I have a 2002 RCSB Z71 5.3 with 4L60E and 3.73 Limited Slip. I have done quite a bit to the motor and I was wondering what kind of dyno numbers I might get. I have a powerdyne blower with 9 psi (fixing to be 12), 42 lb injectors, a custom dyno tune, ram air hood, 255 LPH Fuel Pump, Corvette Servo and Shift Kit, and I just purchased a 2002 Z06 cam, intake, and heads along with a set of pacesetter longtubes. So I have a FEW questions?

I was checking around and I found out that for a blower motor I need to not go with Z06 heads but with plain 6.0 heads so that I can lower the compression ratio, is this right?

Also I ordered a pulley to take my truck to 12 PSI will it withstand this?

The heads I have did not come with rocker arms can I use the orginal ones off my 5.3?

If I use these heads should I change anything with them like springs, push rods, etc?

What about a 90mm TB upgrade? Or can I use my stock?

Are my 42lb injectors big enough?

What kind of HP do think I can get with this?

I know that this is alot of questions but I hope that yall can help me out. After I do this I am going to have the truck retuned on dyno. Thank yall so much for your time.

 

What head unit do you have with the powerdyne? the powerdynes usually wont put out over 10psi unless it is the new gear driven one. The 42lb injectors should be fine.

 

My head unit is one of the new silent drive units. Its about a year old.
