There are handful of good shops in St Pete/Tampa Area.
If St. Pete or Clearwater
LHT does good work and he can also get you an engine. He does very impressive work, very clean. I highly recommend them.
Also Secret Services do awesome work as well you might want to give them a call. I am not sure whether they can get motors or not and they have excellent prices and their work is acceptable, they also have a dyno that can tune it for you for better results.
Also Corey T. does good work as well, I haven't heard of him in a whiel so im not sure if he still does work
There are also some independent guys who are also great.
There ya go hopefully this will be somewhat helpful. Call those shops and see what they can do for you. The best way is to call and get their expertise instead of just going by their websites.
hope to help
