So the car has been running great....Supercharged 360 lt1. Ported heads just shy of .600 lift cam with a vortech t-trim. Intank walbro 255 and green top injectors. The other day the car started missing. Its fine when its cold, revs up nice and fast and then when it gets warms it runs like ****!!! you can feel it missing. All plug wires are good, the only thing thats bothering me is when i start to get into the throttle, it starts to backfire and pop. Any suggestions? I need to get this settled to i can sell it

 

two words.. opti spark

 

^Agreed!

 

is there any ways to check this without tearing the motor apart, i was kinda figuring it was that damn thing
