This post is directed to all of you SBC guys. I don't see a lot of info on the 305. I've used a lot of 305's and had terrific luck with them. With just a little tweaking they will perform every bit as good as the 350. Better fuel mileage is just one of the benefits. As though that mattered anyway. There has to be at least a bizzilion of them and that makes them a bit lighter on the wallet. Besides, it does not matter if you have 600 HP, you will never get a Z car to hookup unless you do some very serious chassis work. And that equates to mucho bucks. Something a lot of us home builders have to keep a close eye on. Be assured your wife is. For those of you haven't thought of using a 305, give one a try. You won't be disappointed.
