Hey guy I need some help in here with building my motor. I have never built a GN motor only v8s. I have found some upgrades when I pulled the motor apart. It has a Comp cam, looked to be ported stock heads. Done by parrot? I found out the cam is 10 years old and same with springs.It has 60lb injectors. I have a Percision intercooler with a precision turbo. The TT chip said on the back 25+psi. Any recommendations on a new cam, springs, heads or possibly a bottom end? The car is a street car just looking to make it fun and reliable. I have never had this motor running. But it was running before I bought it with all these parts.
