You were in the right place in the other thread where you asked the same question. My answer: Know the reputation of who you're buying from, if the deal sounds too cheap it probably is, and check the warranty. If the warranty states having to ship the engine somewhere for work, if needed, you will probably be paying shipping both ways. I personally went with a GM performance engine. If I need warranty work I can take it to the nearest GM dealer for work. 383 stokers are great, though. Good luck in your decision.
