Message: [QUOTE="Hotrodtractor, post: 1076730, member: 25"] They do tend to crack with high combustion temps (high EGTs) - but they can also make good power on stock pistons if you keep those temps in check - for instance I chose to make power with compounds on my LBZ - still rocking stock pistons at 130K miles and compounds of some variety have been on it for 100K miles. Delipped pistons, LB7 pistons, oval bowled pistons (my choice when I do upgrade), all take care of the cracking issue related to temp. [/QUOTE]
