So you think you had a bad day? Must see!

Well, the Boss project was ready to go. All we had to do was dyno the engine drop it in and we're rolling. As we were heading to the dyno we noticed the new SFI flywheel was left at the shop 90 miles away. We had a stock 460 flywheel available so it was either use that or don't dyno and just put engine in.

We made 5 runs with a high of 755 horse and over 700 torque. The headers we were using were a test pair from Kaase that he said showed a 60 horse or more decrease from the actual headers we are going to use. This means we have an 800+ horse street engine.

We decided to make one last run after jetting the carb to balance the power.

Here you go: This is a link to the video of the run.

The flywheel came apart, blew through the block slicing the starter in half. It then went through the wall into the next room hitting a metal cabinet.

Man,that is bad luck and good luck wrapped in one.Bad that it came apart good no one got hurt.Good example why to use the sfi stuff. Hope kaase didn't want the headers back.Were you using arp flywheel bolts or stock ones?Looks like the bolts give up first.

Glass half full

I've always tried to look at things glass half full.

Positives

1. With the smaller tube shorter headers we still got 754.5 HP @ 6400 and there was more to get with tuning

2. Also got 712.4 lb ft torque @ 4900 with 598 lb ft @ 3500 rpm. That's real power from a 10.4:1 compression with a fairly mild roller cam. If Kaase is right (usually is) and these headers knock off 50 or more horse we have a streetable 800 horse engine.

3.No one got hurt

4.460 blocks are still pretty easy to find

5. We got a carb tuned in pretty well for the next engine

6. I didn't get a single rock chip in the mustang from driving this summer.

7. Will be easier to mail Jon Kaase a check than returning the header

8. Did not hurt the Boss heads!!!
Negatives

1. Destroyed block and delayed car again

2. I have to call Jon on Monday and let him know about his header (unless he checks the forum)


Still guys..... 800 horse street engines this easy! How great is that!

I totally agree that the horse power #'s are great and congrats on that. I think you could repair the block tho.Weld the bolt ears up and redrill and tap them.Or did it do other damage we can't see?Bolts only hold it together dowels should hold the twisting.

Terrible

I can't imagine what it felt like when that let go.
Very sorry to see that happen so close to the finish line.

My god am I sorry to see that
Impressive numbers though.

Hopefully this is a low cost/stress rebuild and your back at the dyno soon.

Block

We thought about rewelding the mounting points. There is a crack up near the manifold also and a crack near one of the dowels. With this much horsepower it would probably be better to find a new block. It's kind of like blowing up a grenade at the back of the engine. How much stress is there we don't see?

Wow... that makes me want to shed a tear for you. That just sucks.

Glad no one was hurt. My father knew a guy in the late '50's who was reving an engine in a parking lot showing off and the stock flywheel came apart and took off half of the guys right foot. Glad no one was hurt. He never let us use stock flywheels in our '69 Mustangs.

Sorry to see that happen. Glad everyones OK tho.

That thing sure was sounding good right before it went south.

Will the crank be OK after the flywheel let go (balance issue)?

I'm sure Jon's understanding!! He has prolly had a couple of blow-ups on the dyno too!!

Good luck!!

Bill

Recently at Twin city dragway in monroe la. some guys i know that run a 68 fast back round tube car has an all aluminum 540bbf in it,they had been having problems with a powerglide holding up in the car so they switched to a 4 speed lenco,titanium bell,alum.flywheel and so on.They driver was coming out of his burnout and the flywheel let go,went threw the bell and out the right side of the car hit a woman standing between the track and the tower.She had her hand in her pocket with a cell phone in it.A part of the flywheel went threw her hand,cell phone and into her leg.It went deep enough that they had to remove it from the back side of her body.When they got it out they said it was so big it had seven teeth on it.She lost her ring finger and has had to have several surguries but is doing fine now.They sent all the remaining parts to sfi foundation to see what happened.

Wow !! I had the speakers way up, and that made me jump. I hope a block is all you need.

Where's my beer and that half inch wrench?

I had my speakers up too loud also, WOW! Sorry to see that happen, but glad everyone is alright. Hopefully you can put it back together with just a block. Good luck.
