351 Cleveland Inline Autolite Intake Manifold for Pantera

[@necro_nemesis]

It must be incredibly satisfying to see this meticulously hand crafted precision mechanical art sitting atop a bygone era engine in action. Next level hot rodding few have invested themselves in mastering.

Simply Awesome work Mr. Coffield. Definitely would love to see some more of the manifold video's, &&&&& some of them mounted on the car they live on with that wonderful sound they make as well. Thanks for sharing your wonderful hobby & exquisite work. Best Wishes & Blessings. Keith Noneya

Man you got RIGHT and in the centre ,doing what you love, helping people out developing and improving your skills Wow I really love your program, pleasure to watch 🙂

[@theshed8802]

Just artwork Kelly. As much as I enjoy your casting videos, these videos are every bit as good. Going through the project from start of the concept, through to the finished assembly, including the machining, adds great value for me as a viewer. Thanks very much. Regards Greg

This is the best channel on KZbin. The most interesting and informative. Thank you for sharing your knowledge. Endless respect!

[@rickhalverson2252]

Enjoy all your videos. You need to be featured in Hot rod magazine. Covering some of your projects. Absolutely unbelievable work. Nobody does work like this. Let's melt some aluminum. We can make this ha!

[@Hydrogenblonde]

That is a absolute masterwork. The highest workmanship!

[@davidnunn9583]

Kelly, Beautiful intake. Truly a work of art!

[@kellycoffield533]

Hey David, the owner is (sort of) in your neck of the woods, PNW. Best, Kelly

The stick out when cutting some of those ports is extreme. Lovely work.

[@kellycoffield533]

If you're talking about the router position while cutting the plenum plate, I agree. I would have built a machining platform to elevate the cutting surface and reduce that distance but the problem is the router can only be adjusted upward 1 to 1 1/2" before it hits the Z stepper s it hardly seemed worth it. Though the MegaV is a decent hobby machine, it leaves a lot to be desired for this type of work and I have a slew of upgrades n the works which include linear rails in all axis, additional Z travel/envelope, spindle, and in general much more rigidity. Maybe I'll do a video on that too? Best, Kelly

[@OhHeyTrevorFlowers]

@@kellycoffield533 hey, I was writing about the ports on the main body of the manifold. With being so close to the elevated features it seems like you’d need a long tool to reach the port locations.

[@kellycoffield533]

@@OhHeyTrevorFlowers Ahh, I see. Also true, but the combination of the radial drive tool holder I discussed in the video, and the MT2 to R8 adapter provided adequate reach. That is a lot of stick out but with the pilot hole already drilled there is hardly any material removal with the form tool, and cutting aluminum isnt much of a chore. Probably a little greater risk for runnout with those adapters but well within tolerances for such an o-ring sealing port and miles better than a pipe thread IMO. Best, Kelly

Too bad you didn't get any video of it in the car running. Clevelands just have a sound like no other. I miss mine every day.

[@pauljanssen7594]

Nice work, PCV valve very nice.

[@jamesford2942]

That is a sweet intake and carb system. Thanks for going into all the details of making the intake.

NEATO. CHEERS from AUSTRALIA.

[@SpaceAp3]

Inspiring work. Has encouraged me to design a casting furnace, should be cutting a keg open soon!

[@janwall2648]

I love your attention to details, please keepposting this kind of video!

[@shadetreemechanicracing22]

There is a lot of oil splash in the valley, so that baffle is a great idea.

[@GooseGosselin]

Amazing work, would love to see it on the car!

[@echadmiyodea]

Amazing machining skills.

[@ODGColornChrome]

Awesome work! Just because you enjoy it, only reason you need. Keep it up!

[@charleswahlert3353]

Great job Kelly. You are an inspiration!

[@jonathanwaugh1433]

❤ thank you ❤ Love your work😊

[@0160564]

Absolutely incredible.

[@TomChame]

Absolutely beautiful! Thank you

[@bryancondrey6457]

Beautiful Work!!

[@dabooge]

Does your customer have a youtube channel? I'd love to see this beauty mounted and working

[@chrisshorman522]

Wow. Amazing work. Great job.

[@johnnolte952]

How can we get in touch for special orders such as this.

[@noneofabove5586]

Expert level 10!

[@johnnolte952]

I’m impressed.

[@terrydondaneau4115]

OUTSTANDING!!

[@thomasrahm]

Wow, amazing work!

[@bigvanillasmooth6772]

What a beautiful piece! I wanted to ask how to get a hold of you for a custom adapter intake for a 335 series engine?

[@kellycoffield533]

There's a contact email on the front page of my website www.inlinecarb.com Dont send big files to that one, but reach out there and mention this post. Best, Kelly

[@ms24444]

You are a king

[@algiecompositeaircraft5629]

Amazing work you do, as always. Wondering if the vacuum plenum might fill with fuel over time, there is always liquid fuel running down port walls, with each pressure pulse a tiny bit could be sucked inside there. On another note, I am working on a 4 cylinder two stroke 1000 cc V4 engine, based off YZ250 cylinders and rotating assemblies. Have studied all your videos and will cast the multiple crankcase halves based off your teachings. If you are interested, look up Algie Composite Aircraft on KZbin for my channel. Thanks!

[@kellycoffield533]

It's a fair thought, but after decades of practice, I can confidently say it just doesn't happen. As to why, I suppose it's because in-flow is balanced by out-flow, and the plenum spends at least as much time well above rather then below the vapor pressure of gasoline, so even if some fuel temporarily comes out of suspension, it promptly evaporates when exposed to high vacuum. Same is true at brake boosters and other vacuum accessories supplied by manifold vacuum. I've done a lot of work with two-stroke engines over my life. I'll have to check out your channel and engine project. Ever watch Alan Millards motorcycle engine builds? Best, Kelly

[@Fredness2300]

Amazing.

[@lawrenceveinotte]

Great video, thanks

[@44coma]

😊great work.

[@allentighe9947]

Awesome

[@Hazzy238]

Does this system work with bronze casting?

[@kellycoffield533]

Yes

[@glenc90240]

How do we get in touch with you about a one-off manifold ?

[@kellycoffield533]

There is contact info on the home page of my website www.inlinecarb.com

[@jameswieler3295]

How much?
