Have a 468 BBC with 6-71 with Teflon strips non helix. Has birdcatcher with 110 pump and 54 square nozzles in the hat only injection. I started out with 75% leak and 32° timing and it was so rich it was blowing 6 ft flames out of every pipe while idling. Shut it down re leaked it down to 55% and got lil bit better but still rich as hell. I'm stumped? This is in a 33 willys show car that will never be raced even though its certed to 7.50 but my question is what should I leak it to or what nozzles to install in the thing. Yeah those huge flames were cool but definitely couldnt run down the road that way lol. I do have an 80a pump if that would work. I'm used to blown hemi but this chevy has me stumped. It originally came out of a drag boat if that helps.
