still turning wrenchs on these ole broads? may have a leaking valve seal. puff of smoke on startups. one faint puff of white/grey smoke and its gone. will do some more investigation when i get home. I dont know what else it may be. would you be interested in this work if this is what it turns out to be? and what happened to the jannetty 445 cam package. noticed they dont sell it anymore. been away from forums for a while. may have missed something.
a guy i used to work with is looking to do twin turbos on his vette. currently looking for an LS1 to be build to handle it. i sent him your email address. If he is interested then you guys can hash it out.
