Engine 1990 Opinions on camshaft

That cam has substantial duration. So to get the most of it you'de need to rev it pretty high. Is your bottom end up to the task? I'd want at least a quality rebuilt bottom end with full balancing. If you have a higher mileage stock bottom end, I'd say that cam is flirting with disaster.
 
So you have TFS R intake? I suppose that means fuel injected right? Do you have a tune on the ECU? If not it might limit your top end rpm to something below 6500. Mine stock set rev limit is at 6200.
