400 HP possible?

Stock 225 rods are 6.7 inches long. The K1 rods are 7 inches long. That's a difference of over a quarter of an inch which will put the top if the piston above the deck surface. Have to agree with you on Wiseco pistons though. Good pistons and great service. Try their 2.2 Turbo pistons if you want to use the K1 rods. You'll have to do a little more boring than you planned on but the block will take it.
