Vizard has a 496 combo with 236/240* cam and TFS 280 oval port heads. 721 bhp and 711 lb-ft. Your 498 can use an even smaller cam with those big ports (106* LSA).
Used to push barges full of race and jet fuel from one refinery to another 2 miles away, Conoco to citgo lake charles,and they'd add their own additives and sell it... People think every company makes their own fuel,but a lot of them trade back and forth every day.
635 horse is pretty good for an NA motor, even an 8-liter. And it makes like 70-80% peak torque right off idle. That's what ya gotta love about big-displacement American V8's - they're just brute strength in engine form.
I haven't seen nearly any videos regarding engine build testing for this yet but something my father had told me that if you want to make really big power is you need to smooth out the casting surfaces inside the motor for the oil to flow better as well as opening up any return paths . I'd like to see you fellas do a comparison video of 2 identical engines except one has been ported and polished inside and then see what the numbers are then do a tear down inspecting the internals for any signs of wear . I'd also like to note that the same porting and polishing could be done to intake and cylinder heads be as cast or aluminum. maybe do another video comparing a diy port and polish verses off the shelf CNC heads. not sure if cnc intakes exist. Lastly , gasket matching vs not gasket matching the ports. Anyway , these are the other things i'd like to see done. If ya end up doing this , gimme a shout out so i know you saw my comment. Cause as someone whose planning to build an engine i'd love to know if any of the extra work i'm doing prior to assembly is actually worth doing or i am just wasting my time making the insides pretty for nothing. Thanks.
@PowerNationTV. Nice works guys! But I have a genuine challenge for you. Either a GM series 2 3800 S/C of course (but that’s simple) OR a 4.0L L47 NORTHSTAR! The 4.0 is the one with racing pedigree and we all know how Cadillac loves to race. Can you guys build an ITB Indy style DOHC V8. The architecture of the northstar is very similar to the Atlas/family 4200, The same old small/big block builds gets really stale.
A real low end torque motor would be a pleasant experience from this channel, INSTEAD of claiming to build a torque motor and then winding it out to 7000RPM!
Loved the different iterations... Would have loved to have seen what it would have made with a spacer I'm sure a racy engine will get a hood scoop of some sort... Also I think that the hp/tq curve would have looked better/flatter if you would have put the EFI back on, would make tuning it easier, better drivability, better starting, and best of all more power. Just saying 😉
That’s actually incorrect. Carburetors make a squeeze more power. Fuel from a carburetor runs through the intake and cools the intake air making a little bit more power. You don’t get that effect with port injection.
We used to run the mark 4 marine blocks,bored to 468,with tunnel ram 1050's, a glide and big stall,and it ran hard. Once we switched to LS7's though,there was no going back,like night and day.
It's Four hundred& 96ci "big block" American made. Originally a GM 454ci ...different crank and rods, (that you can buy with pistons, in a 454 stroker kit) I dunno if you 😂 were trying to be funny. If you were.... I DONT GET IT, IM SURE NOBODY ELSE BUT A GEARHEAD POSER, ...MIGHT LAUGH, (BUT THEY ARE CONFUSED TOO)...The only V engine anyone is going to find smaller than maybe 160ci (never a 'big block) Is a V Twin
I'm surprised Pat even bothers with ear plugs,cause you know he's old school snd probably can't hear shit lol when i was a kid we raced a 68 camaro,468 tunnel ram, and noone even thought to give us ear protection, and you know it's loud when your eyes vibrate lol
Please build the new 7.3 Godzilla engine ford has. Seen a few different builds already but want to know what it makes NA. Would love to build one and run as a big block dirt modified
Serious question: does no one paint aluminum heads just to show them off? After dealing with aluminum corrosion on my old build, my next engine will be entirely painted- heads and all.
My 'El would love this..but couldnt afford to cover the tax on it. Says solid roller cam but shows hyd roller lifters? Por 15 engine paint is the best! Follow directions guys you screw it up and youre stuck with it. Got thier titanium, great color
An extensive explanation of how a stroker is engineered from the crank,rods,heads,ect. would be nice.I have a good idea of what makes a stroker but not so much how it got there.These shows seem to skim over much of the process
How come mercedes recent 2L turbo engine can make 421HP but this 8.1L chevy engine only makes 650HP? When its consuming like 4 times the amount of fuel
Efficiency. The 2L is a more efficient engine and is therefore able to perform more work in the form of horsepower and torque with less fuel. Sadly this efficiency comes at the cost of simplicity and reliability because of the specific conditions the 2L is designed to operate in.

Have you set your dyno graft for 300rpm? Better graft that way.
Am I eligible to enter being from Canada?
Would look real nice in my 88 C1500, hell I'd even paint match the body to the engine.
When the winner is chosen, will you show proof of them receiving it?
@@NRJracingi agree, i doubt it tho and what do we gotta spend
My 96 caprice would shake the streets with this engine
That 496 will look very good under the hood of my 1969 CST/10 396!!!
I love watching power nation

Love to see the dynos match up! “That means everybody’s stuff is right”
Big block I love you.
Thank you for including the season/episode number in the title.
Great color combo
5.4K+👍's up P N thank you for sharing 😅
That's a mean Mustang with near 1000 at the wheels! Also, can someone install that big block in my Trail Boss? 😂
Definitely drop that into a 79 Coupe de Ville and watch peoples reaction to this one.
"Allsome!" - Frankie
Awesome show guys
I see Junior has a little pocket protector now...😂😂👍👍👍
lmao
I got the best rig for that big 496.... 1971 3 door GMC carryall 3/4ton 4x4 on 37s.... Only 50 were made 😎😁
Simply awesome guy’s 👍🏻
Esses motores são prazerosos só de olhar
That's a gorgeous engine 😍

Great job 👍🇦🇺
13:16 I really like that new color.

I am entered to win. My Nova would love that engine!
Awesome engine guys. Really nice paint job!!!!
Beautiful engine would look beautiful in my stepside 🔥 I need to watch all the videos of this engine
I am entering every chance I can. My '69 Chevelle always needs more power.
Man that 496 would look sweet in my 91 Comanche. It's just a garage Jeep anyways, I go to NAPA and the restaurant now and then just to show off....lol
Hell yeah
This would go solid in a GMT400 platform
Not going to ice the intake i love it!

You guy should build a 366 or 427 tall deck truck engine. I would love to see a stock dyno and modified dyno.
I have a 496 tall deck. It's a monster 👻
I signed up earlier I’m going to manifest this for my stepside 🖤🔥
The 496BBC final form
I have to say, you guys have my dream job.
Great video

I wanna slide this in my 1931 Ford model A. And do wheelies with it leaving cars and coffee 😂
Pat always seems to be intense and anxious. Be kool, relax. 🙂
I gotta have one 🔥🏁 496 that is
Fc from Thailand ❤❤
I need this for my '85 bronco.
Who is worried about low end torque with an 8.1L engine? Go with the RPM build!
A real low end torque motor would be a pleasant experience from this channel, INSTEAD of claiming to build a torque motor and then winding it out to 7000RPM!
tbf you can build a BBC that revs to 7k that makes over 500ft-lbs from 1000rpm up, if thats not a tq monster nothing is@@towgod7985
@@towgod7985 Still makes huge torque down low
Would love to see you guys build an old Ford 534 super duty engine. Could be a hit 😅
Loved the different iterations... Would have loved to have seen what it would have made with a spacer I'm sure a racy engine will get a hood scoop of some sort...

You don’t get that effect with port injection.
@@loganh2233 only peak not average
i pray that Pat will adopt me one day and help me with my v6 mustang ...
I see a sneaky pete bottle behind you Pat. Throw it on quick and see what it can do, lol.
I have one question,why is the LSA so wide?.
For manifold vacuum.
@keithscudder7136 ok
Dusty @ David Vizard built a std bore 496 cast iron cyl. Headed 10.5 to 1 cr ... made 707 hp and 696 tq
I would love that 496 big block. But I'm not that lucky.
I wish I could have put that in my c10
If you change the camshaft it's not the same short block I would think
So 104 centre line . Does that make this cam shaft 8 deg advanced ? Also explain peak hp at 6200?
THAT LOOKS LIKE IT WOULD FIT MY OBS GMC
Sure would look nice under the hood of my truck. Pbly get better mileage than the 4.3 too. lol
I have never seen you guys build a 1000 yet that is my request
gm already does
Great build, but can you do a big block for torque and fuel economy for a suburban ot gas 3/4 pick up
Big block and fuel economy are words that don't work well together. It's the price of displacement.
Shoulda been Chevy orange
where is that accessory drive from?
NOOO..... You broke up the twins!!!!! I wanted to see the out come of timing the cranks... Damn guess the internet will forever bench race the idea.
Will this fit on my 1978 CHEVROLET NOVA, SEDAN?????
Frankie must be learning stuff from the rest of the hosts for the other shows, especially anyone who paints!
Frankie learnt from Pat, how to load his top shirt pocket up to the Max !! lol
How about doing a big block buick
I could use that engine right now
Why such a big cylinder head on that combo?????
My 2006 Silverado came with the 496ci.
What do you guys think of the Raylar kits for the 496ci, 8.1L? If you read the comments?
Im keeping my 496 in the 750hp setup in my 81 camaro i can afford to loose a few ft lbs of torque
That Duralast battery is absolute trash 😂
Yup.
We used to run the mark 4 marine blocks,bored to 468,with tunnel ram 1050's, a glide and big stall,and it ran hard. Once we switched to LS7's though,there was no going back,like night and day.
😂 a 96ci big block huh? That's gonna be a heavy weed eater.
And I thought my 52cc badger was a big weed eater!
@@FastBowtie388it is 😂😂🤟 2 smokes all the way

Is a V Twin
Yep, thats close to1600cc's ... that would be a string trimmer from hell! 😂
I seen that YT update too 😂😂
What RPM was that Mustang making power?
I could be wrong
Is it a stroker as that was a stock size for trucks?
stock block with a stroker kit in it
4.25 stroke and 4.31 bore so it's bored 60 over with striker crank
An 8.2L engine, damn.
😆 I Think everything is gonna be ok , BCUZ OF ... What's going on in Bama 😆 😂 !
I'm surprised Pat even bothers with ear plugs,cause you know he's old school snd probably can't hear shit lol when i was a kid we raced a 68 camaro,468 tunnel ram, and noone even thought to give us ear protection, and you know it's loud when your eyes vibrate lol
and you feel it in your chest
Thought it was gonna be a Geo motor
Please build the new 7.3 Godzilla engine ford has. Seen a few different builds already but want to know what it makes NA. Would love to build one and run as a big block dirt modified

Dust aluminum heads with high temp clear coat. Not real heavy or it will turn yellow. Works fantastic.
How do I get a job working for these guys?
Does Power Nation like Ford , Chevrolet , or ..... Blake likes Ford & Dodge !
💯💯💯💯💯💯
I sure would like to be able to win that engine!!! Unfortunately, not willing to sign over info per the privacy policy statements.
Bummer.
It's amazing how much people don't read that stuff. Or permissions on apps for their phone.
My 'El would love this..but couldnt afford to cover the tax on it.
Says solid roller cam but shows hyd roller lifters? Por 15 engine paint is the best! Follow directions guys you screw it up and youre stuck with it. Got thier titanium, great color
An engine in a paint booth 😂
An extensive explanation of how a stroker is engineered from the crank,rods,heads,ect. would be nice.I have a good idea of what makes a stroker but not so much how it got there.These shows seem to skim over much of the process
That turquoise color has gotta go! I would have blacked it out😜
everyone has a black engine...cant see oil leaks either if its black
@@gordocarboI can spot oil leaks on mines
Not bad for humans!!! 😅😅
Whats up with that massive torque dip at 41/4200 rpm? Thats not cool.
8 degrees advanced?? hmm
They are the heads that cost a fortune
Why doesn't Pat tell jokes anymore? I've gotten some good ones from him
How come mercedes recent 2L turbo engine can make 421HP but this 8.1L chevy engine only makes 650HP? When its consuming like 4 times the amount of fuel
Take the turbo off and then ask
Efficiency. The 2L is a more efficient engine and is therefore able to perform more work in the form of horsepower and torque with less fuel.
Sadly this efficiency comes at the cost of simplicity and reliability because of the specific conditions the 2L is designed to operate in.
👍
"flat torque curve"... Looks like a damn camel.
It varies by 40 lbs/ft over a 3,000 RPM range (3,000 to 6,000). How is that not considered flat? 🤔
A 96 ci big block eh?
I thought this was going to be a special episode with a 1/5 scale v8
I think there's a typo in the name
