Looking for suggestions on the cure to my problem. I have two identical engines 460cc Big Blocks that both have intermittent misses at full speed under a load. Runs great on stand but engines Miss while on track during races but not every lap. I have changed coils I have also changed spark plugs and tried different brands of spark plugs. Both also have new fuel pumps.
Any and all suggestions will be greatly appreciated thanks in advance.
