hey guys im building a 355 stock crank, 6.0 forged scat rods, mahle -5cc forged pistons,heads similiar to le2s, 228/236 .565/.565 110 lsa cam, 1.6 rr, 58mm tb, and walbro 255. compression should be about 11:1. it MAY see a 100 shot plate kit maybe. what do you guys recommend and where to get them thanks

 

i'd think ford redtops would be fine, i have them in my H/C/I ls1 and im not running out of fuel.

 

those are like 30lb injectors right?

 

My motor is setup very close to yours and I'm seeing over 90 percent duty cycle over 6000 RPMs with 32 lb racetronix injectors, if I was doing it again I would get 36 or 42 lb injectors just to be safe and allow for future upgrades.

 

so i wont matter if i get a bigger injector then i need?

 

you may be okay with the ford redtops. You may want to consider 42# just to have some growing room.

 

I am running the green top 42's cause I got them for a steal, if your tuner is worth anything he can make the larger injectors work just fine. Just don't go overboard with larger injectors if you don't need them.

 

I always heard our 24 lb/hr ones were good up to almost 450 rwhp??? Maybe I heard wrong. Perhaps talk to your tuner and see what he recommends for your set-up? I'd think 30's would be enough.

 

Stock injectors will be far maxed out by then - no way.

 

definately not 450hp on stock injectors

 

Maybe they meant 450 flywheel HP then? IDK. Was just repeating what I thought I heard to promote discussion, not trying to state a fact. I know there is a chart showing the recommended sizes based on 43 psi, but don't remember where I saw it. Our cars are tuned to run lower psi than that anyway right?

 

i agree completely, you will be very close with a red top (svo 30#) - i have those and wish i went a little bigger, the next size up racetronix injector looks good (36 or 37 cant remember)

our cars run at 43.5, ford uses 39.5 and that is what there injectors are rated at

 

run a 36 and be done with it. when i was running gas i was about 80% on 42#ers but my setup was alot more radical.

 

isnt there like a ford injector smaller then the red top? but still flows more on a lt1 vs stock lt1 injectors?

 

sorry to hijack but do the make a black top? is it a 60#er

anyone else have any other links? will an ls1 injetor fit an lt1? im looking at a set of 30# svo injectors right now but he dosent know if they will work in an lt1

 

Yes they will. I have them in mine.

 

Im running them in my car also.
