Id say 777 is pretty accurate.

After the other mods add another 25-30rwhp.

A typical M6 98 will dyno anywhere from 290-310.

i have NEVER seen an ls1 dyno 270 nor 280 i think the lowest i have EVER seen was like 285 and that was a 98 with a lot of miles and an automatic...average would be 300rwhp for a 98

98' heads weren't all that hot. 99's were better. 00'-02' were the "best" stock heads. With my mods, minus the lid, the guy who I bought the car off of claimed it dynoed 350 rwhp and 350 rwtq UNTUNED. I never saw any documentation for this however. I plan on getting my car tuned shortly. As soon as I do it is going on the dyno to get some numbers. I plan on getting close to 400 rwhp. My buddy works on LS1's all day and he says I should come close to 400. Hope this helps.

The mods might get you around 15 extra. It kind of depends on what you do stock. LS1's may dyno between 290 and 320 rwhp.
