My Chuck Nuytten 850 actually flows around 920! Awesome carb. IF it actually came from Chuck (and some gearhead hasn't played with it since then) you should be good to go on that piece. Timing still might be an issue, but it's not gonna make the car way lean like that.

One mistake we've made in the past was swapping intakes. Went from a single plane (flat carb mount) back to a dual plane (slanted carb mount). What that did to us was made the rear float level WAY too low. Maybe check on that too.

Get an answer from MSD yet? I think they even have the diagrams on there too, hold on I go looky for ya.
