Yep me too! Sure a 350 with the same parts is going to make more power,but my point is the reliability and cost.Most people will sell a good running 305 for nothing or already have a 305.If you need the whole deal and a rebuild with machine work etc.you might as well get a 350 it will cost no more to build than the 305 at that point.But for a motor that basically gets given away and then adding a cam ,headers ,intake and carb and make close to 300 hp is no joke.Then the fact that when you use that motor up ,all the parts will fit a 350 block.Unless you are trying to make 9 gillion hp or going race only there is no reason not to consider the free or almost free 305 you may already have access to.Like said before ,if you need a complete rebuild ,you might as well do a 350. But there is no design flaw in the 305 that warrants absolutly not using a 305 for some situations.

If a 275 hp 305 was under the hood of one of the late 40s to late 50s autos from the factory it would have a legend status like the 327 Untill after the mid 60s a 300 hp street ride was up there in the muscle department.Sure there were blowers and tunnel rams on alot of the cars,but that was far from the norm.Today 300 hp is looked at like a briggs and straton engine and it should be upgraded fast as possible
