I need help

A little late on replying here, but I’m not sure why this is posted in the LS Performance section.
Depending on what you mean by rebuilt, I’ve done everything down to the block (Removed heads, timing chains, camshaft and valve replacement [done by shop]) etc. but no piston or crank work

Several owners have done it. What’s your question?
Would it be more hp if I put some piston caps instead of the standard flat tops??? And I appreciate the reply even though it's late...

Watch the video I want my ls similar to that hp.. its beastly!
