- FULL DYNO RESULTS on this POWER ADDER BBC Stroker. Using a cheap Gen-V 454 core from the junkyard, we built a Multi-Purpose 496 stroker. Using the right combination of parts, we were able to make BIG power then run Power Adders for even more HP! Here in Part 1, we ran the motor NA then with a healthy dose of Nitrous. Part 2 will cover a 6-71 blower and Procharger Centrifugal Supercharger.

It’s so rewarding to see a person like you, with all the experience and knowledge you have, talk this things about cast cranks. Maybe someday the people will learn that even a tire shake can break a crankshaft, but not solely power. Great content as alway!
Big Blocks are the way to go if you want overall power. I eventually want to go with a big block with a huffer on my rat, but I will have to sacrifice a lot of mpg, and a transmission.This is gonna be fun to watch!
That torque and power curve is what dreams are made of. That would have such great street manners, and still be quick.
Just recently found your channel and really like the BBC content. Having been racing close to 40 years and your information closes the loop on a lot of what I've learned in that time. You said you've never seen a crank break just on power... On my "Shelf of Shame" I have a Bill Miller connecting rod attached to a BBC steel crank journal from my first big nitrous engine explosion in my drag boat around 1990 or so. Broke the crank into 3 pieces. Wasn't exactly just due to power, we detonated the motor due to not retarding the timing for the nitrous. I've run N/A, blown alky, blown gas and nitrous. Nitrous is still my favorite power adder. I've been racing drag boats with it since 1988 or so... Keep up the great work!!!
WE'VE SEEN PLENTY GET HURT THAT WAY
“Rev it to the moon”... You speak my language Richard! Lol 😆
I am very excited I have a edelbrock Cross-Ram coming for my twin Turbo 6.0 LS 1971 GS build. Thank you for testing it that helped make the decision.
I've have one also, got it off eBay last year. I think I'm going to try to build a Rat Rod around it, just to be different. Mine is for a Rec port BBC.
That is one sexy as fuck manifold. Not seen it before, but it ticks all the right boxes. Would prefer black over red, but is it normal for a bloke to get so excited over a manifold?
LunarOutlaw’s Garage do you have a link to that video I can't seem to find it.
Dodgy Brothers Engineering I had to go back to the videos th-cam.com/video/gODDOrRKVEs/w-d-xo.html

Really like this video Richard, I have a 72 c10 shortbed with a 496 and a 4 speed and man is that thing fun!
You need your own TV programming. Or better yet, paid well for your content from subs.
You have the best videos. Just sayin.
Thnx-I love what I do
@@richardholdener1727 best way to live your life, love doing what you're doing..
This guy is so prolific I've had to start watching at 1.5x speed. Keep it up Holdener!!
How does this man only have 28k subs ? He's always delivering the goods, A LOT of goods and OFTEN, he deserves better. 👌🏻👍🏻😎
Keep up the good work, my good man. 🤘🏻
Had several big blocks, you are right, they are fun ,little hard on tires 🤠
I’d also love to see some engine building tips/tricks/methods! I know you’ve built a ton of engines over the years and probably have some great info to share
Jfb 1990 there’s tons of tricks to pull extra hp out of a motor
Yes, me too, i would Like tips for building the power he makes without breaking the engine.
Great vid ! pro MAXX stuff is very underrated
Man I feel SO much better now that you’ve confirmed 2 bolts will hold up to 1000hp cuz I’ve been told 700-750hp MAX…mine is very similar to this one but with flat tops and a much larger camshaft (Lunati .680/.700 lift, 296/304 split duration, and 110 LSA). Has 320cc Edelbrock heads and a Brodix 4150 single plane so obviously in the lower 9:1s for compression. Should love the adder though 😏 I’m hoping it’s in the 575-625hp range but we’ll see…always been a nitrous guy but really want to ProCharge this one🤘🏽I know this is a year old but any thoughts on my setup Richard Holdener?!
I had built a 496ci similar to yours. My motor had headers at 2.125 and ran a little more compression. It dynoed above 700. Thank you so much for thi video!! I reallied enjoyed it this!
What cam
love it love it love it!!!!!!!! keep em comin dude!!!! please!!!! quality entertainment!
Two videos in one day! You are spoiling us!
I’m having a 496 built now, filled block, way bigger can, cnc ported brodix bb2 x heads, 13:1 compression, 116 race gas, and a plate up to 600hp lol we’ll see how well the 2 bolt likes it
Nice one Richard. Although I'm enjoying the LS atm i really like the big cube rat motor. Ran a high comp 468 with ported oval port heads in the day.....it did alright. Thx again
Thanks for awsome video Richard. I have built a very similar motor, which is purpose built for nitrous, with forged internals. My motor made 681 hp @ 6800 and 600 ft/lbs @ 5000. On 98 octane. My car is a modified holden hq 1 tonner. ( yes im from Australia.) So after seeing this video i am really excited to finish my project and hit my motor with a 200 shot. I have seen you on motor trend. Again. Awsome video. HOO ROO.
Cast cranks are very strong at first but longevity is where the forged stuff pays off, rpm is what kills rotating assembly parts imo, but you can do some things to make them live longer like increasing rod and main clearance to allow for flex at higher hp, higher rpm
Thanks Richard. Thinking about putting a 496 in my 78 olds omega.
Speaking of heads. My theory is you can never have too big a heads. If the heads flow too much put in a lower duration cam to match the peak rpm you want to run at. Would love to see the comparison in power curves. Take like a big set of Brodix heads and run it with a 212 -224 kind of duration cam vs a set of stock heads with a 275-275 cam.
Too large of a head can make a very lazy port and engine on a street engine.
Scott Worelds never seen it proved on a dyno. Never have I seen someone make a pull on a big flow head that lost bottom end put a smaller cam in to see if the power comes back but stays better up top.
Going to test this theory with my nephew - we have a '97 7.5l(460) BBF on the engine stand that's getting swapped into his Mustang next winter, and we're going to throw a set of Kaase's new bad mofo SR-71 heads on the stock short block(fly cut the pistons if necessary) for the first season with the big block before we build it next winter(or find a good deal on a used race short block w/ an aftermarket block - aluminum would certainly be NICE)
A few years ago, car craft did a test with ported Ls1 heads vs factory ls3 heads. Same cam, truck, camaro and ls2 intake on ls1. Truck and ls3 intake on ls3. The Ls3 was about 20hp up at the top end but more than 20ft lbs down at 3000 rpm and didn't pull ahead till 5k. For the strip, their computer simulated numbers using ls2 vs ls3 intake were within a tenth and 1mph, the ls1 ahead but around town the with the higher torque farther down, the author thought it wouldn't even be close. If you were to put these heads in this test on a 427, they would leave a ton on the table compared to something like a set of edebrock 454-O heads on a street driven engine. The torque difference at 3000rpm would be closer to 40 ft lbs, the camshaft doesn't have the lift to make use of the high flow these heads offer.
On the dyno from tests I've seen on a BBC too much head didn't hurt power, but would it be lazy on the street? Hard to tell that on a dyno. Great call Brian, would like to see a big head with a small-ish cam.
Richard, thanks so much for your knowledge drops in each video. I too was taught the rec port, steel crank and forged parts and a 4 bolt main being the only way to go for power. But found the task daunting when piecing together my first BBC. Thanks for clearing the air on all that. Gunna save me ton of money putting together my build and putting the money in the more important places instead of buying parts I won't ever need for my pump gas boosted build.
This is very similar to the combo I have in my car. Mine is only.030 over making it a 489ci and my compression is 13.8 to1 with afr 335’s, forged crank and H beam rods. Mine made 812 on motor then I have two nitrous kits each capable 400 hp each. The car runs easily in the 8’s. Extremely durable and reliable and I couldn’t be happier.
What cam
@@infamousnova Bullet custom cam, 4-7 swap, lifts are around 805 but I’d have to check the cam card to be exact.

@@infamousnova Solid roller
@@wheels2199 thats sweet, I'd def like to know the duration @ .050
Hey Richard, thanks for this build. Exactly the direction I am heading for my Chevelle. Appreciate the specs as these details are often left out from other build-ups. I really enjoy the help and info you energetically always give. Thanks again!
Need that camshaft # BR -549
Sample sales
Damn I love this channel bet this guy has a shit load of time in the Dyno room as many videos as he has. Love to see some E85 stuff
Awesome!
Keep em coming Richard 👍🏾
Sweet!
Meet a guy on a job had the same 454 bored out made 800 hp n/a. Nice channel. 👌 keep up the great content.
Need that in my dually

@@fascistpedant758 to late to get in the race
I can't wait to see this one thanks Richard Holdener for doing all u do.
Wait a minute!!! A 14.50" stroke crank? Holy Christ, I'd like to see the deck on that block!!! ROFLMFAO!!! 1692ci!!!! HA HA HA!!!
Them scat 9000 crankshafts are the way to go beating on them for years...
I have a 454, from 1994, with oval port heads, and air gap 4bbl intake with 750 Holley, and long tube headers, I have seen a very similar engine that made 330hp and just shy of 500ftlb TQ, I'd say a cam and rockers would make a big difference, it's from a rv, after I got it , I heard it had less than 50k miles, I think it was well worth $400,
yep
Hey Richard, you must have mountains of engines laying around. How about a walk around video of your test engines and what you do once you’re finished with testing on them
I keep testing them
Yeah man!!!
Awesome video as usual!👍🏻👍🏻
I’d like to see you throw a 300-350+++ shot at it and see what happens If it’s gona take all that boost. Why not a big shot ???
Love the show thanks
Oh heck yeah!
Thanks I needed that I'm building a gen v 454.
Put the big jets in it! 😈
The reason you leaned out and I’ve seen this a thousand times with multi stage nos systems stage one goes fine stage two goes nos backfire, when the second stage kicks in the gas demand is instantaneous and the fuel flow has a lag too it which cause you to lean out and nos backfire, single stage systems are your safest option every multi stage system ive ever seen blows up just like that
Not sure this comment applies to the BBC video
What were final jet configurations for the Dominator?
can you start posting the average HP numbers over a range when you do these test instead of only the peak numbers please? Thank you for all the hard work!
You cant read a graph? Everything you want is right there! Hit pause, and figure it out for yourself.
Great video
Can you do a dual plane manifold shot out between - Edelbrock, Weiand, the factory snaw flake intake and the new Brodix dual plane.
Thank you Richard
And it may be a dumb question to a few but I’d love to know the ring gap setting on this build please sir? Thanks!
.007 per 1 inch of bore
Would love to see this motor comparing a set of oval port heads to bigger rectangle port heads. Then to even bigger rectangle port heads
There seems to be a lot of questions about port size.
Great video!
Trying to find out what degree plug wires off the plugs are typically used with a bbc with aftermarket headers
we run 90 degree with long wires under our headers, but some run them on top
What was the calculated compression ratio? How far was the piston in the hole, head gasket thickness,and cc of the chamber?
Yessss we needs details
I believe he said 10 to 1 running it on 91 octane. Not sure about the rest.
Hi Richard, big fan of your articles and videos! I love your comparisons, test and results showing how many different paths to performance enhancement there is! I like the variety of makes and power adders and have believed that engine or car doesn’t know what name it has!
Amongst all I have a weakness for BBC with a power adder.
It would be cool to see how close in performance at ~1-1.2k HP overall power curve would be between compound or combined combinations of power adders. Not which makes more power but more and repeatable power under the curve!
Regardless the path love your articles and videos, good luck and keep up the good work!
Carlos
Wow thats very little timming pulled what comp off motor very good video
Awesome power!
I would really like to see someone do the best power adders for a gen 7 BBC. Since they don't have much aftermarket support. Maybe see how much power adders they can handle before they break.
Awesome video. Nice. I like to see these. I love big blocks. I built a similar one but used forged internals and now I’m mad I spent so much money. Lol. Too bad I sold it before it went in a car.
Sweet. Love this series.
Damn it Richard. I'm a few videos behind. Before we know it, you'll be on Motor Trend on Demand. lol
Never
@@richardholdener1727
You are CORRECT
Call your own shots.
Would love to know what vavle springs you use with the br300.. part number? Thanks again
How 'bout doing all of this with the 8.1 Vortec. In your opinion, would it be worth it. Thank you very much for everything you do for our education.👍
that is a hard motor to find and not much support
Spaghetti rods fold under stock power
Twin turbo power adders? Maybe some e85? That’s considered pump gas right?
Compare the Cadillac 500 and the 454 in nitrous configuration
looking for AFR 3610-1 heads.
So much yes
Awesome
Question ( isn’t it about deflection with a cast crank , not about braking it?)
There is something about the BBC, you might hate Chevy's but you have to respect a BBC.
How long is that cast crank gonna last though?
Hello, @Richard Holdener I wanna build a daily driver pump gas 496 with nitrous and fuel injection. Do you have an email so we can discuss a possible parts list? Thanks in advanced
killerbe16@aol.com
Man I hope one day I can be as smart as you with motors 🥺
What looks better on a big block than the dominator? A 671 blower!
Can we have a part 3 with a screw blower and turbos? Great info as usual!
Anybody else want to see the dyno run from idle on up??? Christ hell man let us see the damn engine performance thru the whole RPM range!!!!!!!!!!!
show me when you run WOT at idle
Sweet street motor‼ you could definitely hurt some LS feelings
Just a curious question, why couldn't you run hydraulic roller lifters on a solid lifter cam?
you can but ramp rates are different, its might be better to do the opposite-solid lifters on hyd cam profile
That damn curve looks like a neck breaker!
How many shots or dyno runs can a tank that size do?
Hi, I have a gen V 454, would like to get it to make 550 horsepower NA. Can you please recommend the parts if need to accomplish that. Thank you in advance .
do a search for gen v build ups-Evan Smith did one with Westech that made that
@@richardholdener1727 thank you Richard, really appreciated he reply ! Love your videos and all the great info . Good job 👍
If you were building a 10:1 496 with Stock 990 heads and could only run a Performer RPM Airgap due to hood clearance what cam would you use? For power under 6500 or 6000. Still the 300BR? Love this build Richard.
There would be better choices-I just like it as an all-around when running NA and boosted and nitrous
@@richardholdener1727 I'm all ears, have this engine going together now, but no cam yet. Open to solid or hydraulic roller. 3000 stall, 68 Chevelle.
Can I get some SBF action? Old school 5L stuff please.
coming-its all coming
TWIN turbos
that comes on the 540
@@richardholdener1727 I'd love to see it on a 468 at 7200 RPM Peak
I want to know what ratio rods you used on this build, and what ratio rockers were used as well.
COMP ALUM ROLLERS AND UNCLEAR ON RATIO RODS?
@@richardholdener1727 sorry, I meant connecting rod length 🤦🏻♂️
Why build a 496 when they are available stock, look for the
8.1L vortec in junk yards, fail to mention BBC are Very Expensive to build!! Any good cheaper Head is $2800.00 for the set..that's why I like the sbc
Gen1 and LS, half the price to build than a big block chevy. Put up some More Gen1 👍
Chevy. Like to see some SBC 's I know it a dying Breed, Ls is Conquering the BBC and The SBC Gen1 era...
Like I've said before you have the best job in the world lol
Richard what head gaskets do you use with the gen 5 block? I’ve read there’s potential for coolant leaking into the valley with a mk4 style head on a gen 5 block, have you ever ran into this issue?
we use Fel Pro gaskets designed for Gen V
Factory gen 4 heads on a gen 5 block can be a problem but all aftermarket heads work fine on a gen 5 block
Would like to see a test with some oval port heads
I tested EVERY Oval and EVERY Rec port BBC head a few years back-I have all that data.
Do we have a link somewhere?
@@richardholdener1727 do you have a link to the data from testing those heads or title to search for the video? I am building a 427 tall deck for my ‘81 c10 project. I am planning to use a 4.25 crank and 4.35 bore to make a 505ci. It’s a budget build so I’m gathering parts as I find good deals. I would love aluminum heads but will most likely have to use GM oval ports for this go around. Thanks for all the great videos!
🗣 STOKA!!
nice...
I wanna see BBF nitrous boost NA pistons and heads rods and cam
Stump puller
So this combo uses stock length rods?
no
Richard Holdener ok thanks
Hey richard, i have a question. I just got a 1970 Nova with a 496 and 2 stage nitrous. Problem is, i know nothing about this. It has a msd ignition, 1150 holley. The problem is it keep missing and fouling out plugs. Do you have any suggestions on what it could be? Im not running the nitrous and my suspicions are that its made to do so. Im wondering if the WOT first stage is retarding the ignition expecting the NOS yet im not using it. Any advice on this would be great
DO YOU HAVE THE SYSTEM ARMED TO ACTIVATE? IF NOT THEN ITS PROBABLY JUST RICH ON THE CARB
@@richardholdener1727 there is a button to arm the nitrous which I have off. I have a msd digital 6 pro. I was just looking up the manual on it and im wondering if the WOT 1st stage is interfering with the timing or something. Or does that typically only effect it when armed? Like I said, I don't know alot about the subject but I'm hoping watching your videos and other will help me. BTW, thank you so much for your fast response! I see what everyone is saying about you
So basically I'm wondering if its retarding the timing expecting nitrous. I dont know if that has anything to do with my problem or not.
What was the compression of the engine? Thanks
10 ISH
@@richardholdener1727 thanks, my 496 is 10.5 to 1. Everyone keeps telling me I can't procharge my engine because of my compression. Do you think it will work out ok? I'm mostly looking to just get to around 800hp
Right but your running on a dyno which is basically no load, run it in a 3800 lb car over and over and over .
The dyno has more load than a 3800-pound car
@richardholdener1727 false, very very false .
Why not test the twin turbo set up on this motor? We would love to see that test
