You have to be INSANE to have long-tube headers on a big-block A-body Mopar!

that is an interesting idea i never considered. however, i don't have a lift to put the car on and i would have to drop the K member with jacks. do you think that could be done? also, this is a 4 speed car. other than dropping the rear transmission cross-member, can the K-member drop while still having the drive train attached? i do want to put a Borgeson mini power steering box in this car and dropping the K frame would also make that much easier. your thoughts?

You don't need a lift. Do you have an engine hoist? You can lift the car right off the K frame. Works good.
