Ive logged 2850ms pulsewidth and 1600 F for 1 min intervals for 15,000 miles of stupid hard street miles. stocker pistons just show a little starring I consider them still in great condition. I will machine them and reuse them over a set of maybe crower

Aluminum melts at 1,250 F ish, and aluminum alloys could get a bit more resistant to temperature but Casp's EGT's had be 2,100 F ish

Pat try running Casp on Oxy/acetylene probably last about as long
