I know this is an old thread and I just happen to come across it but I put a 360 Magnum in a pink $67 Dodge a100 basically copy to everything that the 380 crate engine has and put it in a 60,000 MI Magnum out of the van it was exact copy except for the compression it put down 272 at the wheels can't remember the torque I want to say 390-410ish 3500 stall and reverse manual valve body. it ran 1270s in Spokane built that thing when I was a freshman in high school so 2002 this winter we finally put in a new long block this winter same as it was before used and that thing was abused and abused and abused more I remember taking a trip in it I was turning 3500 to 4,000 RPMs pretty much the whole trip it was built to be loud and obnoxious and to do burnouts and that's what it did it was abused anytime it moved as long as the battery was good run out there hit the key and fire right up every spring it's sit outside every winter just regular oil changes and maintenance
What did you get for a vacuum reading?
