How much lift is to much in a turbo 5.3
I got a custom grind cam that's 235-235 647-627 on a 114. It's a stock bottom end 5.3 in my mustang. It's better to check ptv clearance but has anybody ever heard of this big of a cam in a stock 5.3 before. It has a 232-242 580-590 on a 116 now. Any ideas.

You can check the piston-to-valve clearance without removing the heads.
The amount of lift on the camshaft has nothing to do with piston-to-valve clearance, which is related to the timing of valve events and is primarily a function of cam duration. As already mentioned, the higher lift will necessitate increased maintenance in terms of verifying valve spring condition from time to time.
