Sbc vortec heads .480 lift single exhaust
I have a very mild build and my issue is I think my exhaust is an extreme bottleneck. The shop did 2.5 to a Y pipe with 2.5 single out. Is this worth fixing and going to true duals or maybe 3 inch out of the Y or will I be just wasting money? Thanks
Could it be a 10114182? If so, it is a Gen V 454, 4 bolt 1991 (or later). Hope that helps..
