Tuning Secondaries: Holley Style Vacuum Secondary Carbs (Extra HP)

A lot of folks never touch this stuff, but it really does make a big difference.

[ThunderHead]

Like I said guys, this is very much so tied to the "seat of the pants" feel - if you know what to look for, you can really make a big difference on a vacuum secondary carb.
Links to tuning bits are listed in the video description. thanks for watching guys - more importantly, I hope the video was helpful.

Everyone needs a little extra street torque. Love the music in the beginning.

Excellent description concerning vacuum. I learned and gained my information from shop manuals and I still have those manuals. I'm soon to be 74. Learned a lot in the 60s and 70s. Keep up the good work.

That was one of the cleanest 2nd gen rams I've ever seen.

Brother your videos have helped me so much over the years ! Thanks again for sharing .

[jewllake]

Good stuff! Uncle Tony did a similar video on this also. I love my 4100 Carb on my 64 Galaxie with the 352. It was your video that finally got me to tune mine correct and she can spin the two tires with my posi unit in the rear.

Truly glad to see you back absolutely enjoy watching your videos just goes to show you can teach this old man new tricks thanks

[rodneybrand]

Glad your back..your knowledge of carburetors is impressive..

[paulgusmus]

I'm glad you are back on videos. I may not catch everything you say in one viewing but I actually learn a lot from you. Carbs were always a mystery to me and I believe that if I need to work on one I can go back through your videos and find a solution to my problems. Keep on doing what you do.

Wow, I’m dreaming! I had a ‘72 Maverick, 4 dr, with a 302/5.0 and that, even stock was quick. I did a good manifold cleaning and had true dual exhaust put on, along with rebuilt transmission/shift kit. Pretty good runner. The one thing I never got around to was the diff, it had a 2.74 pumpkin, not enough to scare the big boys, but solid enough for me and good highway mileage.

[randyekman]

happy to have you back. I squeal a little when I see you've posted a new episode.

[nathanbrowne]

Hey man. Great job! Nobody else on YouTube speaks as much about carburetors on old fords as much as you.

[danielfisch]

Thanks for explaining the carbonator and sharing another informative video.

[johnbauer]

I love the info, you are amazing, you have me all excited about working on My 1968 Dodge Truck with 340, thanks for inspiration

[chadoakes]

Thank you for the great knowledge Luke and for all your help working great videos

[davidmckinney]

Hello uncle luke 👋 glad you are back buddy 👍 it makes my day with your notification

[dennisborg]

You rock. Love to see younger people like yourself who just are gearheads. Don’t worry about the paint job or what the interior looks like. Just so it hauls ass.! Just like we did it back in there 60s and 70s. All your money goes into engine and transmission and go fast. Who cares about how it looks. Also I got the same beer bottle opener ring.

[lyricaldreamer]

Luke, Thank you for that explanation! As an older guy who grew up with '70's GM 350's, Chrysler 318/360, etc..that 'bogggg' then ' 4 bbl howl (yeah, flipped breather lid lol) we thought that was normal.. Now in my 50's, I realize how much faster my old school big body Lemans, Cutlass, Caprice, Fury etc, could have been. I still love the early/mid 70's boats, (84 hs grad lol) but man, a 4bbl, shift kit and duals with glasspacks, hrs of cruisin fun with under 300hp!

When I get my Mustang done this spring, I'm making a road trip to see you for a tune ;-)

[aarongrabowski]

Oh boy. Now that he said “minty”, i hope it wasn’t your peg leg you got the gas on!!! 😂
