Message: [QUOTE="CTFFEMT, post: 1388354, member: 9572"] Looking for some input and help with my build regarding piston options and machine work. Truck is a SRW DD ZF6, somedays pull a smaller tractor, nothing too heavy. Once a month I pull a 20' enclosed trailer with toys for track days and winter time head north with sleds in tow, again nothing super heavy. setup is 238/100s, S369, headers, carrillo rods, methanol injection, GH stage 1 cam, head and main studs + girdle, and all other supporting mods / parts. If you guys need a whole rundown i'll gladly list. Motor is down to just the block and is at the machine shop. I'm waiting to hear what size pistons i'll need to order. Question with pistons is... will it be worth it to do the ceramic coating and de-lipping? I can't find much on these options in relation to the 7.3 specifically. Just wondering if it is worth the extra change. Obviously I am deep into $$ this go around so if it is worth it I will do it. Just would like to hear some input. Was considering Fire ringing the heads / block for insurance but my machinist is steering me away from it. Seems to think it is a bit too overkill for what I do with it as well as power level I am at. I tend to agree with him. So then he discussed o-ringing the heads only. Showed me a couple motors / heads with them and I have heard it discussed with the 6.0's but haven't heard anything about the 7.3. I know the metal ring on the head gasket around each cylinder is not perfectly circular. I discussed this with my machinist and he is going to look further into it and call the company he gets the plates from and see if they offer one for the 7.3. If it is an option...is it even worth it? max PSI out of the 369 should be around 50psi correct? OEM head gaskets + studs should hold this correct? Thanks guys [/QUOTE]
