im looking at moving from my 96ers to 120s for this season.

any favorites? tips/tricks with them?

i got the 96s to run ok quickly when i switched to them in 2007, but some 160's i had trouble with 0% duty cycle at idle (364ci, 850rpm idle)

thanks guys.

I posted a review of FIC's new high impedance 120s which seemed to be better down low at small pulsewidths than the low impedance Lucas 120s with a driver box. I am running E85 but I would think on gasoline they would be right there towards the bottom of what they can do at idle/decel. I wouldn't think it would be a problem depending on your base fuel pressure, what the engine wants, etc.

Low Imp Standard brand 120's idle well at 14.1 : 1 with BS3. Great injector control. Only problem one stuck closed...could have been the 116 oct...I'm still using them...3 years now.

428 cubes...$448 for the low imp Standards.

so on an 18% bigger engine they were able to idle.

120's are 25% larger than my 96's

My buddy has Racetronix 120's on his 408. Idles and cruises like stock..Great MPG too as long as he stays off it.

I have 120 trick flow injectors in my 5.3 and they idle great. It's one85 also.

I totally forgot you are running a BS3, use the low impedance 120s and save some money over the high impedance 120s since you have an aftermarket computer capable of driving them. I ran the low impedance 120s with a driver on my factory PCM and it ran OK but was slightly rich on decel but it's to be expected with big injectors. I was on E85 with my stock cube motor but I also had the base pressure turned up so depending on what base pressure you would need I think it would be manageable.

yea, e85 needs a lower a/f.. id probably be on easy street with 120's on e85

It's not cheap but I went with twin 96's for the same issue. Problem solved, it really works great.

anyone else? is the standard/racetronix brand the 'go-to' for low-z 120#ers?

There are other places that carry 120's but we are one of the few places that has the proper equipment to supply them in 1% flow-matched sets:

Our ICS is very popular amongst customers who go with large injectors
