Don't think the OP is looking for an exact number just what it more than likely could be on a dyno tuned right. Who knows what it is actually in Net hp (as is in car). If I was the OP I'd say around 350 hp, does it really matter if it's 330 hp or 370 hp or somewhere in between. Now if it's only 250-290 hp and saying 350 hp I'd say saying 350 hp is wrong then.
