Re: Good camshaft for 5.0 au series 1.
Yep with 2031 on std springs and retainers.The springs are NOT up to the agressive lift / ramps and I'v seen the valve stems stretched and not far from breaking due to valve float etc...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
