Now that you have read all that, let me say this car has been a blast and a lot of hard work. I've drove it many a days.
What’s it need:
The intake valve on #8 cylinder has seized, hit the piston top, cracked the piston and bent the valve.
So now it needs a motor now.
This motor can be rebuilt. It will cost anywhere from $1000 to $4000. It all depends on how far do you want do go.
I’m just sick to my stomach, I just finished installing the Fitech 400hp system, put about 100 miles on it and now this.
I’ve spend $1000s on this thing over the last 2 (6) years and now it’s come to this.
Time to let someone else take over.
I’m done.
