Roush wouldn't include a 3 year / 36,000 mi warranty on an otherwise bone stock 5.0l engine if it was certain to grenade the engine now would they? It certainly will make a 2,400 lb Backdraft scoot. For horsing around on the street I don't think completely rebuilding the engine is economically practical. Put it under the stress of drag racing and a lot of things will need upgrading.

You are attempting to find reasons to believe you do not need to worry.
Another friend before switching to a bigger Whipple used a TVS on his Cobra. He ran 8.5x's et's with a 2.3L TVS at about the same weight as Harold.
I think you should just bolt the blower on. You will embark on a journey of discovery and importantly you won't need to ask for any assistance because your engine will speak to you in unmistakeable terms. Best of all you will eventually graduate from the school even if you have to repeat a course or two a few times.
