hey guys i im putting in a rebuild 6.0 forged engine into a 2000 trans am and i went with a lonnie fuel system and putting a F1 pro charger on it.
Im trying to find out what plugs i should use for the fi system??????
i was told to go w/ 60 lb injectors but someone just recommended that i go with 80's if any one has any knowledge please give me the heads up???

 

a 7 heat range plug should be pretty good, thread right below yours has a few people in it running ngk br7ef plugs. go ahead and get 80 lb injectors. if that is a dual pump setup those 60's will be maxed long before your fuel system will be and they shouldn't be any harder to tune in than the 60 lbers.

 

NGK TR7 and 80lb injectors should be right on the money.

 

whats the difference between try and br ref???
