370 vs 383 ls1
I'm planning to do a build on my ls1 but don't know if I should do a 370 or a 383 build. I've heard the 370 build is better for boost and Easier on gas mileage is this true?

It just depends on the entire build. I just bought a 370 LQ9 forged shortblock from TMS and i'll be running my PRC 5.3 heads along with a pretty big cam and a 100 shot for now. I'm expecting around 440-460 rwhp n/a

You actually can't build a 370ci LS1. 370ci is obtained from a 4.030" bore and 3.622" stroke. Can't take an LS1 block out that far. You would have to start with a 6.0L block. 383ci, for reference, is 3.905" bore and 4" stroke.
That said, smaller cubic inch and shorter stroke is better for boost, thus the reason for many boosted 370ci build. If you plan to boost your 5.7L LS1, I would recommend a 3.905" bore and stock stroke, which would be a 347ci

i luv the ls1
but simple math tells me the 6.0 block build yields more hp capacity n/a.
i can apply the funds used for a stroker kit for the 383 ls1, for the induction on a 4.030 bore. ive been down this road before. and this my opinion based on personal experience. not bench racing
