360 TrueStreet Magnum Build
Read Mopar Action. They are currently doing a Magnum low buck buildup that might help with ideas. it's been progressing for the last few issues (and the current one) and they sell back issues.
Seems like the Enginequest iron head is the best thing going for Magnum builders who don't want to go aluminum or really hi buck.
Hope this helps I'll be watching since this idea has merit for me too! Good luck!
