I think your remarks are unfounded and totally unsubstantiated, including
the one "Make sure all the mistakes are in your favor". Joe Mondello is one
of the best when it comes to building engines, and especially olds 455's.
No one makes one that puts out more Horse power.
If you had taken the time to get a copy of his technical reference manuals
you would get all of the answers without jumping to conclusions or starting
more myths. In camshafts you get what you pay for, and I sure would not go
locally to buy one unless I knew an awful lot about the person doing it.
Want to start a real controversey, take your olds heads to your local
machine shop and ask them to recondition them. After they say they can,
have them explain how they will do it. Than ask them if they can put in
hardened valve seats and when they say sure, ask them how thick they are.
Tell me what they say for the valve seats.
The problem is not with Mondello it is how you ask the questions. They are
not mind readers.
