MIXED UP BOSS is Hurt... How bad is the BOSS 429 Small block Ford wounded??

[@davidanderson2393]

I have never been a Ford guy but that is an impressive motor build, always enjoy seeing and hearing it at full song on the track. I was in awe finally seeing it with valve covers off, a real piece of mechanical art.

[@guywerry6614]

Really nice to hear a person taking responsibility for something in this day and age. I don't have a particular brand that I prefer, but that's a COOL motor that you built there and hopefully many more runs and miles to come for it!

[@rodneybyrd9516]

Tough break but at least it's a manageable fix. Whenever you are blazing new trails, making big HP and turning mucho RPM there is a learning curve and wisdom to be gained!!

[@UnityMotorSportsGarage]

Rodney, it could have been WAY worse I definitely dodged a bullet but I'm bound to find out the limit of this thing! Thanks for the support and for watching Andy

[@mikedeal8659]

Andy, I always appreciate your no nonsense approach to KZbin and your devotion to your family. Thanks for sharing and I’m glad it’s not too bad a fix. Regards, Mike

[@UnityMotorSportsGarage]

Thanks Mike! I really appreciate that... Family has to come first! I've been guilty in the past of being gone every weekend racing up and down the east Coast and I learned time is one thing we don't get back! Andy

[@adamrodenberg1557]

Little trick I learned is if you're needing a step to reach the engine in the taller trucks, and you're near an air compressor, just dump the air out of the front tires to lower front of truck a few inches while you're working on it, then just air them back up when you're done.

[@GregsAirplanesandAutomobiles]

Andy must be a seriously strong dude. Lifting that tunnel ram with the carbs FROM THAT ANGLE while leaning over the front of the truck is impressive.

[@UnityMotorSportsGarage]

I'm just crazy I guess! Thanks for the kind words Greg! Andy

[@edsmachine93]

Andy family and friends first. Always time for racing. I'm glad no major failure. The lifter is an easy fix. I hope that you get Casper fixed soon. Have a great day.👍👍

[@UnityMotorSportsGarage]

Thanks Ed! you are right.. I had to choose and this year I decided to be on the beach for their wedding. Next year Casper is heading west Andy

[@318willrun]

"chevies and mopars get sucked in" 😄 Too bad about the "boss", but I have no doubt Casper will be healthy again soon! Yep, youtube is an extension of the hobby for me! All the best to you and Casper!

[@GregsAirplanesandAutomobiles]

Nice work. I learn something from you all the time. It never occurred to me that valve springs should be changed after an over rev incident, but it makes sense.

[@UnityMotorSportsGarage]

Yeah the heat generated by over revving the engine is tremendous! Lucky my seat pressures are intact. Andy

[@newguysgarage6802]

We didn't get to make NNN either 😅 We got stranded 😂 Family always comes first thats not even a topic, always another day for wrenching 😁👍

[@danielwilson6665]

Andy, you’re one of the good ones and it’s so frustrating when bad things happen to good people. As you disassembled the components I was curious about what brand of lifters you were using. But instead of blaming the product, you did the right thing by taking full responsibility for the wounded Hammerhead Boss. It was sounding strong until the converter problem allowed the rpm’s to shoot to the moon. A rev limiter will definitely help the situation. Valve float will surely limit the amount of rpm’s but it’s not a recommended method 🤷‍♂️.

[@IndirectConnection1]

Your family and friends always come first! Btw, even if Casper cant make it to NNN, we still want to see you! Hopefully next year everything goes well.

[@richardtibbetts574]

Arnold Schwarzenegger said NO to his mother’s request that he come back to Austria for his father’s funeral, because he was training for his first Mr. Universe contest. What a robot. I would come to my family and friend’s aid ANYTIME, no matter what is going on. Obviously, Andy is a well rounded person, who consistently attends to his obligations other than his automotive pursuits.

[@autonomous_collective]

May I suggest a Revlimiter until test and tuning is complete? Rev limiter: A rev limiter is a device fitted in modern vehicles that have internal combustion engines. They are intended to protect an engine by restricting its maximum rotational speed, measured in revolutions per minute (RPM).

[@autonomous_collective]

PS, I saw you mentioned it further in the video after I wrote comment. - Regards

[@richardtibbetts574]

I think Andy knows what a rev limiter is. I used to have a 74 Ford F250 4x4 “Highboy” with a 390 in it. I had a Pertronix distributor and ignition system that featured a rev limiter. For a mildly built 390, I decided to be safe and set it at 5,000 rpm. For the most part, except for the 427 side oilers built for stock car or drag racing, the FE series engine family don’t like to rev that high. Rev limiters are the cat’s pajamas though. That coupled with an oil accumulator and low oil pressure switch, go a long way to safeguarding your engine.

[@matthewnosal6893]

Yeah I think Andy by looking at his engine knows what a Rev limiter is… Good grief.

[@larryanderson8049]

Andy you were indeed the luckiest of the unlucky, witch is this case was not too bad. maybe wouldn't hurt to look at rods and rod bolts?

[@jimkillen1065]

A rev limited is a good idea . I remember when i was a kid i bounced the rev limited off 7800 on my 302 Chev in my 68 Camaro when i missed a gear on the 4 speed . I was grateful for the rev limited on the Autometer tach ..i also was running a solid lift roller cam, rocker , joe mar ect . Good catch on finding the broken lifter

[@jamesblair9614]

To your credit, you don’t duck responsibility and try and shift blame on to defective parts or just bad luck. Nice that you caught it and figured out what you were looking at, before the damage was catastrophic.

[@UnityMotorSportsGarage]

Thanks for the kind words James.. I have no problem admitting when I'm in the wrong! It's just one of those things that happens Andy

[@bluecollarcook]

Great inside look at troubleshooting Casper.

[@johnwilburn]

We know you, Andy.... your priorities are right and you put family first like you should. You're a good man. We'll look forward to seeing you soon, friend.

[@UnityMotorSportsGarage]

Thanks Brother! I really missed y'all this year. The clock is already ticking on next year! Talk to you soon Andy

[@RoyMiller-d8y]

You take responsibility well.😮

[@jeffalessi]

I would be scared to death to continue running that brand of roller lifters. A new set of top shelf roller lifters is a lot less money than a complete motor.

[@woodey028]

Hey Andy, I have total respect for you brother. Glad to see it's not catastrophic failure. Keep on trucking buddy.

[@xxkingslayemxxgamer5553]

Yes a rev limiter is a must with that investment 😅 good job Andy

[@UnityMotorSportsGarage]

Yup Rev Limiters were invented for a reason... I proved that! 😆 Andy

[@xr7coug]

Had the same issue with my 408W except the tie bar came off. Roller turned 90 degrees and wiped the cam. Dumped the budget lifters and bought expensive name brand ones. I checked them over really well before installing them.

[@NathansMoparGarage]

You caught it just in time.

[@jeffalessi]

If you don't like Crower take a look at BAM lifters, they are also open on the outboard side eliminating pushrod interference.

[@griffittsgarage]

Hey Andy, don’t forget to leak down all the cylinders. Good luck man. Thanks for sharing. Kevin

What motor did the truck have in it back in the 60s when it was first raced.???

No excuses necessary. Family is always most important. NOW FIX IT AND GO RACING!

[@UnityMotorSportsGarage]

It's time for CASPER to haunt some folks.. Thanks for watching Andy

[@davidresar8256]

From the video it looks like there is a pretty good amount of angularity meaning the push rod doesn't come up exactly straight up from the pushrod cup. Did it contact the lifter and break it? Maybe when it floated a valve??? I'll bet you can find push rods that have a smaller tube diameter close to the lifter for extra clearance. I'm glad it's not all torn up! Good luck!

[@adamprice5276]

Family comes first. The Chanel, and Casper will still be there after your family is taken care of.

[@MarineGrunt]

Thank goodness it showed up in the pan . How about had it just broke and found a little corner to hide in ? As it stands , you got an early warning of real bad things to come . I hate that it broke...but it wasn't a really expensive deal . Best of luck to you and the family .

[@sheridenboord7853]

Good catch Andy. You figured it out. So for that to happen on the over rev to 8600. Does that mean the lifter floated and hit the pushrod to break lifter? I think you better check that valve and stick a camera down the plug hole to see if you touched the piston with the valve.

[@dalegriffin8728]

Good catch

That’s sucks, Andy. But At least the engine did not grenade. Good luck get r done You are right family always first.

Those 3/8” pushrods? If you can fit a bigger pushrod I would. You can never have too much pushrod especially with those super long rocker arms.

[@cabotbroughton7458]

Andy, why would that part of the lifter body break out? And the the other side is also cracked It doesn’t look like it should really see much hoop stress, was there a contact mark on the pushrod? Was the pushrod bent? I know you are blaming yourself and the over rev but I wonder if that lifter was heat treated correctly

[@UnityMotorSportsGarage]

with this setup on the exhaust. the more lift you run the closer the pushrod gets to edge to the lifter. This engine was built to run at 7500 rpm and that is it. once the converter let loose it reved to 8600 floating the valves pushrod made contact and the rest is history. the pushrod is fine. this was just a simple mistake on my part and the Progression Ignition is going back in! hope this helps Andy

[@hoost3056]

Ya think it might be good idea to switch to a flat tappet solid lifter cam? The power penalty shouldn't be that much.

[@UnityMotorSportsGarage]

Nah, I will never go back to flattappet stuff in my own builds.. Andy

[@hoost3056]

@@UnityMotorSportsGarage OK, Ok....I thought it would be cool since DV can make flats beat rollers.

[@DSRE535]

I’m wonder if you’re getting a ton of pushrod flex from such a severe angle with a pretty small pushrod, I don’t know how close the pushrod is to the top of that lifter but I imagine 8600 RPM it looks like a spaghetti noodle lol

[@peterchristlieb]

Those old comp rollers are tough as nails, that’s why they’re so pricey. Too bad you’re dealing with that pushrod angle and small space or a rev kit might help stabilize everything on top. You are damned lucky you caught that brother. We lost the first NHRA Heritage Series championship in 7.0 Eliminator by 1 point due to a tie bar breaking. It turns out that the set of ultra high quality rollers (14 of them are still in service) never had the nuts steaked and loctited from the manufacturer causing a recall… anyone can make a mistake and I stand behind those products even now but it was a hard pill to swallow. You’ll be fooled thinking you broke a rocker since the motor will run but this particular motor it went all bad and debris went down the front drain backs and broke the bottom timing gear (SBC with BBC Snout, they have a thin gear and key and I don’t recommend them in blown applications anymore). We raced awful hard that year and had a lot of learning experiences (My rookie year as a crew chief) I wouldn’t trade any of it for 1,000,000.00 bucks. Much love and respect man, I hope you can prevent that from happening again.
