Love seeing the products I sell at Holley being tested!

Holley single plane did surprisingly well on this small 5.3 engine. It would be interesting to see how it performed on a 6.2 liter.

Test that with the junk yard dog cam.

I’m building a 6.0 now that is getting bored with dish forged pistons for nitrous. Also using the junk yard dog cam. Can’t wait to see the numbers.

This gives me hope for that split intake on my boosted 6.0L 236/242 .612/.632

I've been wondering this SAME thing !

I've had my intake on order since before Christmas. Maybe by next year I might finally have it. Lol

I’d like to see the dual plane with a spacer difference as a comparison, and also a comparison between the Holley manifold and a super vic, possibly on a 5.7/6L

I basically did the same test with a 6.0 on the road. I started with a lq4 with ls6 heads a BTR nsr cam long tubes and a Victor Jr. a quick fuel 750 carb in a gbody. The victor jr cracked and I switched to a Holley dual plane. The dual plane is better all the way around!!

I have a Vic Jr on a .030 over 6.0, it cracked recently also, I’ve been thinking about trying a dual plane on it…

Richard I love your videos, but almost nobody is putting a N/A 4.8 into anything to just drive around! I agree 100% that if you were to just drive it around N/A the dual plane would be the right choice! But most people watching your channel are usually trying to figure out how to put a street race vehicle together, like they see all over KZread! Almost all of those vehicles are leaving off a trans brake & 4500 & running them to 7000+++! They are always traction limited! So they don’t care 🤷🏼 at all about what it makes on the bottom! I’ve even seen those awesome gigantic MAST & CID intakes on 4.8s & 5.3s! Or the cheapie big fabricated intakes! Guess what! Those are the guys who normally win on the street! It’s very rarely the guy with the sleeved L/S w a 4in stroke & 427 cubes & a fast manifold! I don’t want to argue, I’ve known for along time the better the N/A engine runs, the better they will be on boost! But unless the car is just going to be putted around N/A! I don’t believe anyone really cares about dual plain intakes 🙄🙄🙄🙄! I honestly think it’s been beaten like a dead ☠️ horse 🐎 over the last 20+ years! If they don’t know by now 🙄🙄🙄🙄! They will never ever get it 😂😂😂😂! I’m sure there are tons of street races out in your state! Maybe try to go & see what these guys do, especially with the smaller L/Ses! Thanks again for doing all the testing we all wish we had the time to do 👍🏻👍🏻👍🏻👍🏻!

Translation-you run a race motor and care about race motors-I get that. Others care about low-speed power-in fact it is the question I get most often (way more often than how to build a high-rpm race motor)

Would be interesting to see how far you could go with those factory rods now that's there's good pistons

I like how you just start naming the cam specs for us because we’ve learned what to do with those numbers and with the intake setup we can ball park a hp number for most engines just by getting a build sheet lol 😂

I'm building a forged 408 with rec port heads. Thinking of this intake. Should make good power?

I'm building a 3.810, 10.5:1 5.3 for boost. I love the look of the holley split intake with a Wilson elbow, but I know I can make more HP with a tsp sr1, or a fasst intake. I'd love to see this mother ran under boost with the holley split intake and the fasst, or tsp sr1, or even with a holley high ram back to back!

please see the cath port intake test video-the fast would likely be better than this single plane all the way up to 6500 rpm or so

Right on

Which is the lowest profile carb intake for Ls3/L92

A test with longer cam duration could nett some interesting results. I'm guessing a guy running this type of equipment is not running a 'race gearbox box, so the motor needs to pull from 3000 ish to get out of the turns?

It does well I'm sure

What happened to the GT45 turbo challenge??

Can you run A/c with a carbed ls?

Seems like 4.8 doesn’t have enough displacement for single plane intake manifolds at all. Lesson here is don’t use a single plane unless you have high compression,heads and huge camshaft to use it. 5.7 would be the lowest cubic inches for a single plane intake in my opinion

Let's see some comparison on a motor that actually needs an intake like this. This needs to be tested o. A 400 ci plus motor..

How is the holley vs vic jr?

I've got a 408 w/ 10.8:1 compression 317 worked heads and the Holley split efi intake and it made 590hp/545tq. I have it in a 64' Ford F-100

How do you decide whether to use a tunnel ram or a single/ dual plane intake?

@richardholdener1727

Жыл бұрын

depends on hood clearance, daily driver or not, but for just power, the tunnel ram should make more peak power

What exactly makes the split manifold perform so much better then the vic jr manifold i thought the split design was just to make access for porting, also would there ever be any issue with boost leaks on the split design even with the gasket. Im conflicting on what to use on a boosted 402 peak power around 7000-7500 rpm.

@hoost3056

2 жыл бұрын

Intake manifolds shape the torque curve. Dual planes have longer runners, and longer runners boost low and midrange power because they resonate ( think of organs making notes ) at lower and middle rpms. This is why matching everything takes work. Cam timing, intake, heads and exhaust is all a system that has to be optimized to achieve your desired results.

runner length

So I'm thinking of a project car. 2,200 to 2,300 lbs. road sports car. I'm looking for 400 to 500 horse power at around 7,000 RPM. Keep the torque somewhat low. Say under 400. I would drive this on the street with occasional road race track days. What I have in mind is a 5.3 all aluminum LS. I found an LM7 with 862 heads that looks interesting. Questions: Can the stock 862 heads support the above power? Without porting and intake valve size increase? I am wanting to install some kind of down draft manifold (such as a Holley EFI LS Intake Manifold with an elbow) in order to fit the engine in the car without butchering the bodywork. Any suggestions for cam and what manifold would be very welcome.
