They need a pretty decent cam and a lot of lift to be in the 500hp range on the stock heads with no port work.
A handful of my friends have the new GTOs and Camaros. And I've swapped cars for a day with a couple of them. The new LS cars are fun for awhile, whereas our old pontiac powered cars are fun for a lifetime. Their cars may have been faster than my my 400 pontiac but when they got done driving my car they were in awe of the shear torque over their ls2 and ls3 cars. One of my friends actually just sold his ls2 GTO and is on the hunt for a 68-70 GTO lol.
