496 procharged dyno

Ill give him a shout tonight and finnout about his pulleys, and as for headers they are an old set of custom chassis headers 2" primaries, but they are so old and are starting to get holes blown in them so thats his winter project, i think he said he wants to go 2 1/8 or 2 1/4, back to the pulleys, i know he changed the size of it to spin the blower harder, its at 18lb on a standard f1
