Default Will LS1 26.8 lb Injectors Work?

I have an extra set of injectors from when I upgraded my LS1. Do you think they'll feed a mild 383 L98? thanks!

Fed mine fine, I also used a dremel to make it so I could use the stock retainer clips. (426/520 at the flywheel )

They should. I have LS6 injectors in my LT1.

BTW, is this the rating on these injectors in the LS1? Be advised that unless you bump your fuel pressure to LS1 specs that they will effectively be a smaller injector in your application.

Good point. I think the LSx engines run at 50psi line pressure. What can I safely adjust the fuel pressure to on a L98? Thanks!

I believe they are rated a 28lb@58psi (LS1 pressure )so probablely more like 24lb at L98 pressure

From Five O site

Bosch LS1 -
Use this set for all 1985-1991 L98, 350cid engines.
This LS1 injector incorporates faster pulse rates and a finer more efficient spray for added power response and economy.

Hmmm. 24lbs should still be adequate, if not optimal., correct? Thanks!
