Just my opinion, but I would stay away from Roush. They seem to have had a our of the norm number of problems with their engines. You are also paying a premium for the name, and you can get just as good, or not better from other builders.

Then I have one question for you.

Do you want a Big Block or Small Block? Make that decision first and go from there. Either one can be built to suit your needs.

Forgot to mention you have made a fine choice in manufactures. Not that it's better or worse than some others, but it's in the top 3 of quality in my opinion.
