[QUOTE="tt335ci03cobra, post: 16370296, member: 68944"] The great thing with the 4.6 that you have is it’s thick, reliable, and stays cooler. Lots of meat between cylinders, and surface for head gaskets to seal up tightly. Yes, running a gt head is great and unshrouds the valve, but the 5.3 actually heavily compromises long term longevity. Big bore strokers live short lives. If I keep the mod architecture after this mill, I plan to build an e85/98 only 11/1 4.3-4.5L sleeved and destroked 9000rpm. I’ll likely have a variant of a voodoo esc build done though with a cpc, 4.9-5.0L displacement restoring some wall thickness with sleeves, etc. [/QUOTE]
