I now know that "Thermocycled"
is mopars marketing term for reman
I have no complaints with the product I received. It runs great and has every bit of 390 hp
I do question how the new improved version with the race block, aluminum heads, 10:1 compression ratio, forged everything, and the tuning and dyno testing can only make 15hp more
for $10,000 I would think I could take my other stock r/t block and build a 500+ horse small block
