Never rebuilt a engine before, doing a ls swap in my 86 chevy long bed. Wanted to go 408 but out of price range. 2002 lq4 6.0 block, bought its from a guy who said it was making top end noise. Thinking I should rebuild with forged pistons with custom cam and either stock 317's or 243's. 430rwhp is my goal. budget build, nitrous added in a few months also. Any ideas where to get a good rebuild kit ? What else should I change to reach my 430 goal? prob go 4l80e tranny also.

 

Check with the sponsors, they should be able to put together a kit for you based on your goals.

I recently picked up a set of Wiseco's for a 6.0L rebuild I'm working on as well. They're a good budget piston for use with the stock rods and have valve reliefs so you don't really have to worry about PTV with a decent sized cam.

Mahle also has a good piston for a modest budget but if you're planning on using nitrous, I'd suggest using a 2618 alloy piston, like the Wisecos. Mahles are usually made from 4032 alloy which tends to be more brittle and less forgiving to the volatility of nitrous.

 

Try Thompson Motorsports. That's who did my build and I'm very happy
