YES a Whole lot better.
5.0L is a 305. 5.7L is a 350
How can you tell a 350 from a 305 engine?
Both are strong engines, but the overwhelming consensus is that the 350 is a better engine, and I agree.
305
Your question is a little vague, so im assuming you're asking which is better between 350 and 305 heads. Many people will tell you it doesnt matter. I think if you have a 350 engine then you should use 350 heads. the 305 heads will have higher compression, which will make the car louder, and somewhat faster, however, if you use 305 heads on a 350 engine then you should use a high octane fuel, so it will be better on your engine. Only use 305 heads if you know what your doing. if not you should probably stick with 350 heads. i hope that answered your question.
it would be a 260 a 350 and 305 are Chevy motors
