Vic 340 build

Thought I would share some pictures of a team build.

This is my CNC program for the heads.
All the billet stuff made in house at Harshman's automotive.
Jermey Hasman did all the billet CNC stuff
Randy Harshman has done the block in his CNC block machine.

Hope to have some Dyno time on it early next week.

Now that is an interesting intake.

Very cool. Beautiful work. Thanks for sharing.

Is that an example of the CNC program that also has a cuttered finish added, or the prototype head that you based your CNC program on?

Do you farm out your seat & guide work?

That intake is unreal...…...

Very cool.
A couple questions....
What size are the intake valves ?
The block is 48 degree...yes ?
Were there any big problems besides push rod clearance ?
Are the rockers common shaft ?
I am guessing that they need to be offset as well as the lifters ?
Finally , do you use Chev bolt pattern on the damper ?
I did with my deal just to open up options for belt driven accessories , but not having the capacity to fab the shiny bits sort of forced my hand.
Sorry.....one more.
Who's cam drive ?
That is really a work of art.

From my master to the 4 sets we got they changed the castings

So I had to hand blend a bunch of stuff in.

We will re-do ports and digitize again🤦‍♂️

I only have stones for valve jobs so yes Randy cuts most of my square seat stuff
All with cutters I pick/design.

2.200" intake
Yes 48°
We started with pro port heads so we did pushrod CNC clearance program.
We cut the common shaft off and had Jesel shafts made (thanks to the Buckner's)
Letting us piggy back off the custom rockers they had made.

We will be changing system up as we can only get 1.8 rockers as of right now.
Cam drive is Jesel.
Yes I always order Chevy front. Be crazy to get Mopar front.

Lifter on intake has to be offset.

We got offset exhaust but really did not need them.

This is a thrash to get on the dyno before PRI.

TTi will sell you just exhaust flange.

Worked out for my ports 😅

Nice work as always. Hope you make your deadline

Nice work Brett, as always.

That intake is killer.👍 Does the exhaust port benefit from that "golfball" finish?

I love all the details Brett, looks killer.

. I agree thanks for sharing your hard work Brett

That looks fantastic

Thanks for the reply.
This is one tasty build.
It's always fun to look over and see what's going on in the deep end of the pool. ;-)

Hey Brett, who is doing the oil pan? Got any pics of the inside?

So you could say this is a max effort deal? lol That looks amazing, are you going to share dyno numbers?

Rough is the new smooth

Should work nice with that MP590 cam

Just wait until that thing meets a .690 cam and its mushroom lifters

Reminds me of the saying one of the head co. used fast as cast.

For sure hope to share dyno numbers as soon as we can

Waiting on a few parts.

And a few more billet parts need made😉

Awesome piece of working art. are you aiming for 2hp/CI ?

are those rough ports really ok ? would that keep the fuel from dropping out of suspension because of turbulence ? remember, i'm the dummy here.

Surface Finnish is so far down on the list of what matters in a cylinder head.

I think maybe you could change what port is doing by a small margin with surface finish.

But most of the time a rough finish will make more power than smooth.

thank you for your response. with a slight "tootsie roll" cleanup, would anything be gained, other than a "good look" to the port ? if i were doing this, it would make me feel good just going over the finish with a 60 or 80 grit roll.

What are the bronze looking spots in the intake and exhaust ports.

you know at 1st I was going to say Valve guide, then I noticed what I think your asking about, in the Exhaust pic it's off to the right side on the wall across from the stem?

the guides perhaps ? that's what i [ahem] ASSumed ......

i just thought that mark was some left over dykem.

Or excess assembly lube from the valve stem.

Do you have the same thoughts on surface finish as Larry Meaux and Chad Speier now?

Other than my CNC stuff I have let carbide finish for years. ( I am no good with sand rolls and no patients for it)

I know Lary has done a good bit of back to back testing and his results show more power with rough finish.

But again finish is way down on the list of important "stuff"

I sand rolled the chambers because I can do them quick and it looks nice. 😂

Should have just left them in carbide.

Some sand roll vs carbide

Thanks. Always interesting to see your work.

Headers should be finished up this weekend for the dyno.

Lenny is working on them. (Owner of the engine)

Do the latest run of heads come with the top four head bolts drilled? Or did you have to do that yourself?

No we did a program for that and Jesel rocker bar attachment.

We hope to be getting RAW castings with HIP process done

Then my buddy can cube them and we will change the stuff we don't like about the heads.

Edelbrock has been un-receptive to changes we would like to have made.

HIP = Hot Isostatic Pressing ???

Yes

Working them Brett hopefully they will turn the corner

Some shined up to head to PRI

Bore stroke?

4.180"
4"

How do these compare to a 'good' W8???

X2!

We are going to see real soon how they stack up👍🏻

Some more billet parts got done today. 😮

Some real nice stuff goin' on here.

^^^ ^^^

What is this engine going in?

Never noticed before but those dual offset lifters kind of stare back at you!

Ahhhhhhh........the song of my people ! ;-)

On Facebook Brett said "She is fighting us.".

Pure speculation on my part but I am guessing it may take a bit to perfect that new manifold and it may be awhile before we see the dyno numbers.

super nice work on that 4 into one hose adapter ! your skills are showing with that !

Beast !!

Wow!!!

AWESOME!

Go find that 7HP!

Great Job Brett!

I've seen some of the stuff Jeremy has done. He's an artist with that machine.

LOL, wrong again.

Impressive numbers but they are looking for more.

image uploading site

Now that is getting it done!

Congrats Brett!

Remember that's an Edelbrock head

Impressive...

Amazing work Brett. Edelbrock Owes you a huge thanks way I see it.. your hard work has proven the idea... with the intake Port height that you have came up with in this head potentially could be a class killer
If someone would step up And try it

I agree with Shiloh, Edelbrock owes you on this one. Maybe, just maybe, they can pull some strings on getting blocks done.

That head and a good block, BINGO!

Maybe an intake manifold? That would help too.

You are making me feel bad about the results I've gotten in the past with both BB and Hemi
Congratulations on your results
That baby is really barking, time to let it eat

I'm not sure what shocks me more, the 1000 HP or how freakin' tall that intake manifold is.

beautiful beast!

What fuel and RC?

Got to love 2.3 HP/CI NA, I know lot of Boosted builds that are not in the 2.3 range , great work.

Nicely done Brett!

Pull to 9000

Impressive!

Any one want to buy my big block?

That's how you make a 2800 pound car.. run 520's

Imagine that bullet in a pipe rack

Stop by T&S Machine at PRI to see this beast in person.

Will have a head to look at also.

Incredible build by all involved! Nice!

Hangin' with Tim and the boys?? Sounds like fun! Tell him Hi.

Does anyone know that this beast is going into?

what's the maintenance on a motor like that?
Awesome job!!

Really maintenance would not be bad on this at all.
Shift at 8500 I am not sure how many passes it would go before it might need springs.

Has 65 pulls on the dyno between 8500 and 9000 rpm.

Springs still check fine.


Rocker ratio only 1.8 intake exhaust 1.75

60mm cam and Jesel keyway lifters are solid parts and should give good service life.

Awesome build Brett as usual. How did you come up with the extinct r3 block?

Got it 3 or so years ago for a guy doing turbo build.

Was in NJ was on eBay

Funny was sold 2 times after that and it's back here and I got to build it 🙃

I was on the Edelbrock stand, it was today or yesterday. One of the Edelbrock guys was showing Herb McCandless around, made a point of showing Herb Brett's ported head. Really talked up the good results and Brett's hard work, and what might happen in the future. Just thought I'd mention it

That's cool to hear.

Did you get to check head out ?

Did you get to see the engine ?

Sorry we did not catch up.

Brett, do you and the Hartzmans have a plan to modify and market these heads in quantity?

There were a few guys I missed,I'll be back at some point.

I went by and checked out your handy work on a few occasions over the three days of the show. I will be telling a good friend about what you're achieving, he's got a few Victor headed engines almost finished. Hopefully I'll convince him to run something with a decent port on his next customers build.

Brett, I might’ve missed it...what compression does this motor have ?

Lenny Knott the CNC machine owner that is cutting the heads has 8 sets on order RAW castings.

This will help us make the changes we want to with out having to fix/re-do what was machined.

The heads will have HIP process done on them also.

When they are ready to go I am sure we will do a group buy or something to get them out into the market.

Did not post that info.

I see your header tubes are in firing order sequence. People are always arguing if it is worth it. I've always believed it helps. Have you noticed much power differences with header primaries that aren't in firing order?
