Hillborn Injection size

I am not versed on injection and looking into converting from a carb. Does anyone know what size stacks would be needed for a 565 BBC. There is one for sale locally and it has 2 3/8" stacks and looks to be in good condition with a pump but I am unsure if this can handle that amount of cubic in.

thanks for any info

Call Hillborn and have all your engine and cam specs in hand!

Have your pump flow tested this is the base for all the rest. Then call Hilborn with motor specs.

For a Big Block, Hilborn offers a 2 7/8", a sleeved 3" size (to 2 7/8"), and a full -on 3" Injector-depending on your application (judging by your Avatar), I'd say a 3" would work well-it's part# 396-C-8L-

Thanks for the info
