Honestly I was not aware it was a truck manifold, how did you spot that lol? I am most likely going to rebuild that motor or swap it out with a new one, I want somewhere around 350-400hp and fuel injection, eventually.
I spotted truck manifold because my dad has a 1976 ramcharger and his exhaust is just like on your car. Only seen this style on trucks. Supposed to be a good flowing manifold.
