Looks like luck was on your side. Good luck with the repair!

My questions:

1. What happened? Can running too rich cause this (had air in the line one run - bogged for a bit)?

2. What do I do about the #1 cyl now? Just put a new plug in and hope for the best, or are the pieces still in there?

3. How do the rest of my plugs look? I think good.

TIA

Looks like a lot of timing too me. better leak and compression that cylinder, Ill bet you its hurt.

I don't think you detonated too bad. Just just got a real bad lean condition causing it to melt the valve. Detonation tends to pop cast pistons. Step it down to a 100 shot and go a little fatter on the fuel jet. Even with a timing tuner you would have melted that valve. I had my timing way back with my timing tuner and it still melted the valve. I even have a bigger fuel pump in my car and it is running out of fuel on the 150hp jets. I am going with a stand alone system to eliminate that problem. Not everyone has this problem but it was happening to me.

If I just added a stand alone fuel system filled with race gas (pump gas in the tank), how big could I safely spray? 100? 150? Even more?

i have the hsw stand alone and spray a 200/250 shot but i have bigger fuel rails, 42# injectors, timing tuner and the racetronix kit it seems to me that the more often you spray the plugs fatigue and fail exspecialy with the larger shot and im running a 7 heat range plug
