Was just nosy where exactly that was at to get to that power output. But I’m a big fan of the 4” stroke on the LS platform. It does the things...It was about .600" lift and 230s duration at .050" if I recall correctly (something around 231/239). The stroke was 4" and the compression was 11:1. I ported the heads myself, mild port job, nothing extreme. I wish I could remember the LSA but I have too many cams in my head now, if I picked it I probably would of picked 112 for that one, but I didn't pick it. If you are looking for a cam I would be happy to help you pick it out and order it for you.
We actually did a lot of testing on that engine, including a small shot of nitrous, and with a carb.
The carb picked up 15 HP and 19 lb-ft of torque on just the volcano inserts, and the small 100 shot of nitrous picked up 152 HP and 223 lb-ft of torque! The same long block was used in every test. Only swapping intakes, induction style, or adding N20.

Pretty sure I’ll stick with the cam I have in my engine. I’d have to compromise too much of one end or the other to gain anything
May be a while before its dyno ready as the block isn't machined yet. I'll post some numbers maybe in the fall, depends on the customer's schedule.
