Some good info here, guys. Good stuff. I always took the 307 out in favor of other engines but there is nothing wrong with the 307 unless you want a real tire burner. There are even things you can do to the 307 for more performance that make it a quicker engine though. I wouldn't recommend a big build up on one but they are a solid engine and a good runner. I recommend that you get ALL the shop manuals, did. If you are going to keep the car stock they are a valuable source of info. By the way...I'm not an advocate of a bunch of after market stuff. Like K&N air filters etc. If you have a tuned engine with the parts GM designed you will do fine without spending your money on unnecessary parts. Good luck and keep us posted. I really, really love the 88 Electra wagon.
