Hey guys, I'm doing and LS1 swap in my '75 and I've been told C5 exhaust manifolds work really well for fit. However, I figure since they would fit well, so would shorty headers. Which leads to the question if shorty headers show any real benefit. I would be buying used either way.
So do the shorty headers offer any real performance benefit to the stock cast manifolds? There should be some improvement, but is it significant?
