bryan, this is the wrong place for this question. we are v8 folks, not v6 folks. compare the casting numbers on the "new" parts to the same parts you currently have. at least then you will know if they are the same or not. but i bet you would not see much of an improvement with this block and heads. after all, pretty much all of the extra horsepower in the supercoupe came from the supercharger.
To be honest, the V6 section on StangNet is worthless for any sort of engine questions. All that group is interested in is wheels and exhaust, forget about actual technical questions. I hung out in the 94-95 Tech section before I got my first V8, learning as much as I could.
Bryan20, it sounds like your gains will be really small, if any at all with the Thunderbird parts. And with the new heads, you'll probably have to get a tune for the computer to run right. That's a lot of money for a small gain. You'd be better off either dropping in a V8 or selling your car and buying a used GT or Cobra.
