Hi, I'm new here. I'm about to buy a 71-74 Comet, that supposedly "runs" and has the I6 in it. So at this point, i can get a pontiac "Ford model" 400 4-barrell big block with the carb that needs a rebuild. For the people who don't know, the pontiac 400BB is ford design. Pontiac was close with ford back in 68-78 So what would it take for me to transfer this 69 400BB over to a 71-74 comet? I really want to let my neighbors to have nightmares about the demonic sound theyll hear hehehe.
