LT1 power ratings were way understated, as the LS1s were too. 275 is a worthless number that can not be used for any kind of power calulcation. FWHP on the lt1 is really more in the 300-305 range.
LT1 A4 fbods typically dyno stock in the 240-250 rwhp range, while many M6s are 250-260 or even 260+.
Plenty of info is available on this site if you folks would care to search.

well i see 275 all over for the LT1 so i went by that. both the LT1 and LS1 were underrated, but seeing as i had no hard evidence on that i went with advertised so if there were dyno sheets that were low than you can compare. ive seen a few A4 dyno sheets on here that were 230-240whp.

If you look at the power stock lt1s put down on the dyno it's quite obvious that the actual fwhp is not 275.
