Camshaft 4/7 Firing Order Swap Explained

That would be a cool engine masters video comparing different firing orders

[@Ltmonte]

THIS is something I’ll be heavily looking forward to seeing on engine masters, since my 350 has most likely wiped a lobe. I’d love to see it done on a small block or something mild.

[@donrutter6765]

I wiped a lobe last year. Now my oil pump only puts out 20 psi at idle, 50 psi @ 4000 rpm.

[@dasboot9471]

You’ll make a hair more power going with a 4/7 swap…worth the cost of the custom cam? Not much more than any other custom cam

[@burntorangeak]

I feel better about my organizational skills after seeing this.

[@chucksgarage7165]

Built a 302 years ago and wired it up with the 302 HO firing order. Never figured out why it wouldn’t run. Towed the truck to a mechanic and he got it going for me. One of those things you learn the hard way.

[@hendo337]

Dave, that is a hell of a deep hoard in that shed. I would love to see a show where you just build something with a 35yrs worth of junk in a building.

[@jeanborsoi662]

I did it in my type 1 aircooled engine. Swapping from 1,4,3,2 (stock timing), to 1,2,3,4. It works very good, and I notice gains at middle and high rpms. Great content bro!

[@RustyorBroken]

There's another piece to the puzzle here. Engines are capable of changing the firing order on their own without requiring a cam change. I've seen it first hand. My '99 F150 w/ 4.2L went from 1-4-2-5-3-6 to 1-4-2-_-3-6 immediately after throwing a rod. I was towing a trailer of about 6k lbs and made it another 10 miles before the firing order changed one final time.

[@scowell]

Don't forget... you also have to swap the plug wires... it's not just a camshaft change! Loving the cheap camera content, subscribed!

[@dielauwen]

The reason they used 18436572 is to force exhaust through the crossover passage to warm the intake manifold and carb to prevent Carb icing , It does taste like gas so do not lick it. It also causes that off note in the exhaust sound as well as reducing the expulsion of gasses. With fuel injection you don't need to do this .

[@zz7qvl]

My 4/7 swap 540” has had the same main bearings for about 4 years 400+ passes, 2 sets of valves springs. Spinning to 7600. And they still look great. So I’d say, in a high rpm application it’s easier on the main bearings. A stock firing order stroker BBC spun high is tough on the mains.

[@russrogers3106]

I learned something I never knew about FORD firing orders! Thanks Freiburger!!!!

[@anthonysgarage]

The 351W has had the late firing order since its inception in 1969. So Ford had the LS firing order since '69. That's why Windsor motors and H.O. 5 liters always sounded so good.

[@stevie..d..pontiactransamm1215]

Warren Johnson was doing the 4,7,2,3 swap firing order back in the late 60's with a SBC 350 with 6 inch old's connecting rods. He brought it to the KALITA TEAM BACK IN 95 WITH THEIR MOPAR PROGRAM.

[@bigmike8847]

I remember hearing something about this wayyyyy back in the day on Powerblock TV. Good to see I didnt imagine it

[@farmerjim-fat-man-do]

If you renumber the cylinders on a SBC the firing order is the same as an early ford 302. The HO 5.0 firing order used on later engines uses the 4-7 swap. The 5.0 firing order sounds different (as does the the 4-7 swap on a SBC) when running but i dont think power is any different. Would like to see results of using a cam with same specs on both firing orders. Long term reliability of engine may be effected by the swap.

[@farmerjim-fat-man-do]

Guess I should have watched the video before commenting🤣

[@MaxAC]

Thank you!!! Ive heard of the 4-7 swap since I was in high school but never seen it done. I heard of a few people just swapping spark plug wires but that was stupid to me and they said it didn't work too well. Thanks for explaining it better.

[@ViewThis.]

I used to think that all you had to do for the 4/7 swap was swap the spark plug wires. So I did. It was a 406 sbc. I didn't know at the time it also required a special cam. My way of swapping made no difference that I noticed. That 406 rand so good even on 7 cylinders, so my screwed up swap just wasn't noticeable.

[@jacquescrusan9500]

For those of you wondering about the significance of the 4/7 swap and why this is important/worth doing (bear with me, this isn't an easy or short explanation): Note: I'm basing the history portion off of what I've been told by local engine builders and my dad/grandpa; the rest is based on college-level understanding of metallurgy, fluid dynamics and heat transfer... Way back in the golden era of hot-rodding (early 1960-s to early 1970's) drag racers were starting to climb towards the maximum of what their vehicle's engines could achieve, which led to finding the limits of stock hardware. However, there were a few problems that were commonplace amongst the hot rodding community that no one seemed to be able to escape. This phenomenon was what's called (and I'm ad-libbing here because I don't know the correct terminology off the top of my head) butting the ring ends. Butting ring ends together happens when cylinder temperatures get too hot, allowing excess heat to be retained in the compression ring material. As material increases in temperature, it tends to grow in size (volume), and this expansion process follows the path of least resistance, which ends up with rings growing to a larger diameter than normal, which shrinks the ring end gap. This continues until there's no room left for expansion, and then suddenly, the ring ends butt together, then simultaneously catch on and seize to the cylinder wall. Since there's not a lot of piston material above the compression rings, the piston material fails under tensile stress, fracturing into multiple pieces and causing catastrophic cylinder damage. So the question is: how does this happen? The main culprit is the design of the engine block itself. Back when the Small Block Chevy (sbc) was introduced in 1955, it was designed to be a relatively simple engine. However, this came with a myriad of problems once the design was pushed well beyond it's intended purpose. The most damning of these shortcomings was the design flowpath of the engine's coolant through then engine block, combined with the other culprit: the stock firing order. As Freidburger stated earlier, the firing order for most classic american V8's was 1-8-4-3-6-5-7-2 (when looking at it through the layout of a chevy engine). The coolant flowpath through a sbc goes from the water pump, into the front of the block, through the water jackets to the back of the block, then up through the cylinder head, into the bottom of and through the intake manifold, then through the thermostat and its associated housing at the front of the intake manifold, out via hose into the radiator to cool off, then sucked back into the engine via water pump once again to start the flowpath once more. This is where the issue resides. For context, there's always one pair of cylinders in a crossplane V8 that are part of one cylinder bank that fire right after one another, that are located right next to each other. For the original sbc, this is cylinders #5 and 7. For the late model Ford Coyote 5.0 V8's those cylinders are #4 and 2 (still using sbc numbering) and for LS/LT engines, the cylinders in question are #3 and 1. These two cylinders firing right next to each other AND right after one another generates a 'hot spot' in the engine; a concentrated are of higher temperatures compared to the overall engine. So the issue with sbc's and their original firing order is that it places the 2 consecutive cylinders at the back of the engine, which is furthest away from the coldest coolant entering the engine (remember that coolant flows from the front to the back of the block). This presents an issue where the two hottest cylinders are receiving the lowest amount of cooling. Hot cylinders transfer heat to compression rings, which causes ring ends to butt together, which causes the failure that i mentioned above in paragraph 3. So how do you fix this? Simple. You move the hot spot as close as possible to the front of the engine, where the coldest coolant is. Granted, this doesn't 'get rid of' the hot spot, it moves it to a place where it can't cause damage to the engine. So now you've done the 4/7 swap. What does that mean? It means that now our firing order is 1-8-7-3-6-5-4-2. This means that our two hot cylinders are at the front of the engine, on the passenger side, identical to a Ford Coyote (funnily enough, doing a 4/7 swap on a sbc dues give you an IDENTICAL firing order to a Coyote...), and now the problem has been mitigated. I hope this helps. *Side note: Due to the more even firing order between banks, this configuration tends to have better fuel-dispersion properties, meaning that your air-fuel ratio disparity between cylinders is decreased by a noticeable margin.

[@unclecowboy2003]

Hi your explanation is fairly correct but we always were taught to file ring end gap for expansion and the 4 7 swap cam was used in corvettes as early as the late 50s as I was taught that from a gm engineer that worked on them anyways thanks for your explanation it was great

Love the sound of the early yblocks, they have a distinct hot rod sound.

[@skatedoof]

Slightly different question: Why was the firing order engineered as it is if the swaps have benefits? Do they have any negative side effects?

[@bgd73]

the shared rod pin is theory, not actual physical rotation balance.. hence options. You can have a self balanced v8 with benz crank throws.. but engineers are afraid of it (note the benz crank is not a flat plane... totally different).

[@snek9353]

The only real benefit is to intake and exhaust manifold design. With 18436572 5 and 7 are right next to each other and fire one after another. So if those two cylinders share manifold passages the flow of one disturbs the other.

[@DieselRamcharger]

[@b.s.adventures9421]

I thought that was the deal with fords firing order but never was sure. I also assume that’s why the 80s 90s 5.0 H.O. Have a slightly different sound to em. They sound awesome.

[@DaveMcLain]

On a 90 degree V8 with a 90 degree crankshaft you will not hear any difference in sound due to firing order. Why? Because no mater what you do with the firing order you still always have two cylinders that fire 90 degrees apart on each bank.

[@markvaughn461]

[@TRX450RVlogger]

I discovered this with my 1990 Bronco it has a 5.0-302 but has the 351-5.8 firing order. My neighbor is a Ford Mechanic it turns out someone in the past has installed a 351 Windsor cam in my Bronco.

Here's what the 4-7 swap looks/sounds like kzbin.info/www/bejne/d5Xck5iad5yeZ6M. Interestingly a crossplane V8 has 8 possible firing orders - 4 of these fire all cylinders in one bank followed by all cylinders in the other, no production engine has used that. It gets confusing because of differing numbering conventions (as you mentioned) but from what I've seen only 3 of the remaining sensible 4 firing orders have ever been used. Not sure why.

But you left out why, to swap cylinders... I am sure there is an awesome hot rodder reason and l look forward to learning it from you!

[@danieldimitri6133]

The actual issue is nobody really knows. The explanation with the intake manifold is bunk. Sure you break up the 5-7 pair but you create a 4-2 pair or a 3-1 pair. The only thing that we are certain of is that the ls and ford ho pattern has more even bearing loading since an entity as large as Ford took the time to study it. The 4-7 swap should be similar as both orders fire from cylinder 8 forward with 1 cylinder as an exception being #3 for the 4-7 swap and #2 for the ls/ho firing order. While the traditional order jumps around more.

[@garybrinker4522]

To help lessen heat buildup in back of the block,,sense coolant flows from front to back of block..(Told by another comment above)..

Funny thing, this still doesn't cure the traffic jam that happens on a V8. I'm talking about the left-left then the right-right in the firing order. That makes balance/H/X pipes more necessary.I like the 6cyl concept, L,R,L,R,L,R or F,B,F... the firing order is balanced. Split a six and you have two 3 cylinders 180 out of phase from the two pipes. That's what gives them the bad rap. I wonder what a perct L-R exhaust note would sound like from a V8?

The two things that every internet/old-school car guy knows are that: 1) Back pressure makes horsepower. 2) Different firing orders (on a cross-plane V8) sounds different. Hey, maybe they all still feature two opposing-bank pulses followed by two same-bank pulses... but whatever. It's that TONE. Bonus: 3) The two-man bleed is obviously the best, most efficient brake bleeding technique. Open the bleeder with a clear hose (if you want to see what's happening) attached running vertical and just pump until bubbles stop? Blasphemy.

Given how tiny the gains and losses are, it's worth noting that if you displayed the entire spectrum of the engine's rpm on your monitor, it would be impossible to tell if there were any differences whatsoever, not just visually, but also viscerally. It's very unlikely that most of the changes made would ever have any real world effects on horsepower, torque and ETs.

[@TheDavidFreiburger]

I’ve tested it three times. It usually gives you 4-5 more numbers in most parts of the curve. Granted you’re not going to feel that, but it all adds up. And there’s zero downside.
