Switched to a L96 408 stroker

[LsxBuickRegal1982]

My ls3 block need way more machine work then I expected so I opted to go with a 2010 L96 but I'm still going stroker but its a 408

Ls3 0821's will be going to Katech performance for their cnc program and competition valve job

I'm interested, do you have any thoughts regarding the longevity of a 408? I've read that with the longer stroke, the skirt of the piston actually comes out of the bore, causing the piston to rock and leading to accelerated bore wear. The reason I bring this up is that I had once planned to build a 408 for my daily driver. Obviously this wouldn't be an issue for a hobby car or a dedicated performance build.

I've heard the same thing but being my car is a weakened warrior and I have a spare 6.0L iron block I'm not too concerned but I figure since I'm having my machine shop blue print my build and they are offering me a warranty I should be ok.

The problem was with the gen 3 blocks was the cylinder walls don't come down as far as the gen 4 cylinder walls

I'm not a huge fan of strokers in general. As stroke increases so does piston speed. This is compounded by increased RPM in performance builds. I would stay with the stock stroke. 32 cubic inches isn't worth all of the downsides strokers have and it's not like LS3s are hurting for power. you could always get some fancy valve covers that say 408 on them. It's your money, do what you want.

I guess it comes to preference cause it's too many stroker builds and crate engines on the market for strikers to have a reliability issue.

The stroker versus boost argument always results in boost winning both in power production, $/hp, driveability, and longevity. And I am talking a bolt-on centrifugal supercharger, an off the shelf cam kit, cheap headers, and an otherwise SBE junkyard engine.

That 408 is just going to result in disappointment.

I agree with the boost argument but im going to still going to choose nitrous over boost Any day its just my cup of tea and yes it my 408 is carbed😎

I don't believe piston speed is the issue. The increased rod to bore angle of a stroker is what accelerates wear IMHO.

But with the idea of it being a weekend warrior application, I would not be concerned about anything other than not running multiport fuel injection. The nitrous will cause more wear than the any stroker concerns. Nitrous and longevity.......not synonymous lol.


Confucious Nailhead say : the difference between nitrous and a turbo, you'll whip me to the 330' mark, and then I'll drive by like you have an anchor out back 🙂🙂

All kidding aside - to each his own - enjoy.
