5.3 or 6.0 Iron Block

Starting to think about getting in the market for an iron block to put in my 02 Z28

CURRENT MODS:
Trickflow 225 heads
Custom Grind Cam 228/234/113LSA
Fast 92
Wilson 95mm TB
Nitrous outlet wet plate
150 shot
Under drive pulley
LS6 injectors
Kooks LTH
Kooks HFC
Borla 3" CatBack
3800 stall
Tuned with HP
Stock bottom end
Current tune making 456rwhp/425tq

S60 w/ Detroit Locker and 4.10 gear
Chromoly driveshaft
Weld RT-S wheels

So the question I have is sometime in the future I'm planning on trying to put an iron in so I can run some pressure and get a little more power Some of the questions I have are Should I go with a 5.3 or a 6.0 if I'm planning on running boost in the near future?

Also considering upping my nitrous shot

Will my current mods fit on the iron block? (Heads, intake, cam etc.)

Planning on also putting in a TH400 w/ Trans brake if that changes anything

Also would like some pointers for looking for a motor.

Thanks John

So you want to up your shot and run some boost together?

I went with a 6.0 iron block myself, and my heads, cam and intake transfered right over. It's basically a direct swap for you

I'd go with a 6L block. It's strong and provides more bore for more power...

I'd second Thompson. Their 370 with Diamond Pistons and Scat rods is 3299 shipped.
