"Iam running a 406 sbc with 13.1 Isky roller cam dart 230 and for a while i was running my spark (NGK -9) plug gap at 35, recently i was told to run my gap to 25 because i switch my plate from a NX plate to the Halo plate. Went to the to the track left the line hard but rite when i got to second gear the motor didnt want to rpm any more then i thru third then it started to pick up again the problem lasted for 2 month couldnt figure it out then i went back to my plugs and re gaped them and the motor woke rite up and went down the track just fine i was just wondering where othere people where gaping there plugs at also iam running a Msd Dig 6 box. You should be getting the plate by the mid of the week Steve and Thanks."
