428 cj Exhaust Manifolds |
By peter - 10/25/2001 8:28:29 AM; IP 144.134.21.78 |
I was wondering what the Factory exhaust manifold are like as far as performance goes? I'm about to rebuild my 428 cj engine in my mach 1and was thinking about porting the original manifolds. Is this wise or are they to thin or fragile? I'm after a little more power whilst retaining the factory look....... Coming from australia this is my first experience with a big block. Any help would be great. Thanks Peter.... |
