I made 454 whp on this bottom end. Went to all motor just selling it to make more room in the garage. It's a 81.5mm with 9.0:1 pistons JE SRP's and Eagle rods with 3/8 ARP bolts. Made 454 whp on pump. capable of more just need a good tuner. You don't need more than that on the street anyways. Don't ask if it's sleeved and why it isn't. You know stock blocks can hold HP with good tuning. Looking for 800 obo.. That's CHEAP..has ACL bearings
