Who needs a topswap! Parts are off of a 34k mile, 2004 Impala SS. includes everyting you need to bolt on ANDDDDDD a tuned pcm to your liking.
everything will be cleaned and ready for install. No gaskets to scrape blah blah blah. just wipe er down with some brake clean and bolt it all up. Sh*t ill even paint the heads whatever color you want!
$450 and ill split the actual shipping with you. If you want to send me your pcm for the tune ill knock some $ off the price.
