The Best "AS" Cast Small block Ford Cylinder head ever!!! MIXED UP BOSS 3 years later.. My Review

[@68nitrostang]

It’s the flow at .4 -5 I’m impressed with

[@edsmachine93]

Good recap Andy. The Hammerhead cylinder heads are very nice heads. The valve train is impressive. Thanks for sharing. Take care, Ed.

[@pauljanssen7594]

I think that hood lamp was really important ☺️ nice to see a good rocket I'd like to know what it does at the drag strip quarter mile.

[@johnelliott7375]

Another Magic and enjoyable video and I will pass it on down the road. 4:45 am is a little early for waking up everyone but don't worry they are going to get the bell.

[@outlawbillionairez9780]

Andy, I agree around 800hp is doable, just hard to maintain drivability. I wonder what the intake velocity looks like at partial throttle. Nice review 👍

[@markdudum-ji9mx]

HEY ANDY YOU DID A GREAT JOB BUILDING MIXED UP BOSS AND THEN PUTTING IT IN YOUR 71 FORD TRUCK, I AM IMPRESSED MY FRIEND. I AM A FORD FINNANTIC AND I TOO DRAG RACED A FORD (torino gt) and i too built the 351c on a budget as well as i got about 475hp on the dyno of cource i had torque issues as well as some carb and intake issues but i proved (like you did) too alot of people i can build a nice drag car that was reliable and i wanted too drive it to/from my local drag strip hear in the san francisco bay area calif. Any way andy great job and hope you make more videos of the truck and that impressive mixed up boss engine. mark san francisco calif.

[@jimmymccormick142]

Great video Ford power forever baby l love watching the Ford guys show why we love our Ford power and what it really can do awesome setup keep up the great work you made us Ford guys really proud

[@tracyamcneal9597]

Andy...You and David are putting out the "Real Deal" video stuff. Thanks for sharing your expertise on the small block Blue Oval. Personally, Ford high performance is my favorite. I'm not interested in LS engines. Keep up the awesome work guys. I will continue to follow your progress because its just that GOOD.

[@rockets4kids]

If you're going to replace the entire top end then it doesn't really matter which way you go. So many people go with LS engines simply because the stock top end flows so much better than the stock Ford SB top end.

[@Mike583]

I totally agree, when you see those valve covers, you automatically think it's a Boss 9! The heads are beautiful! Speaking of your shirt,i bought an issue of SS&DI every month for several years. Also Super Ford magazine were my two favorites! Congrats Andy,to make those et's from an NA engine in a 4200# truck is awesome!

[@jims2286]

That engine is music my freind Top Fuel champion Gaines Markley built an SOHC 427 and installed it in Early 1960,s Ford Starliner with Doug Nash 5 speed and ford 9 inch. A few years befor he died

[@garykarenmcgruther6386]

Awesome video, Greg is a outstanding guy. His cylinder heads speak volumes over all others for sure. As for carburators and tuning? May I suggest John Satterfield of Dambest carburators. They are not cheap but, they will out perform anything you can buy plus his advice when needing him for tuning? Unquestionably the best.

[@Robert-mn8gc]

[@therory6888]

Nice build, love the truck. And the heads look great. My Dad had a 69 Ford F-100 with a 360 in it. Bought it brand new when i was a kid. It was a great truck. A lot of good memories. Question though: Why did you go with dual carbs, instead of a single carb? Was it for the potential H.P. gains, the visual appeal of two carbs, or both? Thanks for the video!

[@MsKatjie]

I appreciate that you mention Higgins on the list. They have taken Clevland style heads to new highs, or so I believe. Full marks for sticking with the project. As for the Hammerheads, that used to be Oz slang for a heroin junk! No moral judgment on my behalf, just a sidebar. Cheers.

[@danielwilson6665]

The Higgins Cleveland heads definitely deserve some praise too. In single four barrel trim without any power adders, dyno results have exceeded 1000 horsepower using race fuel. On Aussie pump fuel, the same engine dynoed just below the 1000 horsepower mark. Put that in your LS pipe and smoke it 🤷‍♂️. As more Hammerheads reach the hands of competent Ford builders, expect to see power production numbers that will boggle the mind 🏁

[@MsKatjie]

@@danielwilson6665 Too true. All outa my range. Bought some new iron repo 4Vs. Affordable and still fine for my needs.

I an Australian & Nathan Higgins Heads are simply Brilliant. He also offers a matching intake that he has also developed.

[@davidreed6070]

I didn't realize they were that far rotated. Those heads should support

[@slowg8701]

That's amazing man that thing is a monster!

[@johnelliott7375]

I'm going to say that I am speechless on how it came out to being almost finished.

[@HeadFlowInc]

What’s the CID of mixed up Boss? Looking at a more efficient correlation between CID to Intake runner volume/flow: The heads have way more flow than the CID and Power can use. This mismatch results in a loss in “Average HP/TQ” across the rpm range. An engine making say 750hp with a port flow of 350 cfm would be more ideal. Better velocity/efficiency/higher average. You might try raising the SCR & manipulating the DCR with cam timing, raising the power goal to 800hp, making better use of the cylinder heads.

[@UnityMotorSportsGarage]

It's 429" these heads have great velocity over 300 ft per sec.. to say that 750hp using a 350 cfm head while I can agree but there is A LOT more to that equation in terms of how efficient the port actually is! This engine made 1.39 lbft of Torque per cube on 93 Oct which is pretty healthy considering it was all off the shelf parts.. Thanks for watching Andy

[@HeadFlowInc]

@@UnityMotorSportsGarage Flow bench numbers are not an engine. I never said the heads themselves don’t flow great, I’m saying they DO NOT match the CID/Compression to have an optimized combo. Since you feel you’re above criticism; then good luck with finding the power you actually wanted. JD

[@UnityMotorSportsGarage]

No I think you misunderstood me... I think there are way more variables that come into play vs just using CFM.. trust me I'm not above getting any criticism... Andy

[@JC-gw3yo]

Great stuff Andy....

[@itseithergonnaworkoritaint7852]

I heard that DD Speed Shop has a Holley Sniper dual throttle body setup for sale if you're looking for something that will self tune. LOL

[@UnityMotorSportsGarage]

I'm good... 😆 Poor Dan has been through it with that setup... He will get it figured out Andy

[@youssefkhaled9666]

TJ Strange is probably revving those 400 cubes over 10,000rpm. You either use high rpm or boost to take advantage of that much flow.

[@UnityMotorSportsGarage]

I'm happy for 700 HP @ 6800-7200 for now..lol

Bro your truck is so bad ass. I know it's a sin and breaking one of the commandments to covet your neighbor's ass but brother I love your ass (truck). And I'm right with you on the potential of that engine and those heads. But it sounds looks and acts absolutely awesome. I want to hear this dude with the ridiculous cam and a fuel air delivery system that will make it possible for the little monster hemiboss to breathe for all she's worth! And I dig your channel. You have the best instructor anyone could ever wish for. LUCKY!!!!

[@johnsheetz6639]

I don't know if you ever mentioned it. But I'd love to hear the cam specs you guys came up with. I'm guessing it's going to have around 2:40 2:50 at 50 in a tight lobe separation like around 107 but that's just a guess I'm definitely not an expert.

Another great video andy . You built an awsome motor. Lets be real those are $7000 a pair heads

[@UnityMotorSportsGarage]

Yes they are... I even say that but I see that it is value in potential.. when you buy the kit you get the heads, valves, valve covers, head studs, valley plate, Jesel Valvetrain, plug wires etc.. so you are getting a good bang for the buck especially with the Jesel Valvetrain... Thanks for the kind words and for watching Andy

[@brentonk461ismylostaccount]

Andy, And who? told you to use the 2V cleavland tunnel ram when you found that the intakes you had did'nt fit

[@UnityMotorSportsGarage]

Brenton, I'm using a 4V Weiand Hi-Ram intake. I found that the Boss 302 TR 4V runners were pretty close in size to the ports on these heads. so it was a natural fit. Andy

[@drtb69]

I built a street boss 289 with 351c 2v heads in 1985 BA performance Fort Smith Arkansas ..problem was limited cam selection on those. Are you guys selling these heads yet??? Would like a set for my 408 cube 351w based stroker. Please post contact info if available.
