Looking great. Were just boosted a friend JY 5.3. He has a T6 BW S480, LS1 intake, Stock, LS6 intake, Z06 cam, Chinese head stud, Meth, oem head gaskets and valve springs from the supercharged camaro. At 18 PSI it made 688 WHP through a Th400. The car was shut down at 5500 RPM because he is just learning to tun his Holley system. Should pull to 6500. So a solid 700 whp car on pump gas
