What痴 going on people. Got a LQ 4 that I知 born out to a 6.2 I知 looking for pistons any ideas tmanufactures suggestions? Looking to get high 500s HP

 

Fixed it for ya....

 

There are literally hundreds of combinations that will work, you're going to have to get more specific.

 

Probably worth having the LQ4 block sonic checked before deciding. Have heard of a few being able to go ~4.1 to 4.125 bore.

Wiseco and Mahle are my pet favorite NA piston manufacturers. There are lots of outstanding products for various manufacturers.

What's the intended use for the engine?
NA? NOS? Forced Induction? Drag racing? Driver? Road Course?

For cars or trucks that drivers, no forced induction or small amounts of NOS, Mahle has excellent 4032 material pistons. They fit tight and are very quiet. My 72 vette has these type in its Dart 400.

The 2618 material pistons for more high performance applications. Tougher in performance applications but has less long term durability in a driver also more prone to be nosier in some cases. Have Wiseco 2618's in the LS strokers.

 

Here is my review of my Mahle OEM replacement pistons I used in my L96.

WS6Store has some great pistons, engine rebuild kits and cam packages.

They seem to have the best prices and great customer service.
