Like the title says I have got a 92 331 stroker with a s-trim supercharger, its been professionally tuned by Panhandle Performance in Panama city fl. My problem is that I have used this car as a daily driver and has been powerfull and dependable yet I have moved to Boise Idaho For the USAF and have been driving around for about four months on the original tune and the car seemed fine and one day I get on it like many other times and after I am done the car starts idleing lower and igniting inside the header internittenly.So I change my fuel pump and wiring again and check compressionon all cylinders and everything checks perfect last night. So ... tonight I take it cruising and running strong but still notthe same and some chicks on the street corner ask me to goose it and of course I did and Ihad the largest backfire two times in a row on both pipes I mean there were huge flames and it was loud as **** and then mydrivers side header gasket blew out and this wasnt the first time of the night that I got on it either it just all of the sudden did this ****, so what I am asking is if you guys can give me some ideas because I am a little to pissed to think right now

Thanks

Might have an injector going bad, and its super rich or lean on that one hole every now and then
I would also check all the rockers and valve springs make sure something in the valve train
isnt broke and stuck open or something.

What do the plugs look like?

well they have some carbon on them they dont look horrible but I was thinking it might have been something with the valves. it smells rich as **** but that doesnt really necessarily mean anything though.

I mean the plugs dont look the greatest but I wouldnt have thought they were that bad you know.

there has got to be somebody out there that knows other things I could try as well
