Dreadnought flowbench, for flows beyond 400 cfm. I had a mentor like Mr Vizard in earlier days. Having a mentor with a penetrating mind like that is life-changing. Respect.

[@UnityMotorSportsGarage]

I fully agree...When I first met him.. I quickly realized how much I didn't know! I've been fortunate enough through the years to do some amazing work with David! Andy

Those heads are truly impressive. It's about time someone came out with something like that for the SBF. It's also amazing how extravagance such as that are pretty much a bolt on unit without requiring tons of custom equipment to go with them.

Perfection takes time. Don’t beat yourself up, I have been working on a 1956 F100 now for 8 years but plan to finish it up by winter. There again perfection takes time. What is the compression you plan to have? The short block looks like a dish piston and the heads look like large chamber. Talk DV into trading up to a good used bridgeport.

[@UnityMotorSportsGarage]

Mark, the compression is going to be 11.1 to 1, the chamber is pretty shallow and is only 63cc.. on the bridgeport he has some big plans once the other room is complete.. Andy

[@jasonwalls1277]

I was gonna ask you about what's taking so long to get this project moving. I know it's not a cheap but definitely wanna see this bad boy come to life.

[@UnityMotorSportsGarage]

Jason, the crazy part is I had 95% of the parts last year.. it been a matter of time! Between work and family stuff that is why it has taken this long.. but we are on track now to make some hot water with this here in the near future! Thanks for Watching and understanding! Andy

[@johnsheetz6639]

I saw some dyno vids from hammerhead. Wow! Single four too. Be careful!!

[@UnityMotorSportsGarage]

John, the goal for MIXED UP BOSS is to make 750hp on Pump gas... I think with the solid roller that I'm running with the tunnel ram it should get me there... Greg's street builds all make over 600hp with small Hyd. Roller cams with a 750cfm Holley... So it's going to be interesting! Stay Tuned! Thanks for Watching Andy

[@rotaxtwin]

When you have to move up from the Superflow you know you're going down the right road. Holy!

[@UnityMotorSportsGarage]

DV's Superflow is old! His is a SF-300... I couldn't begin to tell you how many heads we have flowed over the years on that bench... They make benches now that FAR exceed the old 300... But it's still my favorite since I cut my teeth on that bench Andy

[@rotaxtwin]

@@UnityMotorSportsGarage It sure goes to show how far things have developed. We're no longer trying to milk the most out of a set of 50-yr old production cast iron heads.

[@shanerorko8076]

I heard on a porting video that hemi heads aren't the best for N/A because the line of sight during overlap is too good and you get too much intake charge hitting the exhaust on overlap. He said hemi heads are better suited to boost for this reason. Mind you this guy ports inline heads to 400cfm so he must know a thing or two.

Awsome video, cant wait for the next video. By the way what compression be?

[@UnityMotorSportsGarage]

Thanks Joseph, The compression ratio measured out at 11.1 to 1 Andy

[@cjbert6790]

You guys have verified why the boss 429 was a great nascar engine. A great head coupled to a big bore, short stroke big block that was happy at 7000 rpm in 500 mile races.

[@UnityMotorSportsGarage]

CJ, when you think about it.. it does make sense.. with the head design it was meant to run wide open on superspeedways and operate in a narrow rpm range... The team's of the day figured out to make it work on shorter tracks they filled in the bottom portion of the port to make it D shaped... This reduced the port volume and increased velocity and port energy.. which made much more midrange torque... That helped the car come off of the corners.. Andy

[@cjbert6790]

Unity MotorSports Garage Dude, it was engineered that way by Detroit engineers. Ford hired some smart guys to do their new line of canted valve engines!

[@cjbert6790]

Hi Andy I like what you and DV are doing with both your channels. I miss seeing Casper in action. I am building a big bore dart block 347. I am having trouble with solid roller lifter to bore clearance. It seems the lifter bores are a little on the large size and most if not all lifters made are on the small side. Could you and possibly DV do a video on this subject? It might fit in nicely with your build also. Regards Andrew

That would be a great topic! I will talk to DV about it.. Andy

I tip my hat for drilling those heads… especially right thru the cool hammerhead! I know it’s for a good cause but I would have been sweating bullets nervous on that one. I’m so excited to see this project get closer and closer to completion. Do you plan on a dyno session before it goes in Casper or just a chassis dyno after? Thanks for sharing the build and teaching us all something along the way!

[@UnityMotorSportsGarage]

Brandon...I was extremely nervous! It turned out pretty good though... On the dyno, We are going to run it on the Engine Dyno before it goes into Casper.. Then im going to do a Chassis Dyno afterwards to show the difference between the two.. Thanks for Watching! Andy

[@Lagrange1186]

@@UnityMotorSportsGarage now that’s awesome! Not a lot of folks show you how much loss you get thru the drive terrain. Would also be cool to compare how much loss the Lenco has once you swap that in too.

Yeah I think it will be good for people to see how much a 4500 stall converter eats up in terms of power... I did the same test on the 393w and I was Shocked! Andy

[@bcbloc02]

@@UnityMotorSportsGarage I am going to guess 15% loss from engine to the ground. Of course considerably more below the stall speed with a non lock up converter but unless it is a loading type chasis dyno like a mustang you could not measure that.

His SuperFlow is a OLD SF300! We have updated it over the years... it still works great But it has its limits! Andy

[@inspectorbusiness4892]

I see these have made almost 1000hp on their channel. It took a lot of rpm in their case. And a 1700 rpm spread from max points of hp/torque. With your tunnel rams, I bet those numbers can me made much more desirable. I bet you can break 1000hp and have more torque at a 5000rpm then in thier combo.

[@cjbert6790]

From my experience, hemi style heads always make max power at high rpm!

[@inspectorbusiness4892]

@@cjbert6790 interesting story. The first 426 hemi where used in vehicles to pull trailers. In the early 60s a well know drag racer who used w series Chevy in his sling shots, pulled his car with a hemi. After the first trip to the drags he realized how much power the hemi made and took it out the following week for use in the race car. The introduction of the hemi into the NHRA was born. Dan Knapp eventually joined the ramchargers group. They actually made more torque as a 426 then the 454 Chevy and Ford big blocks of the time. The big block Chrysler bottom end is still the leader in low rpm torque per cubic inch. Even more then the 455 buick.

[@cjbert6790]

I thought it was funny when dv said they weren’t quite race heads. They sure look race to me!

Yeah, I know.. even if you ask Greg Brown he will tell you that when he designed the heads it was done as a street head! To give people who want the look of a BOSS 429 in a small block package.. when he first got them on the bench he quickly realized just what he had! These heads out of the box will support 800hp!
