Thermoquad 1966 Metering Rods

Well carb in car now has 98 jets. Sometimes pings/detonates when I mash the go pedal. Previous carb had .101 jets so it would not ping. A co worker told me the richer jets helped. Engine is a 360 with 340 X-heads, a 292 mopar cam with kb-107 pistons. Intake is a Victor 340. 3.91's out back. Also 727 trans with a 9.5" FTI 3400-3600 stall converter.
