I've rebuilt a few 305s in near stock configuration and they're not bad for a dependable daily driver if that's what ya have and can get by with rings, bearings, and valve job (and have no "need for speed").. Did one in an early 70's Camaro 4 speed. Stripped off the emission control, had a used HEI w/Accel ignition from a previous project, swap meet Weiand with a Q-jet and headers and 40 series Flowmasters. All for well under $1,000. It was a nice starter car for a 17 year old young lady - 20-22 mpg and fun to drive. She put a bit more into some nice paint and had a great ride.

Just saying the 305 has it's place..
