He's not 100% sure what his compression ratio is yet. Sounds like he has access to a cam his dad has that may be in the running also. He has options.

This ^^ I am not an expert, but I am sure the compression is going to come in right around 9.5-9.8. but if my dads cam is still well suited and is accessible right now, why not go with that and not have to wait.
