I’m in the process of building a short block for my 2008 Denali, this car will be equipped with a supercharge. What is the best route and what is the best size of motor 402, 416 or 427?
Which piston will hold it self on heat and higher boost? (JE, Wiseco, Diamond)
Is it better to go more bore with short stroke or it doesn’t matter? I’ve seen the ZR1 go with 6.2 motor instead of 7.0Liter.

Sorry for those dump questions but it will help a newbie friend.

Thanks

 

Well bigger is always better but you need to look at bore an stroke when thinking about a power add. 4" stroke to be safe and not smoke with a power add so if you've got an LS2 then your looking at a 403, it you've got an L92 then your looking at a 416. If your starting with an LQ4 then your looking at a 382.
We like to use Wiseco pistons( thicker ring lands)

 

Thanks for the info.
