so i recently bought a 1983 Cordoba, and now i am gathering info to do a 440 swap. i think i came across a thread somewhere that said you can user a k car brake booster to gain valve cover and header clearance. is this true?, is it a bolt in mod or are mods required? i'm also looking for info on a rear iso delete with a 65-67 b-body 8 3/4. looking at b-body shock plates. can't wait to get started in the spring, thanks.
