Not Ranked
I have one and it dynoed 452 HP from the advertised 430 HP. Great motor for the money. Don't rev it past 6200 and it will last a long time. I agree with Terry about the GT40X heads. They are OK, but a lot of HP can be gained by changing to AFR's or other after market heads. Remember the older 392 has cast crank and cast pistons. The new 392 has forged pistons, but still retains the cast crank.
Just my 2 cents
