That sucks Bryan, but better on the dyno than out in the middle of no where. Make some improvements so you'll feel better about having it out. But don't go so far that you can't drive it this summer!

Hate to hear what happened.

Not trying to spend all of your money but....

I had that same exact thought... :D

SO the good news is Don Hardy race engines --- an LS specialist is right there near you. That's who built the motor in the '33 --- and where Brizio gets most of his motors.

My guess on the rich condition is a pin hole or leak in the exhaust UPSTREAM from the O2 sensor - causing it to add fuel to overcome what it sees as a lean condition. Or perhaps that valve never sealed well --- and unburnt fuel is oxygen rich again fooling the sensor.

Hey! You've only gone thru ONE motor --- the Mustang has eaten 4 since I've owned it.... LOL

you'll get it...good to have steve on your side.

It might be a good time to start discussing a different name for the car.
Just sayin

Sucks to hear Bryan.
Hope you get her back to normal soon! Good luck!

Bryan, sorry to hear. It'd be nice if money grew on trees but for most of us that would be a huge set back. Feel for you, hope things work out smooth as possible. Best of luck to you.:bang: Could find the you've got to be sshiiiiitin' me smileee.

Bad Dyno day

Sorry to hear the LS let go
I have done the same in the past
along with many other engine failures

Most NorCal Shelby boys who track their
cars a lot tend to change their springs regularly
Depends on how high you rev it. 7000 plus
all the time does take its toll

You could always go out on the edge and
put a real Pontiac Motor in her:)

I hope you get it running soon

Bob

That sucks, I hope you can save the block and you get it back in soon. Good Luck.

Bryan - I went back and took a look at the top of your pistons and yeah ... that looks to have been running very rich.

The whole thing is really upsetting. And I'm sorry you're having these on going issues.
