Fuel
My owner manual says 91 Octane. I am running the 350 4bbl with a rochester quadrajet.
I put 87 octane in last fill up and have about 1/2 tank left and I notice the motor wants to hestitate and trys to backfire. Truck sat for the last 4 years in a garage. I am going to change the fuel filter and hope that helps. Do you guys run 91 Octane in your trucks? |
