I put a new 351 windsor high output engine in my truck with a edelbrock performer intake on it and the ignition timing is set at 10 degrees btc but the engine spark knocks , so my question is what should i set the timing at to take care of this problem?

What year truck? and what year H.O. 351 did you put in it. When you timed it , did ya dis-connect the SPOUT connector? Maybe you are too far btc, like 14 plus btc and is pinging/knocking? just a guess since we do not know the detail information.

Did you replace with a different displacement motor size, or did the original motor in your 1987 truck also have a 5.8L (351) as well? Reason I am asking is because the firing orders are different between 5.0L and 5.8L engines, and others.
