Default estimated hp?
I recently got a motor with 65k out of a 04 gto. I was just wondering what the estimated hp would be with a good tune. It will have lid, ls6, pacetter headers, slp loudmouth 2, stock 04 gto heads (w.e those are), and a 230/235 590/595 110 lsa cam. thxs guys

The motor itself is prob a little short of 500hp. To the wheels depending if ur auto or manual it would prob be a little over 400rwhp

well something is not right!! the patriot stage 2.5 heads flow more then the 243 heads, so if you dyno 405 w/patriot stage 2.5!! and now with 243 heads you will dyno a little less!!
