Oh i know a 350 would be better. The only reason i'm going with a 305 is because it came with the car when i bought it. It was my girlfriends fathers car and he thought the v6 was shot, so he bought the 305 for it. So when i bought it i checked the flywheel and saw that it was loose and cracked, as well as the starter being chewed up.
So i want to get a flywheel and starter as easily as possible to see if that was the main problem. However if i can get 350 for a good price around here i'd love to have one.
