Two Questions Regarding Boost and Block
 

I have heard a couple of people reference the newer blocks. I was wondering if there was more info somewhere on here (my search attempts didn't find anything)?

Would it be a drop in if I wanted to swap blocks from 2015 to the newer "better" block? Or is there a lot of work to be done?

Does the newer engine hold more boost? I am currently at 8, and wanting to play with a bit higher boost, but it's "not safe." So I was wondering if the new engine is better in that aspect.

Any answers would be greatly appreciated!

The 2017 blocks have minor improvements, not really enough to make it worthwhile to swap it completely. For that amount of money, you could just build your block.

Thanks! Just what I was wondering. Back to plotting a built engine...
