The LS7 block will handle it. The 6.2 liter has a shorter stroke and you can fit the oil squirters easier. The non-siamesed bores are better for cooling. My engine would never live thru a GM's durability tests and meet all the validation requirements. But I'm not expecting this engine to meet emissions and 100,000 mile powertrain warranty. The bigger bore and stroke make it harder to balance all the issues listed before. We are also pushing the blower harder than what it was validated to. But I guarantee this will last much longer than most "aftermarket" stuff.
I want to make big power for a hot rod. I'm in uncharted waters for a road race engine. If I can keep it cooled it will work. Jackass had no issues with cooling so I'm following that combo and added about 30% more cooling capacity.
