Hey got my 418 LS3 getting shipped to me in a couple days just trying to tie up the loose ends before it goes in. From what iv read 42 lb injectors are the size i need is that correct? Its going in a 98 F body. Let me know what you guys think and if you know any websites that have what i need. Thanks

It depends on how much HP your going to be making.

With the mods in my stroker I'll be needing a 52lb injector.

I would go with 50 or 52 injectors you can have the stock 42 ls3 ones rebuilt to 52, at 42psi with about 520rwhp you will be running about about 100% duty rate

Its got the fast 102 intake and tb, monster stage 2 clutch, 9 in rear, 1 7/8 long tubes 237cc PRC ported heads, LS7S Camshaft: 242/250 .614'/.614' (with 1.7:1 Rocker Ratio), 114 LSA..4:10 gears want to get as close to 550hp as i can....so you think 52 lb injectors should do the trick?

From what I've been told, stock LS3 injectors max out at 550rwhp. Based on your motor and mods, seems to me 52# injectors would be best. Should be a beast.

Give FIC a call, he can hook you up and is very good to deal with as well....

I went with the FAST 58's for my build. It also depends on what intake your going to run as what type of injector will work. Go to the fast site and look it up.
