I went with a Holley 470 T/A and a Weiand Action + manifold. Happy(ish). Still going to EFI. Lots of folks have good success with the Motorcraft 2100, on a stock 302 I don't know if a 4bbl is all that much of a gain. I didn't want to rebuild my 2100, but knowing what I do now, and having the 470 apart to re-jet, I would have tried fixing the 2100 1st.
