If I keep good fuel in it and keep it under 200 degrees or try to ? The rest is speedmaster rods , scat crank , Herbert hydraulic roller 510 / 280 1.6 rockers , dart shp intake, quick fuel 750 q series carb and a complete m.s.d. ignition . This is going in a 59 international a100 with a 700r4 and 2200 stall , 12 bolt 373 welded up ' not that the last few lines matter on ring gap but I see every one all ways adding all this so well , .

    I plan on using the pistons in a pretty hot 377 street engine. will they be ok to spin 6300-6500 RPM? I have not ever used Keith Black Pistons before and wonder about durability.
