[Cobra75]

Since you're in AZ, I would suggest you find closest engine builder with FE experience. If you have "issues" with the build, you'll have to take or ship the engine back to whoever built it....I know this from experience. And regardless of their reputations, most engine builders have "issues" sooner or later. Two guys in the CACC had Southern build their engines (new 351's),& both had to go back to be "fixed". They do stand behind their work and repaired the motors without charge, but the the Cobra owners were out $$ & time for the shipping.
