  |  L29 big block specs  Would anybody be able to get ahold of information regarding an L29 gm engine? its a gen VI 7.4 (454) i wanted to know if they are 4 bolt mains, cam duration and lift, cause i`m considering a cam and going roller fulcrum rockers, and a set of shorty headers. plus a few other flow items. have searched the internet for months, cannot find factory specs, even got a gen v and gen vi rebuild book and its not in there, and not in gm performance catalog. thanks  |
