just done a check. rwhp to fwhp= + 25% fwhp to rwhp= - 20%
so 345fwhp should be 276rwhp approx.

My SS had the 345 package too. With 1500miles on the engine it made 315rwhp @ 326rwtq on a scorching August afternoon. If I could do it over again I would have liked to have seen what it put down after the motor was broken in. If everything is allright you should be in the 315-330 range.
Factory power ratings.

One LS1 engine will never run exactly the same as another LS1 engine. There is always going to be a slight difference. Comparing to another with similar or identical mods may be good guestimate. The only way you're gonna truly know is to get it dynoed.

just looking at the title of this thread it reminds of the joke about the civic. "So...you're saying that my Mountain Dew has more displacement than your civic? so...my Mountain Dew has more horsepower than your Civic?"

Stock I had dynoed 305 rwhp/322 WITH an M-6 With tuning I now have 315rwhp/335rwtq ... down low I gained 25 hp and 30 tq across the board. My car at most trapped 104.7 @13.6 w 2.11 60' (tuned) so my low stock dyno seems to match my #'s I got at NED (13.8's-14.2 @101 - 100% stock) Hope this helps
