Extrude Honing
Reply #2 –
If you want to keep a sleeper stock look under the hood it might be worth it. The 86 Bird that I just bought from Johns331 has an extruded HO intake. On an HO intake you can expect performance to be inline with a stock Cobra/GT40 intake. Otherwise there are much better and/or cheaper alternatives out there such as the Cobra, Edelbrock Performer or the TrickFlow street.
I am concidering selling the extruded HO because I bought a ported Cobra intake just before I bought the 86. PM me if your interested and we could talk about price.
