Ok, I gotta rethink this whole it's a survivor thing, there seems to be lots of these cars with 40k miles on them for reasonable prices so maybe turning it from a survivor to a fun car isn't a sin. I probably should move this to the engine form but are shorty headers worth it or are manifolds almost just as good. I would like to get 325 -350 hp out of the 350 but I really don't want to screw around with leaky headers all the time. Long tubes under that car looks to be out of the question due to the routing of the exhaust and the floor pans.
