installing a custom kit on my k2500. using the duramax turbo system. now on the 6.6l, is it a big block or will the monifolds fit my 350? if not what manifolds would i need? or maybe custon? already have the intercooler and piping and the custom brakets already made. just was wondering about the manifolds. thanks
