engine build for reliability

My Wife drives a bone stock (except for HEI ign) 72 Dart 318 with a two barrel and single exhaust.
It has a roller timing set .030 over with a 68 340 style grind hydraulic cam, new MP lifters, new stock 904 trans rebuild, front power discs, power steering and a nice little Pioneer blue tooth/USB stereo with 6x9's.

Totally reliable little beastie and plenty of go for the average female driver.
