C7&7

Pistons go around 700 or 10+ psi. It all depends on the tune and fueling.

I wonder if the bottom end on the LT1 is more stout than the LS3

Get the Z. It cost me 25k to take a SS Camaro to over 700 wheel. If I had bought a ZL1 it would of been under 9k. The same applies for the vette platform. You will spend more from the jump but it pays for itself right away.

Kinda. The rods and crank and forged, but the pistons suck. The ls3 can take more boost in a SBE scenario.

ZO6LIFE

Exactly , I'm at 800hp now on the SBE, stock intake, and stock heads. I have 12lbs. of boost. But I won't go any further. I'm already pushing it.

This is on my 2013 SS not my Z06

2017 and earlier you more than likely won't find one with any warranty left. The 5 year powertrain warranty will be expired on most of them.

The LT1 could handle the same amount of power of the LS3 as the pistons are the same style construction, the main issue is the tighter ring gap on the LT1 engines. If someone wanted to change out the rings and gap them for boost then the LT1 pistons would do just fine all day long. Bad thing is if you go that far in tearing the engine down you might as well spend the $1200 and put forged pistons/rods with better rings in the engine.

He will still be short about 200 hp.

Forgot to update this post but I got the grand sport and sold it 6 months later for a 2017 z06 w/ the carbon package and Comp seats

You chose wisely

Skid Row Joe

I would get a Z06. (Convertible!)

Factoid

Beautiful and thank you for the follow up and validation that you made the right choice. At least the second time!

I wish all decisions were this easy. GS without a doubt.

for me the wide body is the biggest difference....those 4inches are a HUGE difference in appearance

IMO, the key question before the question is "Who is doing the work?"

If you're capable and have the tools, I'd go GS to learn the platform then add the power once comfortable plus it's always more fun to build and much more gratifying when you win.
If you're farming the work out to a shop, start with the Z06 from the start.

650/650 not enough for you?

dnb007

im making about 700whp now about to do heads and cams to make over 800

Woodson

Is this for drag racing?

Joe’s Z06

Z06 all the way.
