Chips for Lucas 38-40 injectors

[ES1]

I have 2 chips for these injectors but sometimes see good deals on other injectors close to these sizes.
So, would chips for 38s work even though these are supposed to be 40s?

TIA

Depends on who's chip you use. Mine would be a bit rich for 40s coming from a 38# injector but some of the other people's chips may do okay. Just depends on how you set the stuff up to run.
