Need help predicting this cam
Need help predicting this cam What should I expect from this setup with the engine specs below? Power estimates? Power band? Does anybody have anything close to this setup? How does the overlap in the cam look? Would your opinions change if up to a 200 nitrous hit were involved?

Its tough to really ballpark it on a 402. its kind of a smallish cam, however those heads seem like they flow absurdly well, L92's? If so theres too little knowledge about them yet, but valve shrouding seems to be an issue.
