Default Help!! What injectors should i be using?

Finishing up with my LSX swap on my 94 BBody block is LQ4 bored out to 400+ Cub. inches. Have All forged Manley internals along with port and polished 243 heads, beehive springs, LSXR 102mm intake and custom grind bullet racing cam. Looking for best option for injectors. Don't want to install top of the line injectors if i dont have to but I also dont want to be pushing the injectors i do have to the max. Looking for recommendations of best injector that will get the job done with ease but not over kill and wasting money where i could save and spend on different part of my swap. Thanks in advance for help!!!

You will probably be good with 42# injectors. I used FAST injectors and haven't had an issue with them

Yep 42's will do you just fine. With my setup I'm only at around 65% cycle duty, so there's plenty of room left

These will fit on the FAST intake with ls2/3 rails or their billet rails with no spacers orings etc. If you need an electric plug adapter for your harness we have them also.

To use an ls1 style 42lb inj youd need a spacer for the rail the spacer kit is ~$25 or so. but they do have the ls1 style connector

http://www.ws6project.com/user_stor/catalog/fast-high-impedance-36-lb-hr-injectors/

Those are FAST 42s even though they show 36lb they are 42lb at 58psi.
