There have been several similar crossflow heads made for the 300 Ford six, even some more modern versions using LS heads. I never understood why the aftermarket didn't come around to support the 240/300s, as they can be built to outperform a lot of V8s. A D1ZE part number is a '71 4v Cleveland/CJ/351Boss head, as they only made Boss 302 in '69 and '70. (C9Z and D0Z) p.s. Check out the Frenchtown Flyer, he's been around for decades, drag racing 300s.
Thank you Mrs. DragBoss, keeping me inspired, and the girls interested. I need the help in the DragBoss Garage, Hey you better answer these comments, lots of good stuff from your subscribers, thanks guys!!!
I just called my old boss, he said the cylinder head he had was built by Bruce Sizemore, he was an engineer for Ford back in the 60's and 70's? It was furnaced brazed together.
How about having someone with a 3D scanner scan the head and share it with someone that could cast one? I'm sure some people would be interested in one??
I would be more interested in a TFS 11R 205 CNC head for the 300, while we're asking. lol A 300 oem steel crank from a medium truck, stock rods(arp fasteners) and forged light pistons would support 650+ hp with a head like that on it, and be very streetable.
@AmericanThunder I have been trying to find the forged crankshafts. They exist but no one is selling them. I called Scat and they want $7500 each if they wanted to make them......
Wow, I saw one of them when I worked at Danbury competition engines back in the early 80's, It belonged to Drake Viscome and was a very impressive piece!!!
Adam, I know Drake and Vindicator Racing. I bought a pile of used parts, including my Endyn high port iron heads from him. I even got a good deal. Imagine that. 🥴
@@danielwilson6665 Too funny, I owned a 1970 boss 302, that at one time belonged to his son, sold it years ago to buy kitchen cabinets in my first house, one of the biggest regrets of my life!
Nice job, Mrs. and Mr. Dragboss. The informal conversation works well. It's like your neighbors stopped by and your getting them up to date. Thank you for inviting us in. I must say, I'm missing the Bossets though. The six-cylinder Cleveland Head is interesting. If I'm not mistaken it's a mix of D0 and D1 Boss 302 Heads as the casting numbers and filled water ports are apparent. Reminds me of Sizemore. Also nice to see Kitty coming along. Andrea, please relay to Mr. Dragboss look forward to his video with Bob Beach. Plenty of Automotive History and interest there, no matter your brand affiliation (and cool Tractors too!)
Thanks Bill, it is really fun, as I am just trying keep moving forward on the Cat, and doing my thing and Mrs DragBoss rolls in. She wants me to get the Cougar done soon, so I can get back on the Mustang. Try to keep all projects going steady. Gearbanger offered me. 240 six, so thinking seriously of getting that and maybe talk to Ken Ellison who has built one and do a project together. Just have enough on one plate, but always hungry. Yes those Bossettes are the bomb. Thank you my friend. Yes have some more Bob videos working on.
You two work well together and the videos are full of information many of us can use. Much of this knowledge is applicable to other engines and cars other than Ford. Great live podcasts with people at the cutting edge of modern technology. Bless your family. 😀
@@DragBoss351Cleveland …. Tim did you say Andrea was filming ??? Who develops your film or do you have a home photo lab ? No matter how fast video technology advances the nomenclature remains the same LOL. That high port straight 6 is a beautiful thing. The D1ZE-A heads were typically used for Boss 302 service replacements. I appreciate the awesome video guys.
Certainly looks like they were originally boss heads. Drilled for Windsor intake manifolds at the ends, and the water jacket holes have been welded. Just subscribed. Regards Greg
Hey Ken, I’m using 3M weatherstrip adhesive , I use it on all gaskets, but just a little. on the header gaskets. I liberally coated, never have to touch it again.
That’s sweet!! Do I see a tractor in your future to utilize that 6cyl boss 302 head to put that Chevy tractor to shame??🤣😂😂🤣 Would look cool though!! Have a great day!
Mark, I don't think they had the option back in the day when these heads were raced. Today, no one would even think about building a head like this out of iron.
Yes, he answered your comment correctly in regards to they didn’t have aluminum heads like that back then. But I answered you, so check it out. Thank you.
Now,since you have the Cleveland 6 cylinder head, are you going to build a 300 6 cylinder engine for your girls to race? It should fit in a 67-73 Mustang.
Be still my heart. Two things I love; Cleveland heads and custom cross flow heads for straight 6's that didn't come with them. 😍
Good evening Mrs Drag Boss

Smarter Man than I am I would have picked it up and put it on the table. LOL
I am too old for that John, already have a lame back if you remember
Thankyou for the update, Mrs. DragBoss. A 6 banger Cleveland!
Thank you Mrs. DragBoss, keeping me inspired, and the girls interested. I need the help in the DragBoss Garage, Hey you better answer these comments, lots of good stuff from your subscribers, thanks guys!!!
Back in the 70's a few guys from Michigan ran a Pinto with that Boss head on top of a 300-6. It made some record passes.
be fun to try a build Dave
The D1 head is the 1971 head. The heads used had to be Boss 351 heads because they only made 1 1971 boss 302 and my guess is it had 1970 heads on it?
Yes, any Boss 302, regardless if it was titled for 1971 for whatever reason, would still have C9 or D0 numbers.
#24& and Holder of Subscription holder's #68 I should be able to remember that one. Great day to be there.
Hell yeah! hold on to what you got
Ya new to me. Look like it would make more horseys
I bet it will....Stay tuned
Wow never seen one of those! Now you need a 6 to build!
I have only seen in pics, and now reality is here Mike

Not sure on that, Bruce DragBoss' buddy had some made, his name is Sizemore i think

@@terrycarter8929 The good news is, the regular old cast iron 300 cranks are very tough, too. 7 main bearings helps. lol
That Ellison's Machine Shop guy rebuilt a 300 with one, it had throttle body injection and all go check it out
Awesome 👍…. Love that 6 cylinder Cleveland head Great video
thank my friend, now another build?

@@adambergendorff2702 … I feel your pain in regards to the Boss 302 deal. Wow man now that qualifies as a total bummer 🤷♂️
Many years have passed since I last spoke with Drake. Do you know if he’s still amongst the living ?
Work smarter not harder, save the back. Also, what’s that I see, a surgeon with a dull knife? Lol, keep up the great work. Thank you Dragboss Team!
lol, yes don't tell anybody, love the little switchblades....Your welcome from DragBoss

Thanks! I tried to get bossettes for this video but they were busy eating snacks. Lol. I am definitely learning along the way. Thanks for watching.

Your right on mate, thanks, she better get on her, there are lots of comments for her.Thanks Greg
Boss 302 would be C9 or Do that is a 351 Cleveland head .
it must be a boss 302 casing it has the water ports welded up.
Actually, I have seen one. Louisville native Joe Williamson did the same thing to power his Altered class roadster back in the late 1970s.
I have seen something close to it. If it is what I think it is.
It sure is..
What brand of glue are you using on the header gaskets?
Hey Ken, I’m using 3M weatherstrip adhesive , I use it on all gaskets, but just a little. on the header gaskets. I liberally coated, never have to touch it again.
@@DragBoss351Cleveland Thx Tim
Move the chain
That’s sweet!!
Do I see a tractor in your future to utilize that 6cyl boss 302 head to put that Chevy tractor to shame??🤣😂😂🤣
Would look cool though!! Have a great day!
I would rather have a car with a 6 cylinder Cleveland head, hmmmmRick
I’ll build a V 12
Why not use aluminum heads ?
Mark, I don't think they had the option back in the day when these heads were raced. Today, no one would even think about building a head like this out of iron.
@rotorr22 yes back then I realize but I'm. Talking now ..more options..too bad someone couldn't cast some !
@@MarkA6070 they did make an aluminum head like this in the Ford motor sport catalog, made by Alan Johnson back in the day I believe.
Yes, he answered your comment correctly in regards to they didn’t have aluminum heads like that back then. But I answered you, so check it out. Thank you.
Now,since you have the Cleveland 6 cylinder head, are you going to build a 300 6 cylinder engine for your girls to race? It should fit in a 67-73 Mustang.
Yes the sub below, GearBanger 57, offered me a 240 6, so I think I will take him up onit.
Hahahaha you got yourself a real cougar lol. Her channel finna blow up bigger than yours lol. Smart move gigga.
Email sent on that engine.
Thanks banger I think we should do this build with 6 cylinder Cleveland headed 240-300, once I get a few projects done,
Is it a 351 boss or a 302 boss ?
It is a 351 Cleveland, that now displaces 354ci, Not a Boss, but meaner than a Boss
How much power will the BA head add ????
