Perfect, once i get my recipe for my motor ill post it up and see if there are any issues. Ive still got a lot of prep to do before I get to the tear down. But before i order anything im going to get the "go for it" from here, since im rather new at these big blocks. Oh man i hope its in as good of condition as you say, that would make my year! As for headers, again some cheap ones on ebay, LMC sells HEAMANS. Like you said i have heard also other places that these manifold are terrible. So that will probably be one of my few mods... hmm maybe with 3" straight pipes
