I am currently building a 555 BBC out of a GenVI block and stroker kit I had from another motor. I am really wanting to keep it a EFI setup. I was wondering if I could use a 525efi setup I have found a couple whole setup ready to go. Curious if anyone else has built anything similar with a efi setup and what did they use. Thanks for the help in advance.

It will work, just make sure you get all the parts, 525 is crank fire and 1 coil pack per cylinder, are you going to run closed cooling also
