Making my Nova into a 2005 GTO Setup Questions

[jumpmanmb87]

Ok so after driving my brothers 2005 GTO I have decided that I want to move away from all the gear and cam duration in my nova to a setup that is identical or better than what a GTO is. That car has very impressive power and also is a very fun car to drive due to the 3.46’s

GTO = LS2, T56, 3.46’s

So the major question is….What do I have to do to my current setup to make the cars identical. Without dropping in a LS2 and a T56

My setup

Engine-

360ci
9.5 to 1
SRP Forged Flat Tops
6” rods
Crane Powermax Roller Cam- Duration Advertised: 292° Intake / 300° Exhaust, Valve Lift w/1.5 Rockers: .539'' Intake / .558'' Exhaust,
GM 202 angle plug heads
RPM Air Gap
650cfm double pumper

Hp- 392hp
TQ- 430LB/FT

Tremec TKO600 2.87 First
12 Bolt 4.10’s Posi

Let me know my options here, any help or ideas would be appreciated

I think swappin them 4:11's with a set of 3:55's would be a great start.
