my cam was running with 108* lobe seperation...most blowers like and are generally recommeded for 110* seperation....ya end up with enough fuel going out the exhaust valve to make em really smell rich, when it is really raw fuel shoving into the heads with exhaust vales not seated closed...my cam was speced for a single 4 tunnel ram..got the blower and thru it on and found out this info,,,looked around at cam profiles for blowers and found the 110* recomendation....some say 109*-110*...but more then not say 110*....changed cam to 110* with same specs otherwise, and it ran stronger, and smelled as if it was burning leaner...but still had the same carb and jets as prior to the cam change....it's setting waiting for the topolino to get running ...then the wagon will probably end up blown and injected..but still be a street rod more then track...did the track thing for 11 years with my sand flopper jeep....
