Redoing a 289 that currently is bored .030 over with a large cam (.530+ range as I recall), GT40 iron heads, roller rockers and a '66 GT350 high rise manifold and Holley 4bbl. We're leaving the cam but swapping over to aluminum 165cc AFR heads. The big question is should we go with a new reproduction Weber 4-carb 48IDA setup or Paxton SN60 supercharger. What would make better power with a big cam and those heads, and how hard is it to set up and tune Webers? Any thoughts would be great. We're trying to make big power while still maintaining small cubic inches and keeping everything vintage. Thanks,
