I have 2 Shelby blocks and feel that they are very good in terms of finish and can stand up to big power. They are very good quality and I am not budget sensitive. I do know that whatever Robert Pond makes is good quality and designed for severe duty. I did buy some parts from him for my 427 SOHC and they are works of art. I do not think that you can go wrong with either and if the motor is built well, you should not have any problems. There are plenty of engine builders who visit this forum that have worked with both.
