5.9 stroker build

I drove this Dart once.
Rich had mentioned that it wasn't as snappy at low rpms as he would have liked. When I drove it, I didn't rap it up high enough to see how it ran over 4000 rpms. I didn't feel right pushing his car hard. I agree though, it doesn't have much low end grunt. My own 67 Dart looks like a junkyard turd next to Rich's car but out of the hole, I could be faster to 60 feet! Mine is just a basically stock 360 with '308 heads and a mild cam.
It is impressive the power that one can get with a stroked LA or Magnum build. I'm a bit more familiar with the B/RB blocks so some of this stuff is new to us both.
My rebuild is just a basic stock stroke with a .040 overbore. THIS build is a huge leap up from stock....
Since the OP used a Metric Liter description, what does that make a 408? 6.7 liters ??
