Choosing between stroking existing ls2 to a 402/408 or getting a new ls3 525?

What's the word?

 
If I’m building a new car from scratch and I have a budget I’m going with the ls3 package and just leave it be. That being said I have a healthy 427 and really like it. But in the dunes I’m sure I’d be plenty happy with a ls3.

I though you had a 1914 VW??

 
I have a Alper motorsports built stroked ls2. It was a huge difference from the stock ls2 before. Jason changed it to a Holley system and fast intake later. It even made a bigger difference once lance retuned it again with those changes. Use good parts and use a good engine tuner. You will be happy with that motor. 

 
1 vote for LS376 525 - plenty of power with the peace of mind knowing it came from Chevy. Happy with mine

 
I would stroke the LS2.

Buddy did that and wow what a difference.

He did 418 to the ground through a S4.

The Ls2 started out as one of Redline's 550 packages, so going w/ the Ls3 would basically be the same power-wise.

I would think building the Ls2 would be a big difference.

Some will say Ls3 and build it later.

I have 9 yrs w/ 55-65 days a season on the original motor...would it be crazy to expect the same once stroked?

Out of curiosity.....if you already have a healthy 427, what would be your reasoning for not using it?

I’m using my 427. I was saying if I was starting over I would slap an ls3 with a cam in and call it a day. 

 
While not exact what you're looking for...

I have an Alper built 402 LS2 in my TBSS.  My brother has the 525 in his '86 C10.  Both absolutely rip.  Tough to compare with the differences in truck weights, the C10 having the 6l80, and me trying not to yard sale the stock 4L70....

The 402 will be the cheaper route.

Building my existing motor is what i'm leaning towards.

The price w/doing the Ls3 would be pretty much the same....having a friend who is a manager at a dealership get me the longblock and intake, then using everything off the old motor.

Dyno and R&R on both.
