88mm is a lot of compressor for only a 650hp goal. A 78/75 would get there with way easier packaging and spool time. An s475 would be a smaller package as well and still have a large enough backside to make power up top. A stock stroke 360 will feel lazy on the street with a 88 in my opinion.
Well the reason I went with the 88mm is because a offered it up for $75 since he went bigger otherwise I hadn't planned on that big. But it's cheap and hardly used
