A friend told me about those heads a while ago, and I've been thinking about those "If I had the money" builds. Very cool, you definitively chose a solid combination for the short block and I know you will bring out the best of those heads flow potential. I can't wait to see what you got planned next!
Thanks man! I'm hoping for 750hp NA on pump gas so we shall see! It's going to be fun in my '71 F100 CASPER!!!
Andy
Looks Great! Cant wait to see those beautiful heads on it.
Thanks, I hoping for big things... Time will tell...lol
Andy
Glad to see you back in here buddy 👍🏼
Yeah it's good to be back...
Sweet can’t wait to here it run
David, I'm with you on that! Thanks for Watching
Andy
I'm amazed you had to have a new engine block machined. I've heard that some new eagle crankshafts have egg shaped journals too! thanks for the video Andy.
Yeah Kurt every aftermarket block I have messed with, Dart, World, you name it all needed to be decked! I was a bit surprised that this starting off as a complete shortblock needed it.. but this build has to be right.. No second chances...lol
Andy
Luv it!!! Can’t wait to hear it run!!!!
Thanks, Im looking forward to it as well! It should be real Healthy...
Andy
Oh Damn, I’m jellos, yep I own a 1969 Boss 429, so life is good, but boy is that a nice setup. That thing is going to rev like crazy. What a dream!
No I'm jealous! Lol.. we are hoping for 750hp NA on pump gas so it should be interesting! Follow along and see how we do!
Andy
man im hangin to hear that gem thanks Andy
Robbie, You and me both brother!
Andy
Soon as you flashed that ring compressor on the screen I thought boy that’s a finger getter lol
Oh yeah.. she's a finger bitter forsure... But we use what tools we have at the time! LOL.... I think it's time to repo my compressor..
Andy
Awsome Video cant wait to see the next one.
Thanks Man, Hopefully that cam will be here SOON!
Andy
@@UnityMotorSportsGarage I truly hope its big and nasty so Casper goes like hell. Keep up the great work Andy. You are definetly my favorite you tuber. I have learned so much watching your channel.
@@josephnubile1970 I really appreciate that!! It's going to be hard to keep a trans alive in CASPER I do believe!! We will worry bout that when the time comes!
Andy
Keep up the great work Unity.
Thanks I will try my best!
Andy
Heck yea glad to see a video from you!
Whats up Sammy! Ive been watching that bad Fox making some progress.. did you figure out what was going on with it?
Andy
@@UnityMotorSportsGarage thanks, the thrust bearing is screwed, I patched it up to race it tomorrow but it’s going to need someone better then me to go threw it
@@Boostismyfriend Man i hate to hear that... Hopefully it will hold and you will make some rounds tomorrow! Get some good vids!
@@UnityMotorSportsGarage I will
Casper is going to be a monster when it's all done.
I sure hope so!!! I'm itching to hit the track again BAD!
Love the channel although, as a West Coast Yankee, I don't always understand Southern colloquialisms. Can't wait to hear this beast run on the dyno. Subscribed.
Thanks, for the kind words... I cant deny being from NC..lol
I'm looking forward to making some noise...
Andy
Those ring compressors are still made over there in the US, I'm in Australia.
I bought one about 4 years ago it's Lisel branded.
I have ruined a set of rings with one when an oil rail got caught. I believe it happend when the end of the rail ring lined up with the overlap on the compressor. $110 later and a new set of Hastings rings and problem was solved and a lesson learnt.
Amen to that... Old Betsy needs to find a trash can! Thanks for Watching
Andy
Awesome Andy your on warp speed. Looks like your going to be bending the dyno needle.
Tim, you know how it is... we spend most of our time collecting the parts we need and then it starts to go pretty good.. I hope the Cam will be here soon! I heard that there is a shortage of cam cores ... I have the Lifters so the Cam and then mocking up to measure pushrods! LOL I cant wait to make some hot water with this thing.
Andy
@@UnityMotorSportsGarage kettle is in to boil, good luck and keep us posted. 🏁🏁🏁👍
Will do Sir!!
What a interesting combo andy,can’t wait to hear it run.i think you shall have no problem hitting you’re mark especially the way you leave no stone unturned. Good luck brotha....
Thank you! The goal of this build was to use off the shelf parts for the build... This is the list of parts and show what it can do.. Down the road it will get alot more in depth..
Andy
As we all Know Casper is not the friendly ghost ! Looks you will need to set me out 2 for sure with that wild build you are doing. I am going to need some of those splitfire pugs for sure.
Well.... im sure that we will find the next weak link Casper's drivetrain... I always do! lol... I just hope that we can have some fun before the fuse burns up! No you need E3 plugs... they are the latest and greatest....
@@UnityMotorSportsGarage Yea i will get some of those and a clear distributor cap.
Well finally something different and that's what I'm lookin for for my fox a different Windsor I'll keep watchin.(just different not the same old thing)
Thanks for coming over and checking it out! Hopefully here in the near future we will have it on the pump and see how she does!
Andy
Ready to see it done. I hate those type ring compressors. It's made me blood before. Once I get past 4 pistons it starts not wanting to compress the rings. So I just buy 2 and throw them away after piston #4.
Oh Betsy has seen better days... I hate using them but you got to do what you have to do...lol
Andy
YES!!!! Let's get 'er running!!
Im so ready! We are hoping to make 750hp NA on pump gas... so we shall see! if you havent seen the cylinder head videos on this engine I suggest checking them out.. I have a unboxing vid and Flow test Vid as well..
Thanks for watching,
Andy
Poor Betsy ! Come on camshaft.. I am looking forward to hearing Mixed Up Boss
Me too! Its going to make some noise forsure...lol
Andy
I was wondering what happened to this build. I've downloaded Parts 1-2&3 and now 4. I'm going to wait until it's running to watch them all, if I can remain patient long enough. Just from reading each video description . . . yeah , I need to not do that . . . but I did and I can hardly wait to hear it run. Cheers from Alaska.
Thanks for being patient! Things are coming together now... More to follow!
Andy
We dominated Division 3 truck pulling with a BBF with GMP 7.100 aluminum BBC connecting rods, Super Cobra Jet cylinder heads and crankshaft , Aris Pistons, mechanical roller cam. We won the championship 3 years in a row. Block was a 68 four bolt main I forgot what the cubic inches was but it was a screamer! Great video.
Heck yeah!! That is awesome... That is a stout combination! Thanks for the kind words!
Andy
Would love a price break down of the build after it’s all said and done!
I will do that... The biggest cost of course is the heads... but the bottom end is something that bad... It could be done alot cheaper on say a stock block based 408.. But I will have a complete breakdown of the parts used and prices when done!
Andy
@@UnityMotorSportsGarage sounds great. I have a stock block 408w with 225 highport trick flow heads in my 70 mustang and was wondering how much it would cost to move up to the next level of power. Thanks!
Right on
Thank you Russell, Follow along... Its going to get good!
Andy
I always say if you ain't bleeding you ain't working on it! lol Doesn't seem like much torque on those rod bolts but I know this is not a diesel.
This motor has my DNA in it forsure! LOL Yeah the 7/16 ARP bolt doesnt take that much torque... compared to a diesel its a different world im sure!
Andy
Great video! Nice lookin' short block assembly!
What kind of paint/coating is on the inside of the block?
New sub, I came over from UTG, great information in them videos.
I usually use some old spark plug boots for the rod bolts during installation.
I did a video on the Glyptal paint I used.. You should check it out! Thanks for watching and please subscribe to follow along!
Andy
@@UnityMotorSportsGarage I will check it out! I did subscribe earlier today or yesterday (don't remember) that's how I seen this not long after you posted it. Well a couple of hours. LOL
@@bigbear5510 I hope you will enjoy the content I have coming!
Andy
Hey Unity MotorSports what's up brother how's it going. How's Casper the F100 doing.
Things are good! It will be much better once I get this new Motor done.. I miss driving Casper bad!
Andy
@@UnityMotorSportsGarage Awesome brother. What's the displacement of that Windsor Block that you're putting the BOSS 429 heads on.
Blood for the horsepower god! 😂
It definitely has some of my DNA in it now! Lol
I've got a ring compressor just like that
If you have one you can understand the pain! lol You have to be super careful when the rings hit the bore so they dont pop out.. and have to start over again... I hate that!
Andy
@@UnityMotorSportsGarage I can't tell you how many times that the rings did pop out. lol good memories, I finally did step up and buy a " modern one". Can't wait to see the finished product.
Yeah I finally thought one day... Yup there has to be a better way... So I bought a "good" one and old Betsy was shoved aside... Until this! Thanks for Watching please Subscribe
Andy
@@UnityMotorSportsGarage I did that a while ago, I'm kinda tired of all Chevy stuff and you break that chain, thanks,,, if you need another ring compressor I've got one. Lol, I bought this one in 1975 so it's like me antique
Just curious. Has that block got the same 3" main bearings as the original Ford block?
No it has Cleveland sized mains... thanks for Watching!
Andy
maybe i missed it but i'm curious...whats the cube size of this motor?
It's going to be 429" 4.130" bore 4" stroke
@@UnityMotorSportsGarage now thats cool..cant wait to hear it run
Thanks! It has been a long time coming... So I'm ready to get Casper back on the road!
Andy
nice job should be a beasr
I hate those ring compressors to man. I have a snap on one that has multiple ring sizes and uses a pair of ratcheting pliers it’s one of my favourite tools. And oh yeah nobody gets to borrow it
Great content man! I got turned on to this channel cuz they say you're the carb master. From the tech I watched, I agree. I've got two questions though. Is it possible to modify the transfer circuits in Edelbrock carbs and Quadrajet carbs similar to the way you put set screw jets in the Holleys? And also, is this engine the replacement for the 393 in Casper?
Yes on the Edelbrocks.. I have never done a Qjet but I would imagine it could be done with some creativity!
MIXED UP BOSS is going to find a home in CASPER and I can't wait!
Thanks for the kind words! Please Subscribe and follow along!
Andy
@@UnityMotorSportsGarage subscribed and rung that bell. I can't wait to see you and Casper ripping up the road again. Have you given any thought to an overdrive transmission in Casper to help with highway mileage? Seems like you could at least match your city mpg, if you could get those rpm down.
@@jr78racer I have thought about a late model 6R80 but I'm going to see how long the C4 holds up first so I can at least do some chassis dyno testing to compare the flywheel vs rear wheel hp on this combo like I did on the 393
Andy
@@UnityMotorSportsGarage can't wait to see what you come up with. Great content dude!
Hey Andy; Great video! I love it! if you dont want to bleed use a pair of gloves; they make tons of good gloves at just about any store now days; And if you are tiered of "old Betsy" (except for MY DEER WIFE) give her a MANS name; I found out through the years many women have given me many of problems, give them a MANS name and it all goes away!
Ray you made my wife and I roll laughing... It's true!!! Thanks for Watching and follow the blood trail... Lol
Andy
Where do you think compression will be after decking block
It came out to 11.1 to 1 I'm running a fairly healthy Solid Roller, so it should run on pump gas.. 750hp NA or bust!
Andy
@@UnityMotorSportsGarage How many cubic inches?
@@lifestream4191 it's the magic 429"
@@UnityMotorSportsGarage 750 is gonna be a strong number... doable, but strong.
Greg has made 640 with a SMALL Hyd Roller cam 10 to 1 compression with a 750dp on Vic jr intake.. he did another on with a small solid roller with the same induction and made 675, this is going to have a 259/263 .674/.705 on a 108 solid roller with a tunnel ram and two 660's and then 2 Dominators... So I'm hopeful!
Andy
The only ring compressor I have ever used is an old school one like yours. I F-ing hate it. next build I'm springing for something a lot better (I know low bar).
I ordered a mme titus aluminium Cleveland short block & they literally forgot to redeck it after sleeving .
10-15 thousands proud, it was the one thing i forgot to check before assembling it 🙄
That thing should make a bowtie eater.
Well... I'm sure going to try! Lol.. but when you've been doing this as long as I have there is always someone faster! Lol Thanks for Watching!
Andy
If you don't draw blood it ain't mechanicing Andy
I hate those ring compressors.
I'm with ya on that Brother! Thanks for Watching! Please Subscribe and follow along on the build!
