393 cid Small Block Ford w/ Hemi Heads 

Greg Brown is brilliant. Not only is he a great engine builder, he’s a first class individual as well. He’s also very meticulous. He built for me what typically would have been a pretty ordinary ~750 hp street 496 bbc. It made just over 850 hp, due to the attention to detail by Greg. Hammerhead Performance Engines is the real deal.

Excellent. Good to see SBF perspective.

It's amazing that you can take an almost 60 year old design, and put it through a test like this, the SBF is so over looked from a design stand point other than it's cast iron design, and two bolt main, it's base design could easily exist in today's modern cars.

Am I wrong, but I'm just sure that Jon Kaase won one of the original engine masters with a 10.5" deck height 351/400M at around 400 inches? Yes, it was 2008.

The ultimate Ford small block .Kudos🔧

I like 👍🏽 them heads. Makes me want to build a Dart 🎯 block

great engineering Mr Brown 🥂👀 . Love this motor ! Thank You 🏁 . Mike Brown

It's been said, there will always be a need for a great engine builder!

4" bore is the sweet spot for flame travel when you study the thermal dynamics

1st Class Hammerhead!

This would be perfect for a turbo small block Ford set up

A FODGE or A FEMI?? Win - Win!! And BTW, The Legendary MICKEY THOMPSON did this to the 427 FE In The Sixties!! He'd Be PROUD.😉🇺🇸🇺🇸👍👍

What a jewel of an engine .

Wow I want this engine in my foxbody. It would be first of its kind

Identical bore and stroke to a 392 Chrysler ( 4.0 x 3.9 ). The 392 ( all of the early engine series ) Chrysler is designed around the requirements of the valvetrain to actuate the rocker arms reliably ( lifter and pushrod angles ). Retrofitting existing inline valve engines to an opposed valve head is usually difficult . It sounds like this may be a success story.

Look for Project Mixed Up Boss…

A link to Brown & Hammerhead would've been nice...

About 2004- 05, Cadillac was experimenting with a "twin cam in block" engine on a V8. It looked tasty and would very easily lent itself to independent cam phasing. Any deeper dive on that engine? FR

This motor combo is awesome....interested

Thank you for your knowledge and video's USA 🇺🇸

not bad pretty bad ass engine

Good job Greg!

Awesome 👍 Build guys great job

🏁👍🥂perfact ! Mr Brown👍 🏁

M400 was kicking ass for a while

I would expect an engine with heads that cost as much as a good crate engine would perform well.

I'd be interested in seeing how Higgins heads and intake would do on the same lower combination.

IM A FORD SVT 460 WINDSOR SHORT BLOCK THESE HEADS WOULD TOP IT OFF NICE

I wish I would have known about the 2018 contest. I live 30min south of Charlotte!

I wish someone like Kasse (or someone like that) would do a Jeep 4.0 head.

Great engine!

It would be awesome if Engine Masters had a class for your younger everyday guys like 30yo max and everyone has to build the same motor like a 350 or a 5.3s N/A with a 383 max ci, carb or efi with all off the shelf parts no crazy exotic or billet stuff, no extra cnc porting on the heads only hand porting, fuel is kinda tuff to pick a fuel so I would say anything but m5 and m3 so if you run alcohol m1 is your only choice. have some body to check the parts and and give the guys and gals 3 days to assemble it, so you basically show up with your block & parts and plan of attack and throw it together and party! it would be awesome to run turbo,blower and nitrous setups but in a dyno competition like that it would be a pain in the ass and take for ever to setup and run several different turbo motors on the dyno, the only power adders that would be easier to get on and off the dyno would be screw/roots blowers and nitrous Maybe centrifugal but that's not fair for us turbo guys

I always believed the Ford engine was the better engine

Mopar style heads. Mopar .904 lifters and Mopar style long rods. All great ideas!

At what RPM was the 775 HP made? Thanks

Cool!

Show us how Jon Kaase got that SBC Tunnel ram to work on that Ford Y Block. I would like to look at the intake adapter spacers.

Small Block Ford is not a term people use because it’s not specific enough, due to the Windsor or Cleveland thing.

Show us the heads !

There must have been some other limitations in the rules. Maybe cam lift ? Or comp. ratio ? Don't take this the wrong way when I say that 770 mark is not all that. I have friend that did a 383 ci Boss 351. And it used the Boss 351 4 bolt block. It was bored and stroked to 383ci. The combo takes care of the rod to stroke ratio in the Clev. The bottom halve of the water jackets were filled in to strengthen up the block. They used the D1 Boss 351 castings. Raised the exhaust floor and ran a Hogan sheet metal intake . CR. was over 14- 1. Big custom ground Lunatic Roller. On race gas it made over 920hp @9400 rpm. My friend worked for Dick Maskin @ Dart products in Troy Mi. No hemi heads, and less cid. So there must have been other limitations we aren't privy to. I'm very curious as to the flow # on those hemi heads. Because I know what those D1 heads flowed. Those are the cast iron models to which the C3 Yates heads came from. Not hard to See 320 cfm on the intake ex. Will roll 242 cfm with out a lot of massaging.

We have one built for nitrous and it made 1030 on motor

That’s really badass. Did he mention the compression ratio?

Bad ass!

Is it Street-able ?

Look up Quiet Riot mustang videos… to see it run

Are you producing your engines for the public to purchase.

i was under the thought a true hemi had the spark plug in between the valves in the center of the cylinder / true top of cylinder?

How much is a set of them heads

I would like to see that Australian 351 Cleveland the 1000 horsepower 1

hemi head is that 351/460 bolt pattern

got a question for u ..i got a 1990 k5 blazer 700r trans 2000 to 2400 torque converter in it and im thinking about buying this race motor it has 12.5 to 1 sbc 355 030 over with elgin e-1090p solid flat tappet cam with scorpion 1.6 rockers for total lift of 573intake 594 exhust can i use the torque converter i have on this engine,,..i no i got alot of things to change because it is a tbi fuel injection

What is the cost per HP for this engine?

welp...anyone heard of a Ford Clevor V8:Ford Windsor v8 block with Ford Cleveland v8 (canted valve) heads??...yhmv..

There is a reason people make hemi heads for most all wedge engines... but no wedge heads for hemis

WHHHHAT?? My buddy built a 400-in Ford that made 800 horsepower and they werent some one-off crazy heads

Ford had hemi heads years ago ..just could not call them hemi

he left jon kaase, makes sense.

Where do you buy those heads?

Q T Thanks

Ewfah! 🧐..😳👍

why is Chrystal hosting a carguy show? is she a mechanic or something relevant?

Three five one lol.

Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party and Gretas FFF Inc. gave order to shorten fuel supply from 2025 on by reducing petrol stations to only one state operated central gas station per city. From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime. so beware of expensive cars today they will be forbidden and worthless tomorrow!!!! :-(((

They are not hemi heads.

Who is the Blue eyed cutie?

1.97hp/ci is not impressive especially with those being hemi heads. You can make that easy these days.

Ew

He "developed" a Chrysler "Gen 3" (5.7 and 6.4 liter) "Hemi" head that fits on a "Ford small-block" with a 350 Chevy bore size which is a damn sight easier than it sounds since the bore centers are within a quarter inch of each other. If only that "small block Ford" had the wall thickness to go another .090" over he could have "destroked" that "Ford Hemi" to 3.76" and built a real 6.4 Hemi "clone". 4 head bolts/studs per cylinder and 4 inch bores and 4.25-4.50 bore-center "small blocks" due tend to result in lots of "race engines" in that "400 cubic inch area" especially given that "real" race engines that have to produce real high performance for hours rather than minutes or seconds at a time are ALL "small blocks". And that included Ford's supposed "big-block" 427 engines at Le Mans when "Ford beat Ferrari" with a "big-block Ford" that like ALL "big-block Fords" EVER had/has "small-block" combustion chamber volume. At least CHEVY small-block "truck motor" combustion chamber volume. Meaning in that "70cc area". Jon Kaase and anyone he has ever "mentored" are GREAT at "developing" ways to apply "Brand X" (i.e. the "competition" at the other two of the "Big 3") engine technology and components and architecture and...engineering to "Ford" engines WHILE "creatively interpreting" the "rules" and "beating" the "competion" that typically and traditionally is...or rather was..."mom and pop" engine shops and/or "college kids" looking to "make a name for themselves" in legitimate competition with time and money and technology "budgets" and "creative license" not one tenth as "generous" of Kaase and whatever supposed "customer" he claims his "build" is intended for the "street car" of. His "Ford Y-block" with more "Chevy" in and on it started breaking the camel's back and his "Ford MEL" so-called "build" with "in cylinder combustion chambers" (his attempt to "clone" the Chevy "Mark 1" big-block 348's "flat head" - no chamber in the head at all - and "wedge" chamber in the cylinder "architecture" as the 348 and 409 were the first naturally-aspirated automobile engines in history to make "1 hp per cubic inch") was the straw that shattered its back and LONG after that assclown should have "retired" from what was ALWAYS intended to be an "amateur engine builder" competition.

Lol. Pretty cool. But hilarious that he basically just turned it into a Dodge engine. Hemi heads and .904 dodge lifters.

Not a real hemi unless it has hemi pistons also

Woke.....
