Hey guys, I finally got around to setting my timing and set it to factory spec which calls for 0 advance, so I set it at 0 degrees.
I start driving it and it knocks under hard accel and when in overdrive at any speed. I tried going with 91 octane (highest I can get) and nothing has changed.
The motor is a rebuilt 383 stroker, mild hyd roller cam (.450", 200 [email protected]
"), 9.4 CR, cast pistons, stock 350 heads, Performer intake, Edelbrock headers, Flowmaster muffler....nothing special. I am running all the factory crap, and California emissions except for an EGR valve and CAT.
I can retard the timing and the knock disappears, but that can't be good for mileage or power.
What do I do now? Thanks guys.
