I have a 12 sive engine and keeps on stalling after half a tank while appling full throttle.what is happening.what could it be??[&o]

Sounds like a half-tank leaning issue. I believe it is something to do with insufficient back pressure in the tank, and this causes less fuel to be forced into the engine - effectively leaning it out. This is why it stalls at full throttle...

Re-tuning (richen up slightly) when the tank is half full (or half empty ) should prevent the stalling, but would be a pain in the butt doing every 1/2 tank. A different tank should fix the problem if you can find one which fits your car (i believe this was a problem with one of the first Savages, and the solution was to swap the tank).
