[@sstevocamaro]

I like the fact they tested it with full accessories! It’s hard to find dyno testing like that!

[@KingJT80]

they do it with baja big blocks that make this level of power but way more $$$$$

[@MerlinOpeth]

Pats a boss

[@AB-80X]

No it is not. But why would you waste money on it? Most of us who dyno do it to tune and/or diagnose. After a while you know exactly how much power each type of accessory robs. If you want to talk ACTUAL important factors think water temps and correction factors.

[@ted4719]

The 7.3 Godzilla HP numbers are with the accessories. Take them off it's 500hp ish

[@bradleymadosh911]

Love big block Chevy engines.

[@lagoonrd4173]

His full chest pockets of pens is impressive 😂😂

[@gilbertnaranjo6233]

Think I would have made it 11.5:1 compression. Aluminum heads drop the compression ration almost a full point and fuel injection timing helps compensate for detonation issues.

[@teknoaija1762]

Really nice stuff for bbc s.I raced around the millennium retiring 2007.But that is how it goes.I bought new Dart Pro 1 345 cc heads and with 8-71 my 100% streetable Malibu SS and cruised that around with occasional 9.624/142.945 mph.That was driven with M/T 18.5/15/33 and on airfield track.2004 I built a 538 bbc based on an old 90 s pro stock engine and 360 cc heads+the old blower.It was really enjoyable on the streets as it was so humble and appeared to have some torque.So,to track? we went and totally fried the converter!It smoked like steam engine in the starting 300 ft boiling tranny fluids and still managed to go 9.80 s.I bought a new converter which was far too rigid,of course.During the winter managed to find a nice 526 bbc with JE pistons and Brooks B-2 billet rods.Also acquired a 12-71 Magnesium Teflon stripped blower.Just out of curiosity assembled the engine without the blower and it went 9.922/141.702 NA. I also bought used Hoosier 22.5/15/34.5 slicks and stuffed them in my Malibu and I recorded 1.46 60 footers on normal virgin asphalt.That was quite nice as I terrorized local motor cycles in traffic lights.I remember one Hayabusa guy who just could not believe he was gaptized by old "Yankee" car.I retired in 2008 and sold Malibu to my friends who had been fans since mid 90 s.We had plans to make it really fast as there were 4 guys to pay for that but unfortunately this project has been dragging on ever since.

[@NAPAuniversalJoints]

Honestly the first build with 600 hp and 630tq was a better build for a street car and would be faster in anything other than a fully dedicated drag car

[@user-xt3ot1xu1b]

yep and you get an extra 50 lb feet of tq

Love watching you guys, good team..... More high rpm how 2's please!!!!!!!

[@dustinmarquis5884]

I would love to see a high rpm build. 10k rpm. I think that would sound amazing. Plus to see all the parts and precision needed for that.

[@PerformanceEngines]

pro stock. 100k build

[@jondahl3173]

I'd settle for 8k rpm 496 build...it would be fun...and loud!

[@v8trikebyers756]

Thank you for giving me my dose of horsepower

[@arturozarate1752]

Good job! I'm a huge fan of the 4500 throttle bodies for the Terminator and the Super Sniper. Now if they made a nice dropped base air cleaner assembly for these huge things.....that would be something.

[@kerrymarshall2071]

Now that's an engine I really want

[@stevesolo16]

The Super Sniper will handle up to 1500 hp, but building a N/A BBC that MAKES 1500 hp is not so easy, or cheap. What I would like to see is a 496 set up for a top of the line Brodix SR20 or Brodix BRX(same thing) head or AFR Magnum 18 degree and see how it compares. These heads are quite expensive, so let's rock your Dyno!

[@marlobreding7402]

Once upon a time I had a 1969 GTO that had a dealer installed 428. It was what they called The Royal Bobcat if it was on it Royal Pontiac. They claim to have 375 horsepower Hot Rod Magazine said tri-north of 500 horsepower. I would love it if you guys could find one and bring it to stock specs and Dyno and see what happened. Then Advance the cam timing and see what happens that woke mine up beyond what it already was. I used to Cloyes True Roller timing chain set and just Advance the cam timing at the crank 4°. That made that thing come more alive out of the hole.

[@gordocarbo]

They probably couldnt do it...they would need to buy the parts and hardly any aftermarket support who sponsors these shows. Wish these types of channels would use some good old school cam mfrs...not a fan of Comp Cams. Here in Ca we have Isky and Crower who are top notch imo

[@marlobreding7402]

@@gordocarbo I grew up in Culver City,

[@Joebro200]

Man, these big block builds that spin to 7K must be the best on the street. Not too crazy in the torque department, so you shouldn’t spin off the line if you’re suspension is dialed and you’re running a decent size tire. And you’ll just keep pulling all the way to 7,000. This would be an awesome engine in a street car. I had a 468 big block once in a 1970 el Camino and a friend with a pretty wild 347 engine in a 68 mustang would always pull away from me in a race. He just made power up high really well and my motor was all torque. Made me want to build a big block that spun like a small block. Best of both worlds

[@gordocarbo]

454 4 bolt block or 502? Smaller crank solid lift cam. Real good cyl head

[@blakebusbee-fg9dt]

THE BEST SHOW on Planet earth !

[@MrChevelle83]

My 70 chevelle and tremec TKX would love this engine!!!!! good to know all id have to do is bolt a pile of expensive off the shelf parts together and print the dyno sheet from powernation! NO testing needed! ha!

[@m.s.patrick2863]

I see London, I see France I see a cracked block due to overtightened oil pan bolts. 8:07. I really hope that's a dribble of BLK RTV. thanks for all the content!!

[@gordocarbo]

Probably is. I got freaked out by something similar bolting up my 12 bolt cover. Casting flaw Not sure a BB can crack from an oil pan bolt Id thnk it would strip first?

I’ve made comments about not needing to tell us all these crazy specs but I know realize you do it just in case someone wants to copy what you’re doing and they know what to order and to teach people like me who know but really don’t understand some of the stuff. Amazing video and thank you for many years of entertainment.

You guys ever do the over the cam auxilery oiler mod, wher you tap into the oil gallery near the timing gear and run a thin tube alongside the oil return holes in the valley so that oil drips ontop of every cam lobe .?

[@user-ez9ct2yi2v]

Pat is the Man! Frankie maybe someday.

[@ZONES89RS]

These days I don’t see a 496 like that as worth it. LS engines out there making that much on pump gas should steer someone to do a 565 big block since you are already doing expensive big block stuff. Would be 850 HP if done right

[@kipphawley4514]

You two guys really rock.but it would be perfect. It's cool to see you guys get a project with a big Block International Harvester pickup truck engine. As where have it supedup old School. Like it was during the early days of the 70s and 80s! See how much Hores power is capable of doing. Due to those types of engines are interchangeable with Ford parts.

[@albertgaspar627]

unfortunately they were designed for low RPM torque, and this show deals with aftermarket parts to bolt on. You'd be better off stroking a Ford 460, easy enough to find one with a roller lifter setup already in the valley (that would save over a $1,000 trying to convert an old Cornbinder to roller lifters)

[@Lightning546]

I'd love to see what performance gains you guys could get with the Ford, 2023, 6.7L power stroke diesel.

[@michaelbefumo-qg7ji]

That's pulling alot of rpm fine if was mine i probably stay at 6800 protect my investment, but that was awesome

[@6426yy]

Would have been nice to see the 320 heads with the solid roller and other intake first.

[@GJ-DT]

And carb

check out the GM 502 HT crate engine I have one in a 1985 K30 with a tremec TR4050 pulls amazing.

[@jaybramble2029]

Why didn't you use the AFR 290 oval...would give a lot more power guaranteed.

[@gordocarbo]

Torque would be improved for sure. Skipped to the dyno part soon as i saw the tq numbers I figured they were no name 320cc china heads

[@johnbehneman1546]

WOW!!! I LOVE THE NEW HOLLEY THROTTLE BODY!!!! SO BADASS!!! I LOVE IT!!!

[@letsride2057]

At 8:07 just above the socket on the pan bolt it looks like the block is cracked. I asked a vintage trans am car owner why Traco painted there motor what looked like off white. He told me it showed oil leaks and cracks the best. I see that now.

[@carguybikeguy]

This thing needs to go into the Caprice.

Not sure how good a hood scoop will look on a pump gas muscle car, but the horsepower output of the engine is not too shabby 👍

Crazy the amount of rust in that little of run time y’all did dyno setup should have some kind of coolant in them to prevent that instead of running city water inside them blocks

Please for the PONTIAC MANIACS build a Butler Performance IAII Aluminum or cast iron Block NA engine for us you know you want to! 😉. Use all the best forged crank, pistons, alum heads, cam, lifters etc. to build it with fuel injection or carb, doesn't matter to me I'm an old school PONTIAC MANIAC since the 70's💪 P.S. Been a big fan of the show since the 90's with Joe Elmore and Chuck Hanson on HOT ROD TV💯👏

[@dalemckenzie2279]

Nah ... There guys couldn't have that ? They are big GM guys so they'll never have a fair matchup it'll be like the 454 vs 460 match where the 454 had all out top shelf stuff but the 460 had mild upgrades and like the 512 mopar that they built really mild and only made a little over 500 hp.

[@MMCGRACING]

I’m have a similar setup but in need of a camshaft, what is the part number for the soild roller from comp I don’t see it in the description? Only difference is I’m running the dart 360 heads

[@mdtransmissionspecialties]

Hell yeah!

[@bigcountrysgarage2.030]

[@shawnmcatee895]

Im wondering if you requested that cam with a 110 LSA? I'm running an almost identical Comp. in a 501 (4.6B/3.766S) Dart BBC with Dart 345 Pro1 heads in my race boat. But I'm running custom RaceTech pistons that with a 48cc dome for a 13.2:1 CR. I made just short of 800hp and over 600 fllbs from 2800 to 7400. But my cam card showed 108 LSA. I'm running a Edelbrock 454R manifold.

[@user-zd9ex2bn7q]

That's a lot of spring for that cam

[@royduenas1192]

There seems to be a crack in the block as shown 8:07 minutes into in the video. I'm just wondering if this crack would be a cause for concern in the longevity of the engine life. Either way, I always enjoy watching these videos. Keep em coming! 💯

[@teto6912]

Imagine putting this monster in 1 Tone car 🥶

[@KensGarage.]

I want to get the mid mount accessory drive for my 454

[@sargepent9815]

Only thing that I'd have added to push that engine even harder would have been forged pistons, but those aren't practical for a driver car but that would have let them wind her up closer to 8000rpm without the real fear she'd rip a piston apart

[@schmitty_luv]

Next up would be a high rpm 632 with aluminum rods cnc cylinder heads and jezel belt drive with 290degree duration and put it in a daily driver with a traction control system😅 (I have a daily driver if your interested in donating) …….. would be great to see total price breakdowns /comparisons would be even more impressive if everyone could have a big block daily driver vehicle.

I just can’t help it but when I here “lb ft “ of torque I think of Fred Flintstone driving to to work in the morning.

[@yodawunn6700]

At what point would you say a rev kit would be necessary? It seems you rarely see them used at all anymore. Maybe with the spring technology and cam profile designs, rev kits aren't as needed anymore.

[@dexterplant778]

So I gotta ask, did you guy's change the distributor drive gear to a bronze one?

[@user-nc3hh3nn8n]

Pretty decent build. I feel it could have made even more power and at a lower rpm with a better head and a head better matched for the cubic inch, such as a dart or afr 335. In addition to a little tweak in the cam profile... Nonetheless it was a nice build!

[@anhiirr]

depends to me, id take streetability with a slightly "mild" tune vs something a bit more ideal for the pure drag strip use...also that build would be gutted/tubbed etc...id consider a slight sacrifice to torque even peak torque...to possibly bring the power numbers lower into the RPM range. But an outright classic/heavier car, im more or less happy with sacrifices to peak power/power range so long as torque is 'streetable' or a more or less fun/streetable type tune. To me it mostly comes down to end user preference, be it drag strip/auto/rear gears, or manual owners that are tuning more for the rpm/torque range they expect to maximize their fun in.
