I need to put good working engine in my Challenger for a while while I decide what to do with the original small block. All I have is big blocks. The smallest cam is a street hemi grind MP.474 280 which makes anywhere from 9 to 12 inches of vacuum depending on idle, neutral, in gear, engine temp etc. It idles nice in gear at 700 rpm or so. I think I have most of what I need to make the swap without grief. My other engine choices would be more fun, but likely unsafe when it comes to stopping. I kind of thought this might be the lowest vacuum required to retain safe and effective power brakes.


Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen! Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!
