valve first and the big valve is installed last? My ideas are probably sorta like where you were about 50 years ago 🤣🤪🧐 It is always a privilege to listen to Dr. Alameda!
@@benalamedaracing2765 they are C9oe 302 heads with what I think is a 58cc chamber. I cant remember if I cc'd them. They entertained me for many hours....dont know if I will ever use them or not.

Happy Holidays to you as well sir. Down leg gives about another 20-25cfm on the flow rating of a carb.
@@benalamedaracing2765 Yep, 30cfm on mine. And don't forget the REO.
Thank you very much Ben. I always learn something with your videos.
Glad i am able to help Frank! I also learn from many responses and like I always believe a good teacher was once a good student!
Merry Christmas Alameda Fam. Blessed to hear your professional standpoint on any subject!
Thanks and Merry Christmas!

Thanks for your suggestion and for your support of my channel.
tony and tess are giving away a set of those new trick flow heads at pri this morning.first set
they said those new heads flow 342 at .650 lift out of the box
If you see them tell both I said hello!
great video ben, thank you, merry christmas to you and your family
Thanks Mike and for your support of my channel!

On a road I like to feel the tires grip to the surface and electronic steering fails to do this big time!
Thank you Ben. Wishing you a Merry Christmas.
Same to you Gabriel!

Yes finding your powerband is very important to know.
That was a great video, Ben! Did you try modifying a down leg booster before switching to annular ? I haven't , that's why I ask.
Yes I have and still no comparison on its performance.
Thanks Ben. At 57 I am always learning. What it your opinion on putting a Burr or dimple finish on the main secondary body on a Quadrajet to help brake up the fuel?
I have to see what you are referring to. As long as the departure angle is not above 15* it might work and anything beyond is any ones guess,
I have a question you may know why .
Is it common to put studs on the main caps on an aluminum block ?
It was a TRACK-BOSS 351C ,
Aluminum block
If you are making serious power yes it is the best way to fasten the mains and keep it all together!

Thanks dude!
I grew up in the 60's & 70's
I only knew of TOP FUEL doing that.

Anything to improve flow on those stock castings will surely help! What kind of heads are you using?
