What do people think of the YSI

How would a YSI work on a 355 with a 7000rpm red line HR cam

Could this kind of set up push the 800rwhp mark ?

I've seen around 900 RWHP through a powerglide before, 383 SBC with some AFR heads.

you may want to contact RMCR performance out of colorado they may have brackets for the lt1 for that blower.

800 rwhp should be attainable on race gas.
