Yeah they really make a nice mess all over the track when they go.
I remember watching my dad blow his 427 in his Cobra in 63.
Never did find out what caused it.
I am not to worried about it if it goes but will hate to lose all the money that went into building it.
Oh well here's hoping for the best.

I think gear accordingly , with your rear end gear , you will not need to turn it that hard , pull like a freight train to 5500 will be lots of mph . imho .

I would like to match my times with my 68 Shelby GT500KR conv.
When I quit racing it I was running a 10.20 at 132 MPH.

Much to my surprise it hardly dropped anything on the track.  Chucks of block was the worst of it.  Fluids stayed contained for the most part.  Though once I tried getting the motor out of the car is when it fell to pieces.

When dad's engine blew it oiled down the track real good. Locked up the crank and wouldn't turn.
My dad and me and my 2 sisters pulled the engine and put it in the 56 pickup and hauled it to the Shelby shop in LA.
It only had about 15 passes on it so Shelby gave dad a real good trade in price on a new compleat engine.
I don't what it cost to replace but we ate a lot of mac and cheese for quite some time after that.
We didn't mind because we loved to go to the races and watch dad race win or lose.

That will take all but 700 hp. to get there. That's quite a stout 428.

What goes fast takes your money with it.
So I'm slow & broke, what went wrong?

I guess I should have said that it was supercharged. Sometimes I forget to give all the details.
