Anyone out ther having issues with the oxygenated fuels in there big block? Out here in AZ, the fuel gets a 15% hit with Ethanol or some other type of additive in the winter.
Truck starts great but seems lethargic at times.
I am running the Carter 625 cfm with .068"/.042" rods .100" jets and .098" secondary jets. Pump squirter changed from .028" to .043" Rejetted from factory settings of .071/.047 rod .100" jet primary and .095" secondary. The engine is a +.030" 440 with dual plane aluminum Edelbrock, MP 272/.455" cam.TRW flattops near 10:1 compression. 4x4 Truck with 31" tires and 3.21 gears. This stuff (fuel) is bearly fit for my lawnmower. Dear tetraethyl Pb where hast thou gone?
