500 at the wheels? or at the flywheel? Bolt-ons are always great. Full exhaust. Ls6 intake manifold, knn filter, bellow. What is your budget like?

If you want 500+ at the wheels all motor.. get ready for $10,000 ish for a forged big cube motor.... Maybe more..

Then you always have to upgrade the rear... and the transmission.. Your at the right place to find answers.. However your question can be answered in way to many ways..

Read around on the site.. use the search engine.. Live and learn.

are you going for 500 @ the flywheel or wheels? spraying or not?

if on spray, step up to a 150shot AND h/c/i and some headers to true duals and youll be well over 500 at the wheels

if you arent spraying, might as well got with a roatating assembly for some bigger cubes, or just go and get an assembled engine from our great sponsors. either way you are going to need a good size cam and good heads

i say do some research at texas-speed with the ms4 and 5.3l stage II heads. alot of guys on here put down some good numbers with that setup. with spray and supporting mods u should be over 500rwhp. i don't know how long it will last.

I suggest take some quality time reading up and searching the forum. It looks like your speechless with the new found power of the LS1.
