Merlin 565 Big Block with Richard Holdener

Richard Holdener talks horsepower with a Merlin based 565 big block

[@3800TURBO]

Not happy you didn't put 2 nitrous plates on with the tunnel ram. Lol

[@turbodave231]

That's what I say! Tunnel Ram, 2 Dominators, 2 plate systems. That ought to ROCK!

[@bigredracer7848]

My 565 ci bbc 15 to 1 compression ratio 948 hp 785 tq with 2650 lb car i run 9:06 et at 154 mph

[@bigredracer7848]

During my burnouts I would hit 8,600 RPMs I'll pass to 330ft at the drag strip

[@bigredracer7848]

I need to get a 1250 for my 565 that's what I need to do I'm holding her back with a 1050

[@arodderz]

N/A power.👍

[@scotty362100]

If you are running 9s with 948hp at 2650lbs, you have some serious problems! You either really aren't making 948hp, or you aren't hooking up, or you just don't know how to drive.

[@RegulerShowTV]

scotty362100 C’mon man either way those are some good numbers you gotta respect, once he tunes the suspension just right to hook properly and whatever else may be wrong with the setup, he’ll have an 8 second car.

[@richardholdener1727]

THE WORLD PRODUCT BLOCK WORKED PERFECT 9AS EXPECTED)-BBC POWER!!!!!

[@mgbchuck6527]

565ci BBCs are a sweet set-up, a friend has a full-on race one (16+ to 1 comp., '900" lift cam, 1450 Carb. ,ProFiler heads&intake) it made 1160HP on Panellas Dyno N/A (works well in his S/C-T/D)

[@daveday3770]

What as the rpm on your motor ,sounds like a pretty wild combo ,you probably can turn over 9000 rpm .I had a 69 copo camaro that I could hit 10,000 rpm with but it had a short stoke zl-1 rotatating assembly ,took me long time to get it like that ,was shifting at 7800 for a long time but only had a 8000 tach and a heavy 38 lb flywheel .took the heavy flywheel out and replace d with 26 lb wheel ,should have used light 11' aluminum wheel

[@strokermaverick]

I’m a Ford guy, but this 565 BBC, is NICE!

I'll take 2 big hair dryers and fuel injection on my 565 please. 😎😎👍👍👊👊✌✌

[@stevenboyle6924]

Richard Holdener is the best!

[@danmyers9372]

Man, that is a lot of power out of a pump gas NA 565. Shows what can be done with really good heads and a big cam. Have to wonder how streetable (why else make a pump gas engine?) it would be with all the valve spring it would take to control a cam that big.

[@racecitypatriot5017]

I got a buddy that got same setup buy more compression. Kills valve spring

[@travisabrahamson5092]

C16 isnt exactly pump gas lol

[@zxtenn]

You sure build some SICK motors Richard, if i ever win the lottery i will buy a 67-69 RS Camaro and build an engine close to that to relive my youth and realize how slow my 67 RS 427/425 with 456 gears and a 4 speed is compared to these space age engines

[@robertelmo7736]

Makes 850hp so now it's time to add some nitrous...I hate you lol...

[@arodderz]

lol...

[@Texasknowhow]

How does anyone dislike this!!??? I’ve always been a small block guy, but it’s a whole new world with that much displacement and NA to boot. Nice video.

[@andrewbieger5004]

NIIICE "little" motor you got there, for sure. I looked at this three times and I swear you are using a piece of wood for carb spacers at 09:28? Do you get more power with oak or pine? ;)

[@RegulerShowTV]

Lmfao I was like “is that fuckin wood?” glad I’m not the only one.

[@TwoJakesAdventures]

Laugh if you will . A lot of big pro stock engines used wood years ago .

[@jbaker8871]

Yes wood is common for carb spacer. Prostock, sonny lenard pretty much any body who ever knew how to build motors and make power.

[@andrewbieger5004]

@@TwoJakesAdventures Whatever works, just didn't know it did. I know that I could fabricate a spacer much quicker with a Dremel tool and a router using wood. I don't have a machine shop but serious woodworking tools .

[@gordocarbo]

@@andrewbieger5004 wood absorbs heat big time. Guys would use wooden laundry pins all over their fuel lines back in the day it really works.

[@sillyguy9828]

What about nos on the tunnel ram. Two plates would be awesome

[@RJZJR1]

With the right Big block you can change Earth rotation... Lol

[@richardcontinijr9661]

At that point I'd look into a dry sump oil system to see if it would free up power

[@ac13apollolee77]

Back in the day the scorpion with the side ways carb they had more equal runner length just a thought from the BLOODY KNUCKLE

[@lallinnBESTI]

So this is the motor, that can fit a Tesla in each cylinder ! There’s No Replacement for Displacement :-)

[@SealofPerfection]

Damn near a $5000 set of heads, but they surely produce the power.

[@johnstewart3937]

Great job might have been to much carb on the tunnel ram for that hp causing a week signal to the carbs and not enough velocity to pull the fuel in, but you and Brule are great.Keep it up.

[@b.c4066]

Lmfao, in the subtitle it said "big black Chevies" I agree, Chevy orange sucks. They look great in black and aluminum

[@DuneWest]

My friend has a pair of 565cid 9.4 comp ratio, meticulously/completely blueprinted/balanced engines for a marine/boat app, w/AFR 315cc cnc'd heads with a little more massaging work to the exhaust ports, some small/mild Comp Cams solid "low shock" roller cams around 250*/.650" lift on 114* LSA, single plane Weiand Track Warrior intake manifolds massaged and "burr ported", roughly 1000cfm 4150 sized carbs should be some pretty heavy duty torque creations to move a 10,000+ lbs boat

[@tomwhite9034]

I can't believe that somehow I missed the bloody video lol but I'll catch up

[@robnordal1906]

Throwing the kitchen sink at it!!! LMFAO 🤣🤣🤣🤣 good one!!!

[@shannonbunch1003]

Absolutely love the engine... I'm guessing this engine, minus assembling , just the parts is about $10,000. Bracket racing engines generally this size ( 900 to 1000hp not assembled can cost over $13,000... Shafiroff racing puts them to together but there damn near $20,000

[@roggiepettaway6275]

Mine cost me 12.5k but I bought the heads (Dart Pro 1) and the carb (Holley dom 1250cfm)

[@MsDimov]

what if u try itb's with electronic injection? What numbers motor can show on the dune?

[@garymathews4042]

you can buy a great BBC built short block for under $6000.

[@GaryWhipple-q6w]

Think that Dyno is alittle generous

[@airfancon]

How many degrees of timing?

[@rayfoxworth2360]

Big block Chevrolet is the way to go

[@wallywire]

Like that moroso oil pan.

[@Syrus54]

Put your mic closer to your face, and turn down the sensitivity.

[@bure4me]

RH, have you ever run back to back nitrous tests where the change was heads flow? Example. Does a 150-2000 shot net the same result when tested on and engine where head option 1 flows 30-40 cfm less air than head option 2?

[@s1914]

Fascinating

[@gordocarbo]

This bore/stroke combo makes this the ultimate BB for me. Its having to re do another trans rearend etc that would kill me . That would shred my built 12 bolt and stage 2 T56 to shreds Unreal!!

[@stevekotenberg133]

what size headers?

[@kamcisneros3544]

Soo good, great video Richard

[@carrilloford]

Love that bottom end.

[@willkincaid5841]

This channel and others like it proves that the " word of mouth" in some ways for power adders or even just small things that can make good or decent power, all the little things add up! You just have to do your research. I quit listening to oh you shouldn't do that or run this when I swaped and boosted my car I ran it with turbo maxed out on boost and a few other tricks, the engine lasted your 6 years before it got refreshed. But I bought it used also, and did all my own work/ prep work before i stuck the swap in.

[@broz1969]

Richard, were you guys running a rocker stud gridle? Pictures dont show one, but I wondering if if did do to the large cam lift.

[@ckane510]

Split doms staggered would have helped your lean condition. That’s what there for.

[@willkincaid5841]

Thanks Richard, I've always wanted to get my hands on one of those Merlin blocks or a assembled one. I've got friends that ran them and they were bullit proof. It surprised me to see you cranked that think to 7500 but after I saw what all was done I figured it out haha. But awesome video. I would love to have that engine but I also know you probably have a good chunk of money in that thing. I'd like to see a pro charger on it or a turbo charger maybe. I'm more of a turbo guy cause you can always turn the boost up with ease. If you have the proper turbo that is. That would be a good video to do if you haven't. I know that would take alot of time and money just throwing that out there. But if you have awesome! Thanks for the awesome videos. I really love how the nitrous plate made power with no N02. I'm gonna watch it again and try to figure that one out. Keep up the amazing work.

[@klausvonschmit4722]

Awesome video! One of my favorite times when I could race was the two days I spent at westec in the company of the greatest horsepower making machines Steve and Stiregal Dynoing my 572 BBC BG deals that needed more air! 🤣 an awesome experience to sit and just listen and do everything they said to do

[@davidder4516]

Michigan dude over here just dreaming of having that power and knowledge . I got some knowledge but not like this guy well mabe some day tho . Love learning new tricks and tips and actually seeing what does and doesn't work on real world stuff makes things easier .

[@adrianlancione7871]

Great video lots of things too think about would like too know how well it would run on e85 and also for my new 555 build I’m going too run an Elderbrook pro flow XT Ruth a 102mm throttle body have you done testing with this manifold

[@james10739]

Well if it fits that like the first time I think the cost of an intake is worth it but you also need another carb but what was that like 50 hp and foot pounds lie everywhere

[@rjones2000r]

Makes me wonder about all the tricks that go into a 500ci pro stock motor that puts out 1,400+ hp running n/a

[@keefespencer1173]

On top of the 8 O2 sensors in there you should've also put a set of EGT's in there as well and a fogger kit on the tunnel ram and 2 nitrous big shot plates that you can jet up to a 500 shot a piece and have them wired to hit at the same time together I personally have never seen someone run 2 plates on a tunnel ram plus a fogger and if you can get the engine to put out anywhere from 1000-1100hp N/A plus all that nitrous you could potentially have an engine that is making 2000+hp where most of the time guys who make that much hp have a 632cid engine with 3 kits

I like BBC and I would like to see you do something with an 366 tall deck just for curiosity

[@ze_german2921]

WHY not a 632ci. ? Isn't the rotating assembly about the same cost? If I was gonna build a big inch BBC, if it is the same money upfront, WHY not? 😊

[@robnordal1906]

Good old fashioned torker intake from EDELBROCK.

[@ERIC4624]

why didn't you just go 632??

[@yarrdayarrdayarrda]

we've only found about 10 to 15 HP gain with the Q-16, even with over 13:1. Only once did we see zero gain, it was on a flathead Ford.

[@garypic4083]

Did you really do any of this or are you just reading somebodys work

[@dalegroves1918]

To build this motor in parts alone would be over 12 grand and by next year a loaf of bread will be 10 dollars. Great video.

[@MMWelding_]

Even though it’s a pump gas motor how do you think it would be in the streets cooling wise?

[@grumpysteelman]

Why would it be an issue? Obviously heavy duty cooling - a 4” deep radiator core and running an electric water pump or standard to slight overdrive on the water pump would be a good idea, but a big block with a cam that isn’t causing it to load up at idle shouldn’t be too hard to keep cool. I’m not being intentionally obtuse, because most BBC application have less room in the engine bay but the major cooling “culprit” is long tube headers increasing the engine bay temperature on most combos.

[@morley3810]

I’m sure you’ve done it...and it’s totally unrelated to this video...but I’d be curious about the actual power gains from various kinds of valve cuts. Stock, 3 angle, 5 angle, full radius etc. Specifically on a 6.0 in a Express Van with 706/862 heads and a small cam. Like a comp 212/218 etc. Is it worth it to get the valve work done or just run the junkyard heads as-is?

[@gordocarbo]

Hes done vids like that. absolutely get the valve job theres power to be had there. 15-25 cfm easily! DOnt grind the daylights out of the valve like you see guys doing thats backwards

No more Merlin blocks for me, I have a four link Miller dragster that I bought used with a 565 on methanol. It was built with a Merlin III block and wound up cracking in the main webbing, The Merlin blocks have a history of this and was supposed to be fixed with the updated Merlin III. I’m right now trying to get the 565 put back together but I went with a Dart block with a rotating assembly from Ohio Crank.

[@gordocarbo]

OUch$$ Dart makes good stuff hope shes running soon. Wish I could afford to build one!
