Hi everyone I’m thinking I’m needing 60lbs injectors for Ive built a 540 with an m3 procharger 7lbs of boost. I’m running the mfie3, and mpi intake set up. Can someone please advice me on which injectors? Also I would be very interested on buying a good set of used injectors if anyone has any. Thanks everyone in advance for all help.

What HP do you think you are going to make ?

Check with the guy that just got banned.

I'm thinking you might need 80lb injectors. Smitty (arcticfriends on here) helped size my injectors for N/A 454's that might get boost eventually and we came up with 80lb injectors (with boost). He also steered me to great deals on quality matched sets.

Yup. Look up Arcticfriends posts and threads. He is probably the most experienced na 502 mpi modifier thru blow thru 540 modded engines still using the MPI intake and such. 1050hp or more was the last one ?

what heads do you have?
