Charly, 305's don't lift anyone's skirt, but independent of people with a negative outlook on the world, and judged on their own they were "functional". The TPI system functioned well, and has been used in millions of cars. If you're not going for outright performance, and don't intend to drive the car any more aggressively than the Camaros, Firebirds, and whatever else these engines came in you shouldn't be too disappointed. After all, your car weighs less than either of those mentioned above.

The negative comes in the image department. Nearly everyone who sees a Chev small block is conditioned to think 350, and of course there MUST be something wrong with an engine that's smaller. This is the good old US of A and more is better. Rodding mentality just multiplies that line of reasoning. So, you lose points by having a smaller engine, and some day when you go to sell it the marketplace will "punish" you by not valuing the car as highly for not having the larger engine.

If some time in the future you wanted to boost power, the built in limitations that you've (hopefully) read about in other threads archived here will come to roost. If the engine will require rebuilding now or in the not too distant future, then getting a fresh 350 (or larger if you want) would be a better way to go.
